本规范涵盖四个等级和四个等级的不燃耐火涂料，适用于挥发性有机化合物（VOC）含量空气污染法规适用于油漆溶剂和特定选定表面的情况。除痕量外，所有等级均不含铅、铬、镉和石棉（见3.5.4）。所有等级的有害空气污染物（HAP）水平均不超过适用的国家有害空气污染物排放标准（NESHAP）水平（见3.5.3和3.9）。根据美国环境保护局（EPA）在本规范日期生效的法规，干涂层残留物和碎屑属于非危险废物。

This specification covers four classes and four grades of nonflaming, fire-resistant coatings which are suitable for use where volatile organic compound (VOC) content air pollution regulations apply for solvents in paints and for application over certain selected surfaces. Except for trace levels, all grades are free of lead, chromium, cadmium, and asbestos (see 3.5.4). All grades have levels of hazardous air pollutants (HAPs) that do not exceed applicable National Emission Standards for Hazardous Air Pollutants (NESHAP) levels (see 3.5.3 and 3.9). Dry coating residues and debris are non-hazardous waste under U.S. Environmental Protection Agency (EPA) regulations in effect on the date of this specification.
