Scope and applicable standards for dust test chamber
With the rapid development of modern industrial technology, electrician and electronic products application areas are growing, and the environmental conditions they have experienced also Come complex and diverse. Only the environmental conditions of the product are reasonably specified, and the environmental protection measures to properly choose the product can ensure that the product is avoided in storage and transportation, which is safe and reliable during use. Thus, electrician and electronic products are manually simulated environmental tests to ensure its high quality group *. Artificial simulation environmental test is a scientific summary of the actual environmental impact, with typical, standardized, convenient use, easy comparison. The variety of environmental conditions and the importance of environmental tests also put forward more stringent requirements for environmental test equipment.
Low-voltage electrical appliances, instruments, instruments, various lamps and other products, often by the dust environment during , transportation and action, In particular, the effect of automotive electrical appliances is more significant, and this device is an artificially simulated dust environment to test test equipment for dustproof capabilities. The basic structure and principles and performance of this device, in addition to satisfying national standards related to the dust test method, it is also possible to provide a vertical circulating gas stream of non-layer-free dust-lifting dust, which has a circulating function that can be observed. And the circulating dust-free air flow can smoothly speed up and turn off automatic or continuous control, which is an ideal dust test equipment.
This device can provide corresponding environmental simulation and acceleration tests for research, product development and quality control. Equipment meets national standards GB 2423.37mdash 2006LA2 dust test method, GB 4208-2008 Shell protection rating (IP code), GB / T4942-93 Low-voltage electrical shell protection rating, GB / T 10485mdash 2007, GB 7001MDash 96 dust testand the like.
