Introduction of JB/T 7902-1999

JB/T 7902-1999 本标准非等效采用国际标准 ISO 1027：1983《无损检验用射线影像质量指示计的规则与标志》，对 JB/T 7902-95《线型象质计》的修订。修订时仅按有关规定作了编辑性修改，技术内容没有变化。本标准规定了线型像质计（以下简称像质计）的制造技术，标志及有关应用方法。该像质计用于衡量金属材料 x 或 γ 射线照相的影像质量。当本标准规定的像质计不能满足使用要求时，可另行设计相应的特殊象质计。本标准于 1985 年 11 月 25 日以 GB 5618-85 首次发布，于 1996 年 4 月调整为 JB/T 7902-95。
