1.1 This guide provides a categorization scheme for uniformly listing the accredited capabilities of a testing laboratory. The categorization scheme consists of three parts. Part One identifies laboratory capability by testing technology or field of testing (chemical testing, mechanical testing, etc.). These are listed numerically in alphabetical order starting with acoustic and vibration. Part Two identifies the laboratory capability in terms of the product or service it normally tests (automotive products, drugs, foods, etc.). Part Three identifies specific test methods performed by the laboratory. Examples are given (for example, Test Method B117 and Salt Spray, SA J 423 etc.).

1.2 In listing the capability in a directory or advertisement, the descriptors for testing technology (see Part One), product or service (see Part Two) along with an example of test methods (see Part Three) the laboratory is competent to perform are normally used.

1.3 The list of testing technology and product categories are not all-inclusive. Laboratories using this guide and wanting to express their testing technology or product capability not identified in this guide are invited to include these new areas under an appropriate category.

1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
