- ASTM系美国材料与试验协会的英文缩写，其英文全称为American Society for Testing and Materials。该技术协会成立于1898年
北京赛福莱博科技代理美国ASTM制定工业参比炭黑IRB，常备现货
炭黑物理性能测试ASTM D412 ,D3182,D3192 ,D3191用工业参比炭黑IRB (industry reference black)，zuixin标样IRB 8替代IRB7.
IRB 8与IRB7 相比，有多项不同，请见下表
ASTM 测试方法 测试项目 测试结果 D3191, Method B Carbon Black in SBR, Tensile Strength, Difference from IRB#7 -0.33 MPa (-48 psi) D3191, Method B Carbon Black in SBR, Tensile Stress at 300% Elongation, Difference from IRB#7 -0.63 MPa (-91 psi) D3191, Method B Carbon Black in SBR, Ultimate Elongation, Difference from IRB#7 5.5 % D3191, Method C Carbon Black in SBR, Tensile Strength, Difference from IRB#7 -0.16 MPa (-23 psi) D3191, Method C Carbon Black in SBR, Tensile Stress at 300% Elongation, Difference from IRB#7 -0.54 MPa (-78 psi) D3191, Method C Carbon Black in SBR, Ultimate Elongation, Difference from IRB#7 9.4 % D3192, Method B Carbon Black in NR, Tensile Strength, Difference from IRB#7 -0.03 MPa (-4 psi) D3192, Method B Carbon Black in NR, Tensile Stress at 300% Elongation, Difference from IRB#7 -0.09 MPa (-13 psi) D3192, Method B Carbon Black in NR, Ultimate Elongation, Difference from IRB#7 4.2 % D3192, Method C Carbon Black in NR, Tensile Strength, Difference from IRB#7 -0.21 MPa (-30 psi) D3192, Method C Carbon Black in NR, Tensile Stress at 300% Elongation, Difference from IRB#7 -0.36 MPa (-52 psi) D3192, Method C Carbon Black in NR, Ultimate Elongation, Difference from IRB#7 -0.2 %
标准参比炭黑 standard reference carbon black 一种具有典型物化性能、质量均匀、性能稳定的橡胶用炭黑。主要作为炭黑生产厂和橡胶制品厂验证试验重现性及再现性的标准物质。目前炭黑工业和橡胶工业常用的标准参比炭黑是ASTM SRB (standard reference black),前后推出8个系列的SRB, zuixin系列为SRB 8，IRB (industry reference black)是用于炭黑橡胶性能的工业参比炭黑，已推出IRB 1---8#，目前常用的是IRB 7 和IRB 8，国内进口商主要是北京赛福莱博科技（Safelab Tech）有限公司，ITRB (industr tint reference black)是用于炭黑着色强度测试上用的参比炭黑，名称为工业着色参比炭黑。
