1.1 This test method covers and focuses on the corrosion resistance of metal, metal-coated, and nonmetallic-coated smooth and deformed shank driven fasteners in contact with treated wood in exterior or high moisture exposure applications using comparative tests with control fastener specimens of standardized benchmarks. This test method may be used for preservative-treated wood.

1.2 This test method describes the apparatus, procedure, and conditions required to maintain test environments for the Cyclic Fog Test and the Steady State Moisture Test.

1.3 This test method describes the types of test samples, lists exposure periods, and gives guidance on interpretation of results.

1.4 Until experience is gained comparing laboratory-to-laboratory results with this test method, comparisons of fasteners, coatings, materials, or preservatives shall be made only within the results of the same test.

1.5 The values stated in SI units are to be regarded as standard. The values in parentheses are for information only.

1.6 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.
