1.1 本规程涵盖了用沥青材料对波纹钢管和波纹结构钢板进行后涂层。本规程仅适用于车间涂装。 1.2 以英寸-磅单位或国际单位表示的数值应单独视为标准值。每个系统中规定的值不是精确的等价物；因此，在不以任何方式组合值的情况下，独立使用每个系统。为清晰起见，文本中的括号中显示了国际单位，但它们是使用国际单位进行应用时的适用值。 1.3 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、健康和环境实践，并确定监管限制的适用性。 1.4 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）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》中确立的国际公认标准化原则制定的。 ====意义和用途====== 3.1 沥青涂层用于为波纹钢产品（产品）在腐蚀或磨蚀环境中提供额外保护，或同时在腐蚀和磨蚀环境中提供额外保护。

1.1 This practice covers the post coating of corrugated steel pipe and corrugated structural steel plate with asphalt materials. This practice is intended for shop-applied coating only. 1.2 The values stated in either inch-pound units or SI units shall be regarded separately as standard. The values stated in each system are not exact equivalents; therefore, use each system independently of the other, without combining values in any way. The SI units are shown in brackets in the text for clarity, but they are the applicable values when the application is to be performed using SI units. 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.4 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 ====== 3.1 Asphalt coating is used to provide additional protection for corrugated steel products (product) in corrosive or abrasive environments, or both.
