ASTM B193導(dǎo)電體材料電阻率的標(biāo)準(zhǔn)試驗(yàn)方法—適用范圍
Scope:
This test method covers the determination of the electrical resistivity of metallic electrical conductor material. It provides for an accuracy of 60.30 % on test specimens having a resistance of 0.00001 ? (10 μ?) or more. Weight resistivity accuracy may be adversely affected by possible inaccuracies in the assumed density of the conductor
