Foreword
This document complies with the provisions of GB/T 1:1-2020 "Standardization Work Guidelines Part 1: Structure and Drafting Rules of Standardization Documents"
Drafting:
This document replaces GB/T 11834-2011 "Friction Discs for Industrial and Agricultural Machinery": Compared with GB/T 11834-2011, except for structural adjustments
In addition to editorial changes, the main technical changes are as follows:
a) Added a "Terms and Definitions" chapter (see Chapter 3);
b) Changed the requirements for “appearance quality” (see 5:1:2, 4:1:2 of the:2011 version);
c) Changed the index requirements in "Friction Performance" (see 5:3, 4:3 of the:2011 edition);
d) Added the requirement of “relative density deviation” (see 5:4);
e) Changed the requirements for "shear strength" at room temperature and added the requirements for "shear strength" at high temperatures (see 5:7,:2011 edition
4:5);
f) Added the requirement of “limit of hazardous ingredients” (see 5:8);
g) The test method of "friction performance" has been changed (see 6:3, 5:3 of the:2011 edition);
h) Added the test method of "density relative deviation" (see 6:4);
i) Added the determination method of "limit of hazardous ingredients" (see 6:8);
j) The requirements for factory inspection, type inspection, batch grouping principles and sampling in the "Inspection Rules" have been changed (see Chapter 7,:2011 version)
Chapter 6);
k) Changed the requirements for “marking, packaging, transportation and storage” (see Chapter 8, Chapter 7 of the:2011 edition):
