美國ASTM 新IRB9工業標準參比炭黑（美國原裝進口）

北京冠遠科技有限公司為中國總代理：美國ASTM新制定工業參比炭黑IRB9，常備現貨

ASTM系美國材料與試驗協會的英文縮寫，其英文全稱為American Society for Testing and Materials。該技術協會成立于1898年

炭黑物理性能測試ASTM D412 ,D3182,D3192 ,D3191用工業參比炭黑IRB (industry reference black)，新標樣IRB 9替代IRB8.

IRB 9與IRB8 相比，有多項不同，請見下表

標準參比炭黑 standard reference carbon black 一種具有典型物化性能、質量均勻、性能穩定的橡膠用炭黑。主要作為炭黑生產廠和橡膠制品廠驗證試驗重現性及再現性的標準物質。目前炭黑工業和橡膠工業常用的標準參比炭黑是ASTM SRB (standard reference black),前后推出9個系列的SRB, 新系列為SRB 8，IRB (industry reference black)是用于炭黑橡膠性能的工業參比炭黑，已推出IRB 1---9#，目前新推出的是IRB9，國內進口中國總代理商主要是北京冠遠科技有限公司，ITRB (industr tint reference black)是用于炭黑著色強度測試上用的參比炭黑，名稱為工業著色參比炭黑。
