Test setup:
The platform is controlled by the tester and can rotate continuously from the horizontal position between 0° and 45° with an angle accuracy of 0.2°. The effect on the angle due to the tester walking on an inclined plane should not exceed 0.5°. The platform is also equipped with a water spray device that can spray the detergent solution on the specimen surface at a flow rate of (6.0± L0)L/min during the test.
Test Principle:
The tester walks back and forth on the slope with a certain slope paved with the test piece, and gradually increases the angle of the slope during the walking process until the limit angle can walk safely on the slope. This is used as a critical angle to reflect the degree of slip resistance of the surface of the specimen.
