Introduction Because of the convenience, efficiency, and coziness that they bring into our homes, appliances have evolved into an absolutely necessary component. The proliferation of electronic devices in the house, on the other hand, raises the risk of electromagnetic interference (EMI), which may occur between various electronic components. Because to electromagnetic interference (EMI), the perf...
Household and similar electrical appliances –Test Finger Nail Safety 1 Scope IEC 60335-1 This International Standard deals with the safety of electrical appliances for household and similar purposes, their rated voltage being not more than 250 V for single-phase appliances and 480 V for other appliances. Appliances not intended for normal household use but which nevertheless may be a source ...
Ozone aging test chamber is mainly used in rubber industry; According to the test method and standard, it can be divided into “static” and “dynamic”. Static generally refers to putting the test piece into the test chamber for test after being stretched, and dynamic means putting the sample on the fixture of the test chamber, and doing the test while stretching. The outer bo...
