前言

本文件按照GB/T1.1—2020《標(biāo)準(zhǔn)化工作導(dǎo)則第1部分：標(biāo)準(zhǔn)化文件的結(jié)構(gòu)和起草規(guī)則》的規(guī)

定起草。

本文件是GB/T27995《半成品鏡片毛坯》的第2部分。GB/T27995已經(jīng)發(fā)布了以下部分：

——第1部分：?jiǎn)谓购投嘟梗?/p>

——第2部分：漸變焦。

本文件代替GB27995.2—2011《半成品眼鏡片毛坯第2部分：漸變焦鏡片毛坯規(guī)范》，與

GB27995.2—2011相比，除結(jié)構(gòu)調(diào)整和編輯性改動(dòng)外，主要技術(shù)變化如下：

a）增加了規(guī)范性引用的GB/T10050（見(jiàn)5.1.1）；

b）刪除了30mm的鑒別區(qū)域（見(jiàn)2011年版的5.4.1）。

本文件修改采用ISO10322?2：2016《眼科光學(xué)半成品眼鏡片毛坯第2部分：漸進(jìn)焦和漸退焦

眼鏡片毛坯規(guī)范》。

本文件與ISO10322?2：2016相比，在結(jié)構(gòu)上有部分調(diào)整，兩個(gè)文件之間的結(jié)構(gòu)編號(hào)變化對(duì)照一覽

表見(jiàn)附錄A。

本文件與ISO10322?2：2016的技術(shù)差異及其原因如下：

——用規(guī)范性引用的GB/T26397替換了ISO13666，并增加了規(guī)范性引用的GB45184（見(jiàn)第

3章），以適應(yīng)我國(guó)的技術(shù)條件、增加可操作性；

——用規(guī)范性引用的GB/T10050替換了ISO7944（見(jiàn)5.1.1），以適應(yīng)我國(guó)的技術(shù)條件、增加可操

作性；

——用規(guī)范性引用的GB/T17341替換了ISO8598（見(jiàn)附錄C），以適應(yīng)我國(guó)的技術(shù)條件、增加可

操作性；

——?jiǎng)h除了基本要求（見(jiàn)ISO10322?2：2016的5.1），以適應(yīng)我國(guó)的技術(shù)條件、增加可操作性；

——增加了幾何尺寸試驗(yàn)方法（見(jiàn)6.3），以適應(yīng)我國(guó)的技術(shù)條件、增加可操作性；

——更改了標(biāo)記內(nèi)容（見(jiàn)第7章，ISO10322?2：2016的7.1.1和7.1.2），以適應(yīng)我國(guó)的技術(shù)條件；

——更改了標(biāo)志內(nèi)容（見(jiàn)第8章，ISO10322?2：2016的7.2和7.3），以適應(yīng)我國(guó)的技術(shù)條件；

——?jiǎng)h除了本部分的參考說(shuō)明（見(jiàn)ISO10322?2：2016的第8章），以適應(yīng)我國(guó)的技術(shù)條件；

——將資料性附錄“用焦度計(jì)測(cè)量附加面焦度”更改為規(guī)范性附錄（見(jiàn)附錄C，ISO10322?2：2016

的附錄B），以適應(yīng)我國(guó)的技術(shù)條件。

本文件做了下列編輯性改動(dòng)：

——為與我國(guó)現(xiàn)有標(biāo)準(zhǔn)協(xié)調(diào)，標(biāo)準(zhǔn)名稱修改為《半成品鏡片毛坯第2部分：漸變焦》；

——在表1中增加了注2。

請(qǐng)注意本文件的某些內(nèi)容可能涉及專利。本文件的發(fā)布機(jī)構(gòu)不承擔(dān)識(shí)別專利的責(zé)任。

引言

半成品鏡片毛坯是處方定制鏡片的重要元件，不僅能快速實(shí)現(xiàn)顧客個(gè)性化需求，還能有效提升鏡

片加工時(shí)效，優(yōu)化鏡片庫(kù)存，降低因鏡片長(zhǎng)期存放引起的老化風(fēng)險(xiǎn)。

GB/T27995《半成品鏡片毛坯》作為與強(qiáng)制性國(guó)家標(biāo)準(zhǔn)配套的推薦性國(guó)家標(biāo)準(zhǔn)，由2個(gè)部分構(gòu)成。

——第1部分：?jiǎn)谓购投嘟?。目的在于確立單焦和多焦半成品鏡片毛坯表面的光學(xué)和幾何特性的

要求及相關(guān)的試驗(yàn)方法，提升加工水平。

——第2部分：漸變焦。目的在于確立漸變焦半成品鏡片毛坯表面的光學(xué)和幾何特性的要求及相

關(guān)的試驗(yàn)方法，提升加工水平。
