Preface
This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for standardization work Part 1.Structure and drafting rules for standardization documents"
Drafting is required.
This document replaces GB/T 14020-2006 Hydrogenated Rosin. Compared with GB/T 14020-2006, except for structural adjustment and editorial changes,
In addition to the modifications, the main technical changes are as follows.
Added the term and definition of hydrogenated rosin (see 3.1), and deleted the term and definition of ordinary hydrogenated rosin and highly hydrogenated rosin
(See 3.1 and 3.2 of the.2006 edition);
Added the technical indicators of super highly hydrogenated rosin (see Table 1); -
The Ghana colorimetry was added to the color measurement, and the glass color block colorimetry was deleted (see 6.2.1, Table 1 and 5.1.1 of the.2006 edition); -
Added the gas chromatography determination method for abietic acid and dehydroabietic acid (see 6.8); -
The technical indicators and determination methods of oxygen absorption have been deleted (see Table 1 and 5.7 of the.2006 edition). -
