ASTM系美國材料與試驗協(xié)會的英文縮寫,其英文全稱為American Society for Testing and Materials。該技術(shù)協(xié)會成立于1898年。
炭黑物理性能測試ASTM D412 ,D3182,D3192 ,D3191用工業(yè)參比炭黑IRB (industry reference black),標(biāo)樣IRB 9替代IRB8.
標(biāo)準(zhǔn)參比炭黑 standard reference carbon black 一種具有典型物化性能、質(zhì)量均勻、性能穩(wěn)定的橡膠用炭黑。主要作為炭黑生產(chǎn)廠和橡膠制品廠驗證試驗重現(xiàn)性及再現(xiàn)性的標(biāo)準(zhǔn)物質(zhì)。目前炭黑工業(yè)和橡膠工業(yè)常用的標(biāo)準(zhǔn)參比炭黑是ASTM SRB (standard reference black),前后推出9個系列的SRB, 系列為SRB 8,IRB (industry reference black)是用于炭黑橡膠性能的工業(yè)參比炭黑,已推出IRB 1---9#,目前推出的是IRB9。
