Nature of Operations [Text Block]

(1) NATURE OF OPERATIONS

We are an independent designer, manufacturer and marketer of thermal, mechanical and electrical products that are primarily used by semiconductor manufacturers in conjunction with automatic test equipment ("ATE") in the testing of integrated circuits ("ICs" or "semiconductors"). In addition, in recent years we have begun marketing our thermal products in markets outside the ATE market, such as the automotive, consumer electronics, defense/aerospace, energy, industrial and telecommunications markets.

The consolidated entity is comprised of inTEST Corporation (parent) and our wholly-owned subsidiaries. We have three reportable segments which are also our reporting units: Thermal Products, Mechanical Products and Electrical Products. We manufacture our products in the U.S. Marketing and support activities are conducted worldwide from our facilities in the U.S., Germany and Singapore.

The semiconductor market in which we operate is characterized by rapid technological change, competitive pricing pressures and cyclical market patterns. This market is subject to significant economic downturns at various times. Our financial results are affected by a wide variety of factors, including, but not limited to, general economic conditions worldwide and in the markets in which we operate, economic conditions specific to the semiconductor market and the other markets we serve, our ability to safeguard patented technology and intellectual property in a rapidly evolving market, downward pricing pressures from customers, and our reliance on a relatively few number of customers for a significant portion of our sales. In addition, we are exposed to the risk of obsolescence of our inventory depending on the mix of future business and technological changes within the markets that we serve. As a result of these or other factors, we may experience significant period-to-period fluctuations in future operating results.

Accounting Policies [Abstract]

Significant Accounting Policies [Text Block]

(2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation and Use of Estimates

The accompanying consolidated financial statements include our accounts and those of our wholly-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated upon consolidation. The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Certain of our accounts, including inventories, long-lived assets, goodwill, identifiable intangibles, deferred tax assets and liabilities including related valuation allowances and product warranty reserves, are particularly impacted by estimates.

In the opinion of management, the accompanying unaudited consolidated financial statements include all adjustments (consisting only of normal recurring adjustments) necessary to present fairly the financial position, results of operations, and changes in cash flows for the interim periods presented. Certain footnote information has been condensed or omitted from these consolidated financial statements. Therefore, these consolidated financial statements should be read in conjunction with the consolidated financial statements and accompanying footnotes included in our Annual Report on Form 10-K for the year ended December 31, 2013 filed with the Securities and Exchange Commission on March 27, 2014 (the "2013 Form 10-K").

Reclassification

Certain prior period amounts have been reclassified to be comparable with the current period's presentation.

Inventories

Inventories are valued at cost on a first-in, first-out basis, not in excess of market value. Cash flows from the sale of inventories are recorded in operating cash flows. On a quarterly basis, we review our inventories and record excess and obsolete inventory charges based upon our established objective excess and obsolete inventory criteria. These criteria identify material that has not been used in a work order during the prior twelve months and the quantity of material on hand that is greater than the average annual usage of that material over the prior three years. In certain cases, additional excess and obsolete inventory charges are recorded based upon current market conditions, anticipated product life cycles, new product introductions and expected future use of the inventory. The excess and obsolete inventory charges we record establish a new cost basis for the related inventories. We incurred excess and obsolete inventory charges of $138 and $197 for the six months ended June 30, 2014 and 2013, respectively.

Goodwill, Intangible and Long-Lived Assets

We account for goodwill and intangible assets in accordance with Accounting Standards Codification ("ASC") Topic 350 (Intangibles - Goodwill and Other). Finite-lived intangible assets are amortized over their estimated useful economic life and are carried at cost less accumulated amortization. Goodwill is assessed for impairment at least annually in the fourth quarter, on a reporting unit basis, or more frequently when events and circumstances occur indicating that the recorded goodwill may be impaired. As a part of the goodwill impairment assessment, we have the option to perform a qualitative assessment to determine whether it is more-likely-than-not that the fair value of a reporting unit is less than its carrying amount. If we determine this is the case, we are required to perform a two-step goodwill impairment test to identify potential goodwill impairment and measure the amount of goodwill impairment loss to be recognized. The two-step test is discussed below. If we determine that it is more-likely-than-not that the fair value of the reporting unit is greater than its carrying amounts, the two-step goodwill impairment test is not required.

