Pi wo chaj sifas admisib pou materyèl ki souvan itilize nan estanda tiyo chofaj elektrik, Sous: Repiblik Pèp la Lachin endistri machin estanda JB/T 2379-2016 "Eleman Echafodaj elektrik Echafodaj metal"
5.1.5 Materyèl:
Materyèl yo itilize pou fabrike eleman yo ta dwe rezonab chwazi selon kondisyon itilizasyon yo, yo ta dwe konsidere kondisyon travay yo, epi yo ta dwe satisfè dispozisyon ki nan estanda kalite yo.
Materyèl komen pou tib metal konpozan, karakteristik medya yo akseptab ak tanperati maksimòm opere Gade Tablo 1.
Chaj sifas ki pi wo akseptab nan materyèl souvan itilize pou tib metal eleman nan medya komen yo dwe konfòme yo ak dispozisyon ki nan Tablo 2.
Yo ta dwe chwazi materyèl filler izolasyon an selon tanperati fonksyònman eleman an. Lè tanperati k ap travay T mwens pase oswa egal a 400 degre, ranpli poud oksid mayezyòm ba-tanperati; Lè tanperati travay la se 400 degre< t≤="" 600="" °c,="" fill="" with="" medium="" temperature="" magnesium="" oxide="" powder;="" when="" the="" working="" temperature="" is="" 600="">< t≤850="" °c,="" fill="" with="" high-temperature="" magnesium="" oxide="" powder.="" brass="" exit="" rods="" shall="" not="" be="" used="" for="" components="" with="" a="" maximum="" temperature="" above="" 450°c="" or="" temperatures="" exceeding="" 450°c="" that="" may="" be="" encountered="" during="" their="">
