前言

本文件按照GB/T1.1—2020《標準化工作導則第1部分：標準化文件的結構和起草規則》的規

定起草。

本文件代替GB/T14020—2006《氫化松香》，與GB/T14020—2006相比，除結構調整和編輯性

改動外，主要技術變化如下：

—增加了氫化松香的術語和定義（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指標（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）；

—刪除了氧吸收量的技術指標和測定方法（見2006年版的表1、5.7）。