If we determine it is more-likely-than-not that the fair value of a reporting unit is less than its carrying amount as a result of our qualitative assessment, we will perform a quantitative two-step goodwill impairment test. In the Step I test, the fair value of a reporting unit is computed and compared with its book value. If the book value of a reporting unit exceeds its fair value, a Step II test is performed in which the implied fair value of goodwill is compared with the carrying amount of goodwill. If the carrying amount of goodwill exceeds the implied fair value, an impairment loss is recorded in an amount equal to that excess. The two-step goodwill impairment assessment is based upon a combination of the income approach, which estimates the fair value of our reporting units based upon a discounted cash flow approach, and the market approach which estimates the fair value of our reporting units based upon comparable market multiples. This fair value is then reconciled to our market capitalization at year end with an appropriate control premium. The determination of the fair value of our reporting units requires management to make significant estimates and assumptions including the selection of appropriate peer group companies, control premiums, discount rate, terminal growth rates, forecasts of revenue and expense growth rates, changes in working capital, depreciation, amortization and capital expenditures. Changes in assumptions concerning future financial results or other underlying assumptions would have a significant impact on either the fair value of the reporting unit or the amount of the goodwill impairment charge.

Indefinite-lived intangible assets are assessed for impairment at least annually in the fourth quarter, or more frequently if events or changes in circumstances indicate that the asset might be impaired. As a part of the impairment assessment, we have the option to perform a qualitative assessment to determine whether it is more likely than not that an indefinite-lived intangible asset is impaired. If, as a result of our qualitative assessment, we determine that it is more-likely-than-not that the fair value of the indefinite-lived intangible asset is less than its carrying amount, the quantitative impairment test is required. Otherwise, no further testing is required. The quantitative impairment test consists of a comparison of the fair value of the intangible asset with its carrying amount. If the carrying amount of the intangible asset exceeds its fair value, an impairment loss is recognized in an amount equal to that excess.

Long-lived assets, which consist of finite-lived intangible assets and property and equipment, are assessed for impairment whenever events or changes in business circumstances indicate that the carrying amount of the assets may not be fully recoverable or that the useful lives of these assets are no longer appropriate. Each impairment test is based on a comparison of the estimated undiscounted cash flows to the recorded value of the asset. If impairment is indicated, the asset is written down to its estimated fair value. The cash flow estimates used to determine the impairment, if any, contain management's best estimates using appropriate assumptions and projections at that time.

Stock-Based Compensation

We account for stock-based compensation in accordance with ASC Topic 718 (Compensation - Stock Compensation) which requires that employee share-based equity awards be accounted for under the fair value method and requires the use of an option pricing model for estimating fair value of stock options granted, which is then amortized to expense over the service periods. See further disclosures related to our stock-based compensation plan in Note 7.

Subsequent Events

We have made an assessment of our operations and determined that there were no material subsequent events requiring adjustment to, or disclosure in, our consolidated financial statements for the six months ended June 30, 2014.

Revenue Recognition

We recognize revenue when persuasive evidence of an arrangement exists, delivery has occurred or services have been rendered, the price is fixed or determinable, and collection of the related receivable is reasonably assured. Sales of our products are made through our sales employees, third-party sales representatives and distributors. There are no differences in revenue recognition policies based on the sales channel. We do not provide our customers with rights of return or exchanges. Revenue is generally recognized upon product shipment. Our customers' purchase orders do not typically contain any customer-specific acceptance criteria, other than that the product performs within the agreed upon specifications. We test all products manufactured as part of our quality assurance process to determine that they comply with specifications prior to shipment to a customer. To the extent that any customer purchase order contains customer-specific acceptance criteria, revenue recognition is deferred until customer acceptance.

In addition, in our Thermal and Mechanical Products segments, we lease certain of our equipment to customers under non-cancellable operating leases. These leases generally have an initial term of six months. We recognize revenue for these leases on a straight-line basis over the term of the lease.

With respect to sales tax collected from customers and remitted to governmental authorities, we use a net presentation in our consolidated statement of operations. As a result, there are no amounts included in either our net revenues or cost of revenues related to sales tax.

Product Warranties

We generally provide product warranties and record estimated warranty expense at the time of sale based upon historical claims experience. Warranty expense is included in selling expense in the consolidated financial statements.

Income Taxes

The asset and liability method is used in accounting for income taxes. Under this method, deferred tax assets and liabilities are recognized for operating loss and tax credit carryforwards and for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the periods in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in the results of operations in the period that includes the enactment date. A valuation allowance is recorded to reduce the carrying amounts of deferred tax assets if it is more likely than not that such assets will not be realized.

