本标准规定了以下内容:a.零件设计功能所需的表面光洁度标准；b、 表面缺陷和影响表面质量的缺陷的定义；c、 缺陷的允许类型、尺寸和数量的每种几何形状的位置分类。它还通过为生产零件的验收或拒收提供定义的限制和检查指导，确定验收的定量水平。本规范适用于但不限于:T型密封件的表面质量；L-环；带帽T环；带帽L环；凸轮式密封；十字形弹性体；金字塔（Dyna-Bak）封条；方形密封圈；四瓣海豹；U形杯；弹簧激励U形杯；现浇金属垫片密封件

This standard provides the following: a. The required surface finish criteria for the designed function of the parts; b. The definition of surface imperfections and defects that affect surface quality; c. The categories by location for each geometry for the permissible type, size and quantity of defects.It also establishes the quantitative levels of acceptance by providing defined limits and inspection guidance for the acceptance or rejection of production parts.This specification is applicable but not limited to, the surface quality of: T-Seals; L-Rings; Capped T Rings; Capped L Rings; Cammed Type Seals; Cruciform Shaped Elastomers; Pyramid (Dyna-Bak) Seals; Square Ring Seals; Quadruple Lobed Seals; U-Cups; Spring Energized U-Cups; Molded in Place Metal Gasket Seals
