Abstract: Introduction: * the new national standard GBT 10006-2021 for measuring the friction coefficient of plastic film and sheet will be formally implemented on October 1, 2021. Although the new standard and the old standard for film friction coefficient instrument are not changed on the whole, the new standard also increases the requirement of 500mm / min in addition to the requirement of 100 mm / min, This makes many enterprises and institutions with existing friction coefficient meters face a great impact, because most of the old friction coefficient meters have large test speed of only 300 mm / min
Gbt10006-2021 new standard for measuring friction coefficient of plastic film sheet

Introduction: * the new national standard GBT 10006-2021 for measuring the friction coefficient of plastic film and sheet will be officially implemented on October 1, 2021. Although the new standard has little change with the old one, the new standard also increases the requirement of 500mm / min in addition to the requirement of 100 mm / min, This makes many enterprises and institutions with existing friction coefficient meters face a great impact, because most of the old friction coefficient meters have large test speed of only 300 mm / min

In order to facilitate the relevant units to better understand and master the situation of the new version of the standard, the special arrangement is as follows:
1、 Main modification contents of new national standard gbt10006-2021 film friction coefficient meter
This standard is in accordance with GB / T1 1-2009.
Compared with GB / t10006-1988, the main technical changes of this standard are as follows:
Revised scope (see Chapter 1, Chapter 1 of 1988 edition);
Revised normative references (see Chapter 2, Chapter 2 of 1988 edition);
Revised terms and definitions (see Chapter 3, Chapter 3 of 1988 edition);
The note "the friction coefficient of thin film is usually between 0.2 and 1" is added (see Note 1 of 3.4.2);
The principle was modified (see Chapter 4, Chapter 4 of 1988 edition);
The requirement of "the slide or platform can be used as the moving part" is added, and the figure 1 is modified and the figure 2 is deleted (see 5.1, figure 1, figure 2 of the 1988 edition);
The nomenclature, clause order and structure of "test device" are revised (see Chapter 5, Chapter 5 of 1988 edition);
The test speed setting requirement of "500mm / min soil 10mm / min" is added (see 5.2.3);
The inspection requirements for conversion time when using the force measuring system of tensile testing machine are added (see 5.2.4);
"Direct connection of slide block and load cell" is changed to "spring is replaced by rigid connection" (see 5.2.5, 1985 version 5.6);
The overshoot requirement of friction coefficient is added (see note 5.2.5);
The requirements for test specimens have been modified (see Chapter 6, Chapter 7 of 1988 edition);
State regulation was modified (see Chapter 7, Chapter 8 of 1988 edition);
General rules for test procedures are added (see 8.1);
The test procedures of "film to film" and "film to metal or other articles" are modified (see 8.2, 8.3, 9.1 and 9.2 of 1988 edition);
The calculation results of static friction coefficient and dynamic friction coefficient are modified (see 9.1 and 9.2, 10.1 and 10.2 of 1988 edition);
The requirement of "significant figures of result calculation" was deleted (see 10.3 of 1988 edition);
The description of precision has been added (see Chapter 10);
Revised the test report requirements (see Chapter 11, Chapter 11 of 1988 edition);
Added "preliminary precision" (see Appendix A).
In this standard, the translation method is equivalent to iso8295:1995 "determination of friction coefficient of plastic film and sheet".

2、 Provisions on test speed in gbt10006-2021

The major change of this standard is that the test speed is 500mm / min, which is 5 times of the original test speed; When the friction coefficient of the tested plastic materials is high, the test speed of 100 mm / min may lead to the low precision of the test results. In order to verify whether the test speed can be replaced by 500 mm / min, a friction coefficient test between different laboratories was carried out in 1993. This test is not only used to evaluate the substitutability of test speed, but also to obtain the test precision preliminarily. The test precision obtained shows that the test speed of 100 mm / min is suitable for all materials in this experiment.
3、 Other modifications of the new edition of GBT 10006-2021
There are 10 pages in the standard, which can not be analyzed one by one. However, compared with the 1988 standard, there are still some big changes in the standard, such as the film to film friction coefficient instrument, the film to metal friction coefficient instrument, and the precision characterization and test methods.

As one of the representative enterprises of the new generation of intelligent friction coefficient instrument, Jinan Chenchi instrument is willing to strengthen the communication with the industry. If we need detailed information, we will conduct in-depth interpretation of the new film friction coefficient instrument in the form of technical exchange.
