Ki jan yo detèmine si pèfòmans nan rad anti-estatik satisfè estanda a
Anti-rad estatik se yon zouti pwoteksyon souvan itilize nan atelye pwodiksyon mikwoelektwonik, ekspozisyon optoelektwonik, semi-conducteurs, kominikasyon elektwonik ak lòt endistri yo. Lè w ap achte rad anti-estatik, nou pi konsène sou si fonksyon li satisfè estanda a, si li ka efektivman pwoteje pwodwi yo nan liy pwodiksyon an epi asire travay la. sekirite pèsonèl yo.
Ki jan yo detèmine si pèfòmans nan rad anti-estatik nan estanda? Metòd ki pi dirèk la se fè tès rezistans sifas rad anti-estatik. An jeneral, rad anti-estatik ki fèk achte oswa netwaye yo bezwen fè tès pou pèfòmans rad anti-estatik.
Men, anvan ou fè tès rezistans sifas anti-estatik, nou bezwen obsève aparans li an premye, paske twal la ak pwosesis rad anti-estatik afekte pèfòmans rad anti-estatik.

After checking the appearance, let's carry out the surface resistance test of the anti-static clothing. Before the test: prepare the test equipment weight-hammer resistance tester, keep the temperature of the test environment at 18-25 degree , and the relative humidity RH=40-60 percent . Hang the garment to be tested in a standard environment for 24 hours to balance; connect the surface resistance tester with wires, and the tester wears anti-static overalls, wears a wrist strap and is grounded. Start the test: Lay the balanced garment on the insulating board; place the two weights of the surface resistance tester on the same surface of the garment to be tested, and the distance between the two weights is 20cm; press the test button to test , observe the direct reading on the display screen of the instrument, this reading is the surface resistance test value (unit Ω) of the tested sample, and the test result is between 105 and 1011, which is a qualified product.
