1.1 本试验方法涵盖并侧重于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柄驱动紧固件的耐腐蚀性，使用标准基准的对照紧固件样品进行对比试验。本试验方法可用于防腐处理过的木材。 1.2 本试验方法描述了保持循环雾试验和稳态湿度试验的试验环境所需的仪器、程序和条件。 1.3 该测试方法描述了测试样本的类型，列出了暴露时间，并对结果的解释提供了指导。 1.4 在获得使用该测试方法进行实验室与实验室结果比较的经验之前，紧固件、涂层、材料或防腐剂的比较只能在同一测试的结果范围内进行。 1.5 以国际单位制表示的数值应视为标准。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）。本标准的使用者有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.7 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。 ===意义和用途====== 5.1 该试验方法提供了用于产生金属、金属涂层或非金属腐蚀的受控环境- 涂层光滑或变形的柄驱动紧固件，与暴露于给定测试环境的处理过的木材接触。该测试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。 5.2 结果仅用于比较目的，不得与自然环境中的暴露时间相关。 5.3 这些类型测试结果的再现性在很大程度上取决于测试样品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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 5.1 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. 5.2 The results shall be used for comparative purposes only and they shall not be correlated to exposure time in natural environments. 5.3 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.
