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)。
