Application: This experiment device is designed according to the "ball pressure test " requirements in GB2099 standards, mainly used for heat testing in household and similar plug sockets products. It is the necessary equipment for relevant manufacturers and qc department for product quality inspection and control. Technical parameters: 1. Ball diameter 5mm(R2.5mm) 2. Total Test pressure 20N±0.2N 3. Sample support stand:diameter 50mm, length100mm,stainless steel solid cylinder 4. Producing Materials: all made of stainless steel 5. Reference standard: GB4706.1-2005,GB2099.1-2008,GB/T5159.21-2006,IEC60695-10-2:2003 Notes: Supporting the use of the Ball pressure test we also Need two extremely hot ovens additional. Usage: The ball pressure test is making the the metal ball (R2.5mm) and the 20N ± 0.2N ball pressure test apparatus to pressure the testing sample surface which was placed in a heating box in standard state. After 60min +2 min/0min under specified temperature of the sample test, fastly (<10s) put the test sample in 20 ° C ± 5 ° C water, cooling 6min. Within 3min after removing from water, measure surface indentation diameter of the test product , to see if it’s indentation diameter is more than 2mm or not to evaluate the test sample Heat-resisting deformation capacity under the specified temperature 1. According to the test requirements,first put the ball test device in heating box for a long and enough time to ensure that the ball pressure device has achieved stable testing temperature before starting testing. 2. Putting the tested parts on the supporting base, make it direct contact to supporting base. 3. Putting the surface of tested parts in a horizontal position,press this surface by steel ball(See below).The Test should operate in the standard temperature heating box.
