GB/T 10715-2021Belt drives - V-ribbed belts, joined V-belts and V-belts including wide section belts and hexagonal belts - Electrical conductivity of antistatic belts: Characteristics and methods of test (English PDF)

Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009.

This standard replaces GB/T 10715-2002 "Belt drive V-ribbed belts, combined V belts and single V belts including wide V belts and hexagonal belts.

Conductivity with antistatic tape. requirements and test methods, compared with GB/T 10715-2002, main technical changes except for editorial changes

as follows.

---Modified normative reference documents (see Chapter 2, Chapter 2 of the.2002 edition);

---Added the angle requirements of the test electrode when the wedge surface of the V-ribbed belt is the transmission surface (see 5.2.3.1);

---Added the requirement of the test electrode when the back of the V-ribbed belt is the transmission surface (see 5.2.3.2);

---Added the calculation method and example of the width of the V-ribbed belt (see 5.3);

---Modified the state adjustment and test conditions of the production control test method (see 7.1, 7.1 of the.2002 edition);

---Modified the specified value of the resistance of the belt (see 7.4, 8.6, 7.4, 8.6 in the.2002 edition);

---Added the schematic diagram of the test electrode when the back of the V-ribbed belt is the transmission surface (see 8.6).

This standard uses the redrafting method to amend and adopt ISO 1813.2014 ``Belt Driven V-ribbed Belts, Combined V-belts, and Wide V-belts, Hexagonal Belts

The conductivity of a single V-belt antistatic belt inside. requirements and test methods.

Compared with ISO 1813.2014, this standard has technical differences.

The set vertical single line (︱) is marked, and a list of the corresponding technical differences and their reasons is given in Appendix A.

This standard was proposed by the China Petroleum and Chemical Industry Federation.

This standard is under the jurisdiction of the National Belt Wheels and Belt Standardization Technical Committee (SAC/TC428).

1 Scope

This standard specifies the maximum resistance and

Its test method.

This standard is only applicable to new belts intended to be used in occasions where there is a risk of explosion or fire. The test is set up to ensure that the belt has enough

To discharge the electric charge generated during operation.

In the product control test, it is determined by the national standard or the agreement of relevant parties whether to test each strip of a batch of belts or

A certain percentage of a batch of belts is selected for testing.

Note. For the product acceptance test, the belt manufacturer should determine which electrode and conductive coating material need to be used.
