1.1本试验方法涵盖并侧重于通过与标准基准的对照紧固件样本进行比较试验，在外部或高湿度暴露应用中，与处理过的木材接触的金属、金属涂层和非金属涂层光滑和变形的柄驱动紧固件的耐腐蚀性。本试验方法可用于防腐处理的木材。 1.2本试验方法描述了维持循环雾试验和稳态水分试验的试验环境所需的仪器、程序和条件。 1.3本试验方法描述了试验样品的类型，列出了暴露期，并对结果的解释提供了指导。 1. 4在使用本试验方法比较实验室结果获得经验之前，紧固件、涂料、材料或防腐剂的比较只能在相同试验的结果范围内进行。 1.5以国际单位制表示的数值应视为标准值。括号中的值仅供参考。 1.6 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全和健康实践，并确定监管限制的适用性。 ====意义和用途====== 本试验方法提供了用于产生金属腐蚀的受控环境- 与暴露在给定测试环境中的处理过的木材接触的涂层或非金属涂层光滑或变形的柄驱动紧固件。本试验方法提供的信息可用于评估与不同化学木材处理接触的金属、金属涂层或非金属涂层光滑或变形柄驱动紧固件的耐腐蚀性。 结果仅用于比较目的，不得与自然环境中的暴露时间相关。 这些类型测试结果的再现性在很大程度上取决于测试样本的类型和选择的评估标准，以及操作变量的控制。

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. ====== Significance And Use ====== This test method provides controlled environments which are utilized to produce corrosion of metal, metal-coated, or nonmetallic-coated smooth or deformed shank driven fasteners in contact with treated wood exposed to the given test environments. The test method provides information that can be used to evaluate the corrosion resistance of metal, metal-coated, or nonmetallic-coated smooth or deformed shank driven fasteners in contact with different chemical wood treatments. The results shall be used for comparative purposes only and they shall not be correlated to exposure time in natural environments. The reproducibility of results in these types of tests is highly dependent on the type of samples tested and the evaluation criteria selected, as well as the control of the operating variables.
