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。

本文件代替GB/T14020—2006《氫化松香》，與GB/T14020—2006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：

—增加了氫化松香的術(shù)語和定義（見3.1），刪除了普通氫化松香和高度氫化松香的術(shù)語和定義

（見2006年版的3.1、3.2）；

—增加了超高度氫化松香的技術(shù)指標(biāo)（見表1）；

—顏色測定增加了加納比色，刪除了玻璃色塊比色（見6.2.1，2006年版的表1、5.1.1）；

—增加了樅酸、去氫樅酸的氣相色譜測定方法（見6.8）；

—?jiǎng)h除了氧吸收量的技術(shù)指標(biāo)和測定方法（見2006年版的表1、5.7）。