Net Earnings Per Common Share

Net earnings per common share - basic is computed by dividing net earnings by the weighted average number of common shares outstanding during each period. Net earnings per common share - diluted is computed by dividing net earnings by the weighted average number of common shares and common share equivalents outstanding during each period. Common share equivalents represent stock options and unvested shares of restricted stock and are calculated using the treasury stock method. Common share equivalents are excluded from the calculation if their effect is anti-dilutive.

The table below sets forth, for the periods indicated, a reconciliation of weighted average common shares outstanding - basic to weighted average common shares and common share equivalents outstanding - diluted and the average number of potentially dilutive securities that were excluded from the calculation of diluted earnings per share because their effect was anti-dilutive:

	Three Months Ended June 30,				Six Months Ended June 30,
	2014		2013		2014		2013
Weighted average common shares outstanding - basic		10,436,730		10,371,716		10,415,461		10,349,695
Potentially dilutive securities:
Employee stock options and unvested shares of restricted stock		19,453		22,378		37,106		30,584
Weighted average common shares and common share equivalents outstanding - diluted		10,456,183		10,394,094		10,452,567		10,380,279

Average number of potentially dilutive securities excluded from calculation		94,807		18,462		96,037		28,605

Effect of Recently Issued Amendments to Authoritative Accounting Guidance

In May 2014, the FASB issued new guidance on the recognition of revenue from contracts with customers. This guidance is presented in ASC Topic 606 (Revenue from Contracts with Customers). This new guidance will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. Companies can use either the retrospective or cumulative effect transition method. This new guidance is effective for us on January 1, 2017. Early application is not permitted. We have not yet selected a transition method and we are still evaluating the effect that this guidance will have on our consolidated financial statements and related disclosures.

(3) GOODWILL AND INTANGIBLE ASSETS

Goodwill and intangible assets on our balance sheets are the result of our acquisitions of Sigma Systems Corp. ("Sigma") in October 2008 and Thermonics, Inc. ("Thermonics"), a division of Test Enterprises, Inc. in January 2012.

Goodwill

All of our goodwill is allocated to our Thermal Products segment. There was no change in the amount of the carrying value of goodwill for the six months ended June 30, 2014.

Intangible Assets

The following tables provide further detail about our intangible assets as of June 30, 2014 and December 31, 2013:

We generally amortize our finite-lived intangible assets over their estimated useful lives on a straight-line basis, unless an alternate amortization method can be reliably determined. Any such alternate amortization method would be based on the pattern in which the economic benefits of the intangible asset are expected to be consumed. None of our intangible assets have any residual value.

The following table sets forth changes in the amount of the carrying value of intangible assets for the six months ended June 30, 2014:

Balance - January 1, 2014	$	1,748
Amortization		(185	)
Balance – June 30, 2014	$	1,563

Total amortization expense for the six months ended June 30, 2014 and 2013 was $185 and $232, respectively. The following table sets forth the estimated annual amortization expense for our finite-lived intangible assets for each of the next five years:

2014 (remainder)	$	170

Letters of Credit

We have issued letters of credit as the security deposits for certain of our domestic leases.

(7) STOCK-BASED COMPENSATION

As of June 30, 2014, we had unvested restricted stock awards granted under stock-based employee compensation plans that are described more fully in Note 14 to the consolidated financial statements in our 2013 Form 10-K.

In addition, at our annual meeting on June 25, 2014, our stockholders approved the inTEST Corporation 2014 Stock Plan (the "2014 Stock Plan"). The 2014 Stock Plan permits the granting of stock options, restricted stock, stock appreciation rights or restricted stock units for up to 500,000 shares of our common stock to directors, officers, other key employees and consultants.

As of June 30, 2014, total compensation expense to be recognized in future periods was $386. The weighted average period over which this expense is expected to be recognized is 3.2 years.

Restricted Stock Awards

We record compensation expense for restricted stock awards (nonvested shares) based on the quoted market price of our stock at the grant date and amortize the expense over the vesting period. Restricted stock awards generally vest over four years. The following table shows the allocation of the compensation expense we recorded during the three and six months ended June 30, 2014 and 2013, respectively, related to nonvested shares:

	Three Months Ended June 30,				Six Months Ended June 30,
	2014		2013		2014		2013
Cost of revenues	$	3	$	2	$	6	$	3

General and administrative expense		24		19		53		37
	$	33	$	31	$	74	$	58

There was no compensation expense capitalized in the six months ended June 30, 2014 or 2013.

