Corrosion test: a. Laboratory: 50 ° C ± 1 ° C, b. Saturated air barrel: 63 ° C ± 1 ° C
Secondly: the finished material is different: the former full-box material can be as long as the traditional PVC reinforced hard plastic plate, and the latter requires an upgraded version of the PP plate material. Because PP boards are more resistant to high temperatures and strong acids than PVC sheets.
Furthermore: the test methods are different:
Neutral salt spray box according to GB/T2423.17-2008, GB/T2423.18-2000 "Basic procedures for electrical and electronic products test Ka", salt spray test methods and GB/T10125-1997, GB/T10587-2006, GB10593. 2-1990, GB/T1765-1979, GB/T1771-2007, GB/T12967.3-2008, GB/T5170.8-2008 and other national standard customization, acid salt spray box in addition to the test methods specified in the national standard, also need Expand IEC, MIL, DIN, ASTM, IS, CNS and other standard settings.
