A qualified castor product must be before they go out to the strict quality, performance testing, east east castor was introduce for everybody below red castor co. , LTD. , now USES five types of tests: 1. Resistance performance test when testing the performance castor should keep dry and clean, place the caster in a piece of insulation on the metal plate with the ground, keep the wheel edge in contact with the metal plate, loading casters on its load of 5% to 10%. By measuring insulation resistance tester castor and resistance value between the metal plate. Resistance test 2. Impact test will castor vertical backward installed on the ground test platform, make quality for 5 kg of noon from height is 200 mm, allow 3 mm deviation for the position of the free fall impact caster wheel, if for two rounds of two wheel should be hit at the same time. Impact test 3. Castor static load test of static load test process is the castor in horizontal smooth steel with screws test platform, the center of gravity of the direction along the caster and 24 h 800 n force to maintain, will force excluding 24 h after the check of the condition of the castor, after the experiment measured the deformation of castor does not exceed 3% of the wheel diameter, and the experiment after the completion of the caster roll, circuition or brake function has no damage is qualified. Castor static load test of 4. Reciprocating wear testing castor reciprocating wear test to simulate the casters in daily use the actual rolling, the two points with and without obstacles obstacles test test, the trundle put to the test platform is installed correctly, each test castor load of 300 n, test frequency is ( 6 - 8) Times/min, a test cycle including 1 m and 1 m back to reverse a back and forth movement. In test process are not allowed to have castor or other part out, after the test of each castor should be able to drive its normal function, test after the completion of the caster roll, circuition or brake function should not be damaged. Reciprocating wear test 5. Castor stent usage test/news_120 limit.