The following table summarizes the activity related to nonvested shares for the six months ended June 30, 2014:

	Number of Shares			Weighted Average Grant Date Fair Value

Accounting Policies, by Policy (Policies)

6 Months Ended

Jun. 30, 2014

Accounting Policies [Abstract]

Basis of Presentation and Use of Estimates [Policy Text Block]

Reclassification, Policy [Policy Text Block]

Reclassification

Certain prior period amounts have been reclassified to be comparable with the current period's presentation.

Inventory, Policy [Policy Text Block]

Inventories

Inventories are valued at cost on a first-in, first-out basis, not in excess of market value. Cash flows from the sale of inventories are recorded in operating cash flows. On a quarterly basis, we review our inventories and record excess and obsolete inventory charges based upon our established objective excess and obsolete inventory criteria. These criteria identify material that has not been used in a work order during the prior twelve months and the quantity of material on hand that is greater than the average annual usage of that material over the prior three years. In certain cases, additional excess and obsolete inventory charges are recorded based upon current market conditions, anticipated product life cycles, new product introductions and expected future use of the inventory. The excess and obsolete inventory charges we record establish a new cost basis for the related inventories. We incurred excess and obsolete inventory charges of $138 and $197 for the six months ended June 30, 2014 and 2013, respectively.

Goodwill Intangible and Long Lived Assets [Policy Text Block]

Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block]

Stock-Based Compensation

We account for stock-based compensation in accordance with ASC Topic 718 (Compensation - Stock Compensation) which requires that employee share-based equity awards be accounted for under the fair value method and requires the use of an option pricing model for estimating fair value of stock options granted, which is then amortized to expense over the service periods. See further disclosures related to our stock-based compensation plan in Note 7.

Subsequent Events, Policy [Policy Text Block]

Subsequent Events

We have made an assessment of our operations and determined that there were no material subsequent events requiring adjustment to, or disclosure in, our consolidated financial statements for the six months ended June 30, 2014.

Revenue Recognition, Policy [Policy Text Block]

Revenue Recognition

We recognize revenue when persuasive evidence of an arrangement exists, delivery has occurred or services have been rendered, the price is fixed or determinable, and collection of the related receivable is reasonably assured. Sales of our products are made through our sales employees, third-party sales representatives and distributors. There are no differences in revenue recognition policies based on the sales channel. We do not provide our customers with rights of return or exchanges. Revenue is generally recognized upon product shipment. Our customers' purchase orders do not typically contain any customer-specific acceptance criteria, other than that the product performs within the agreed upon specifications. We test all products manufactured as part of our quality assurance process to determine that they comply with specifications prior to shipment to a customer. To the extent that any customer purchase order contains customer-specific acceptance criteria, revenue recognition is deferred until customer acceptance.

Standard Product Warranty, Policy [Policy Text Block]

Product Warranties

We generally provide product warranties and record estimated warranty expense at the time of sale based upon historical claims experience. Warranty expense is included in selling expense in the consolidated financial statements.

Income Tax, Policy [Policy Text Block]

Income Taxes

The asset and liability method is used in accounting for income taxes. Under this method, deferred tax assets and liabilities are recognized for operating loss and tax credit carryforwards and for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the periods in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in the results of operations in the period that includes the enactment date. A valuation allowance is recorded to reduce the carrying amounts of deferred tax assets if it is more likely than not that such assets will not be realized.

Earnings Per Share, Policy [Policy Text Block]

Net Earnings Per Common Share

Net earnings per common share - basic is computed by dividing net earnings by the weighted average number of common shares outstanding during each period. Net earnings per common share - diluted is computed by dividing net earnings by the weighted average number of common shares and common share equivalents outstanding during each period. Common share equivalents represent stock options and unvested shares of restricted stock and are calculated using the treasury stock method. Common share equivalents are excluded from the calculation if their effect is anti-dilutive.

The table below sets forth, for the periods indicated, a reconciliation of weighted average common shares outstanding - basic to weighted average common shares and common share equivalents outstanding - diluted and the average number of potentially dilutive securities that were excluded from the calculation of diluted earnings per share because their effect was anti-dilutive:

	Three Months Ended June 30,				Six Months Ended June 30,

Weighted average common shares outstanding - basic		10,436,730		10,371,716		10,415,461		10,349,695
