ASTM A871 / A871M ibyuma

Ibisobanuro bya ASTM A871 nibisanzwe byerekana imbaraga zifite imbaraga nke-zidafite ibyuma byubaka ibyuma bifite ibyuma birwanya ruswa byangiza ikirere bikoreshwa mubyuma na pole. Icyiciro cya 60 na 65 birahari muburyo bwo kuzunguruka, bisanzwe, cyangwa kuzimya no kugabanura ibintu nkuko bisabwa kugirango ugere kumiterere yihariye.

Ibisobanuro:
Umubyimba: 3mm - 150mm
Ubugari: 30mm - 4000mm
Uburebure: 1000mm - 12000mm
Bisanzwe: ASTM EN10025 JIS GB

A871 Icyiciro cya 65 gishobora gutangwa nkizunguruka, gisanzwe cyangwa kizimye kandi gifite ubushyuhe.
