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。

本文件代替GB/T14020—2006《氢化松香》，与GB/T14020—2006相比，除结构调整和编辑性

改动外，主要技术变化如下：

—增加了氢化松香的术语和定义（见3.1），删除了普通氢化松香和高度氢化松香的术语和定义

（见2006年版的3.1、3.2）；

—增加了超高度氢化松香的技术指标（见表1）；

—颜色测定增加了加纳比色，删除了玻璃色块比色（见6.2.1，2006年版的表1、5.1.1）；

—增加了枞酸、去氢枞酸的气相色谱测定方法（见6.8）；

—删除了氧吸收量的技术指标和测定方法（见2006年版的表1、5.7）。
