前言

本文件按照GB/T1.1—2020《标准化工作导则第1部分：标准化文件的结构和起草规则》的规

定起草。

本文件是GB/T27995《半成品镜片毛坯》的第2部分。GB/T27995已经发布了以下部分：

——第1部分：单焦和多焦；

——第2部分：渐变焦。

本文件代替GB27995.2—2011《半成品眼镜片毛坯第2部分：渐变焦镜片毛坯规范》，与

GB27995.2—2011相比，除结构调整和编辑性改动外，主要技术变化如下：

a）增加了规范性引用的GB/T10050（见5.1.1）；

b）删除了30mm的鉴别区域（见2011年版的5.4.1）。

本文件修改采用ISO10322⁃2：2016《眼科光学半成品眼镜片毛坯第2部分：渐进焦和渐退焦

眼镜片毛坯规范》。

本文件与ISO10322⁃2：2016相比，在结构上有部分调整，两个文件之间的结构编号变化对照一览

表见附录A。

本文件与ISO10322⁃2：2016的技术差异及其原因如下：

——用规范性引用的GB/T26397替换了ISO13666，并增加了规范性引用的GB45184（见第

3章），以适应我国的技术条件、增加可操作性；

——用规范性引用的GB/T10050替换了ISO7944（见5.1.1），以适应我国的技术条件、增加可操

作性；

——用规范性引用的GB/T17341替换了ISO8598（见附录C），以适应我国的技术条件、增加可

操作性；

——删除了基本要求（见ISO10322⁃2：2016的5.1），以适应我国的技术条件、增加可操作性；

——增加了几何尺寸试验方法（见6.3），以适应我国的技术条件、增加可操作性；

——更改了标记内容（见第7章，ISO10322⁃2：2016的7.1.1和7.1.2），以适应我国的技术条件；

——更改了标志内容（见第8章，ISO10322⁃2：2016的7.2和7.3），以适应我国的技术条件；

——删除了本部分的参考说明（见ISO10322⁃2：2016的第8章），以适应我国的技术条件；

——将资料性附录“用焦度计测量附加面焦度”更改为规范性附录（见附录C，ISO10322⁃2：2016

的附录B），以适应我国的技术条件。

本文件做了下列编辑性改动：

——为与我国现有标准协调，标准名称修改为《半成品镜片毛坯第2部分：渐变焦》；

——在表1中增加了注2。
