1.1 This test method determines the puncture resistance of a protective clothing material specimen by measuring the force required to cause a pointed puncture probe to penetrate through the specimen. This test method describes three protocols that may be used: Method A, Method B, and Method C.

1.2 The values stated in SI units are to be regarded as the standard. The values in inch-pound units in brackets are for information purposes only. The values stated in each system may not be exact equivalents; therefore, each system must be used independently of the other, without combining values in any way.

1.3 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.

5.1 This test method evaluates puncture resistance of protective clothing materials which may include plastics or elastomeric films, coated fabrics, flexible materials, laminates, or textile materials.

5.2 This test method is not intended to measure puncture resistance of all types of punctures encountered using protective clothing material. This test method involves a procedure where a puncture probe of specified dimensions is used for puncturing specimens.

5.3 This test method evaluates puncture resistance of protective clothing materials, specifically for puncture forced on specimens perpendicular to material surface. There is no supporting structure under the material specimen.

5.4 Evaluation of puncture resistance for snag-type puncture should be performed in accordance with Test Method D2582.
