Standard Test Methods for Nails
SIGNIFICANCE AND USE
When specified, the tests selected for application shall be performed to assure conformance with requirements stipulated in the product specification.
SCOPE
1.1 These test methods cover procedures for the testing of nails. The test or tests selected, and the requirements for compliance, will be as specified in the applicable product standard. Performance tests for nail withdrawal and lateral load capability are not included as they are covered by Test Methods D 1761.
1.2 The tests described are as follows:Section Dimensional tests5Tension test6Conventional bend test7Impact bend test8Rockwell hardness test9Coating weight test10Coating adherence test for zinc-coated nails11
1.3 This standard does not purport to address all of the safety problems, 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.
1.4 The values stated in inch-pound units are to be regarded as the standard. The values in parentheses are provided for information purposes only.
