Foreword
This Standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This Standard replaces JB/T 10155-1999 "Coated abrasives - Test method of
the grinding properties of abrasive cloth and abrasive paper". Compared with
JB/T 10155-1999, the main technical changes in this Standard are as follows:
- modified the type of abrasive cloth (see Table 1 of this Edition, Table 1 of
Edition 1999);
- added the detailed regulations for grinding time (see Table 1 of this Edition).
This Standard was proposed by China Machinery Industry Federation.
This Standard shall be under the jurisdiction of National Technical Committee
on Abrasives of Standardization Administration of China (SAC/TC 139).
The drafting organizations of this Standard: Zhengzhou Abrasives Grinding
Research Institute.
Main drafters of this Standard: Zhong Yanzheng, Yang Songbin, Zhang
Changwu.
This Standard was issued in 1999 for the first time. This is the first revision.
Coated abrasives - Test method of the grinding
properties of abrasive cloth and abrasive paper
1 Scope
This Standard specifies the test method of the grinding properties of abrasive
cloth and abrasive paper: test equipment, test conditions, specimen preparation,
test procedures and processing of test results.
This Standard is applicable to abrasive cloth, abrasive paper and water-
resistant abrasive paper.
2 Test equipment
2.1 Grinding properties tester
The grinding properties tester shall meet the following requirements:
a) The grinding disc end face of the grinding properties tester does not run
out much 0.05 mm;
b) The grinding disc speed of the grinding properties tester is (320±5) r/min;
c) Grinding track: The ring inner diameter of the track is (87±0.2) mm, and
the ring width is (16.5±0.4) mm.
2.2 Balance
The scale of the balance is 0.01 g.
2.3 Constant temperature water bath
The fluctuation of water temperature is ±2°C.
3 Test conditions
The test conditions for the grinding properties of abrasive cloth and abrasive
paper shall meet the requirements in Table 1.
