Standard Practice for Evaluating the Performance of Mechanical Testing Laboratories (Withdrawn 2002)
SCOPE
1.1 This practice interprets the generic criteria listed in the referenced documents as they apply to mechanical testing. The omission of generic criteria contained in any of the reference documents does not necessarily mean that they are inapplicable to this practice.
1.2 The specific criteria assess features of organization, facilities, personnel, testing procedures, and record keeping to give an indication of the precision of the test results and the validity of the reports produced by a mechanical testing laboratory.
1.2.1 Some specific criteria of this practice may not be applicable when tests are only conducted for the company with which the lab is affiliated or when the tests are conducted on a company's own products and are reported only within the company or to purchasers of those products. When exceptions to this practice exist, the assessor shall be informed of them. The exceptions shall be made available to the assessor if requested.
1.2.2 An appendix applicable to a specific test method further defines the specific criteria listed in the main portion of the practice.
1.2.2.1 The test methods state some requirements without numerical values or recommended procedures for determining whether the requirements are met. One purpose of an appendix is to provide procedures and quantitative values which may be used during assessment. It is not to be considered as the requirements for assessment or for testing according to the method. Only the assessor or the accrediting agency can state requirements for assessment. Similarly, only the responsible subcommittee can state the requirements of the test method. Where mandatory requirements of the test method are referenced, mandatory wording is used in the appendix.
1.2.2.2 For the purposes of this appendix it is assumed that when a measurement is required, some degree of accuracy is implied even if none is stated.
1.2.2.3 If an assessor chooses to require any of these criteria, then the laboratory should be prepared to demonstrate compliance by measurement made during the assessment or to have at hand a report of such measurement made previously.
1.2.3 An appendix covering details peculiar to certain tests is appended to this practice as follows:
1.2.4 The specific test methods and practices applicable to the work of the laboratory and listed in 2.1 should be employed in assessing the capability of the laboratory.
1.3 The laboratory being accredited may be part of a larger organization.
1.4 Testing, approval, and certification of a company's own products or services, or both, by its own laboratory does not constitute a conflict of interest.

This standard is issued under the fixed designation E 1595; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (e) indicates an editorial change since the last revision or reapproval.
INTRODUCTION
Criteria for laboratory assessment are commonly divided into two classes: generic (or general) and
specific. The generic criteria are applicable to all laboratories regardless of the type of test being
performed. Specific criteria are interpretations of the generic criteria applied to more limited areas of
testing, such as a product class, type of test, or a particular test method.
The sources of the criteria for this practice include ISO/IEC Guide 25 (see Section 2), Guide E 548
and Practice A 880. If inconsistencies exist between these documents, the criteria given in this practice
have precedence.
Accreditation is only an indicator of the quality of service furnished by the laboratory and does not
relieve normal contractual responsibilities.
All information gained by an assessor or by an accreditation agency must be treated as confidential.
Such information shall be handled on a “need to know” basis and shall not be divulged without the
express written consent of the laboratory management.
