Determination of anti - sliding coefficient of steel bolting surface
1 Scope
This standard specifies the test principle of measuring the anti-slip coefficient of steel bolting surface, test equipment, test pieces, test procedures, the value of the test results
Revise and test report.
This standard applies to M12 ~ M30 10.9S high strength hexagon head bolt connection and M16 ~ M30 10.9S twisted shear high
Determination of anti - slippage coefficient of steel plate bolted joint with strength bolt connection. Other bolt connection pairs of friction type other metal bolt interface resistance
Determination of slip coefficient can also refer to the use of this standard.

3 Terms and definitions
The following terms and definitions apply to this document.
3.1
Bolted surface boltedconnectplates'surfaces
Bolt the contact surface between the plates to be connected.
3.2
Pre-tension pre-tensionforce
Tighten the bolt, the role of the bolt rod tension or pressure perpendicular to the bolt between the surface.
3.3
Slipforce slipforce
The force at the start of slippage of the bolted surface.
3.4
Anti-slip coefficient anti-slipcoefficient
The ratio of sliding force to pre-tensioning force.
4 test principle
Tensile test machine in the anti-sliding coefficient of the specimen to be stretched to make it slide the sliding force and the bolt sliding surface of the pre-pull side
The sum of force is linear, resulting in anti-slip coefficient.
