Foreword
This standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces LY/T 1065-1992 "refined light rosin".
This standard has the following changes compared to LY/T 1065-1992 "Refined Light Rosin".
--- Added terms and definitions;
--- Modified the indicators and methods of color;
--- Modified the indicators of softening point and acid value;
---Modified the unit of acid value;
--- Change the measurement method of each indicator to directly refer to the method of GB/T 8146-2003;
--- Added factory inspection and type inspection;
--- Increased the division of batches;
--- Increased transportation regulations;
--- Modified the storage conditions.
This standard is proposed and managed by the Institute of Chemical Industry of Forest Products of the Chinese Academy of Forestry.

Refined light rosin
1 Scope
This standard specifies the terms and definitions, requirements, test methods, inspection rules, and packaging, marking, transportation and storage of refined light rosin.
This standard applies to light-colored rosin which is refined by distillation using turpentine or gum rosin as raw material.
2 Normative references
The following documents are indispensable for the application of this document. For dated references, only dated versions apply to this article.
Pieces. For undated references, the latest edition (including all amendments) applies to this document.
GB/T 8145-2003 Grease rosin

3 Terms and definitions
The following terms and definitions apply to this document.
3.1
A solid natural resin obtained by rosin or gum rosin as a raw material and purified by high temperature and high vacuum distillation. The main chemical component is a monobasic tree.
Fatty acid, representing the molecular formula is C20H30O2.
4 requirements
The refined light-colored rosin is divided into three levels. first, second and third. The technical indicators of refined light rosin at all levels are in accordance with Table 1.
Table 1 Technical indicators of refined light rosin at all levels
Project level two level three
Appearance light yellow transparent solid
Color (iron-cobalt colorimetric)/Ghana color number ≤ 2 3 4
Softening point (ring and ball method)/°C ≥ 78
Acid value/(mg/g) ≥ 175.0 172.0 170.0
Unsaponifiable a/% ≤ 4.0
Ash /% ≤ 0.005 0.008
a Wetland rosin contains a relatively high amount of diterpene neutrals, and the refined light-colored rosin unsaponifiable content is higher.
