Industrial PP Casters test method

Time:2018-08-15
 
    Before entering the market, Industrial PP Casters will definitely need to conduct corresponding tests in order to meet the standards of use. So what are the common Industrial PP Casters test methods, and what are the requirements in the test?
 
1. Impact test Any item may cause collision vibration due to transportation, use, storage, etc., but the product may be bad or even unusable for a certain period of time. Furniture is often vulnerable to impact due to its large size and weight. Industrial PP Casters, which determine whether the furniture is placed smoothly, should have good impact resistance. The impact test method of the European Industrial PP Casters test standard is: the Industrial PP Casters are vertically mounted on the ground test platform, so that the weight of the mass of 5KG (±2%) is 200mm from the height, and the tolerance is ±3mm. The position of the free fall impacts the wheel of the Industrial PP Casters, if it is two rounds, the two wheels should be impacted at the same time. No part of the caster is allowed to separate throughout the experiment. And after the completion of the experiment, Industrial PP Casters' rolling, pivoting or braking function should not be damaged.

2. Static load test The caster should always run stably on the ground, however it is almost a purely theoretical state. Industrial PP Casters will leave the ground briefly on uneven surfaces or when crossing thresholds, tracks and pits. So when they are suddenly overloaded or if 3 of the 4 Industrial PP Casters are in contact with the ground, they must carry the entire load of the furniture. The European Standard Industrial Cast Caster static load test process is Industrial PP Casters screwed on a horizontally smooth steel test platform, applying a force of 800 N along the center of gravity of the caster to maintain 24H, and checking the Industrial PP after 24 hours of force removal In the Casters condition, the amount of deformation of Industrial PP Casters measured after the experiment did not exceed 3% of the diameter of the wheel, and the rolling of the Industrial PP Casters after the completion of the experiment, the shaft rotation or the braking function was not damaged.
 
3. Resistance performance test When the performance of this test, Industrial PP Casters should be kept dry and clean. Place the Industrial PP Casters on a metal plate insulated from the ground, keep the wheel edge in contact with the metal plate, and load the standard on the Industrial PP Casters. Weigh 5% to 10% of the load. The resistance between the Industrial PP Casters and the metal plate was measured using an insulation resistance tester (nominal open circuit voltage of 500 V, measured resistance fluctuations within 10% and no loss on the product of 3 W). For Conductive Industrial PP Casters, the resistance is not greater than 104 ohms, while the resistance of the antistatic Industrial PP Casters should be between 105 ohms and 107 ohms.
