标准摘要
[中文适用范围]: 本文件规定了用于焊接、切割和相关工艺的橡胶软管(包括双软管)的要求。 本文件规定了正常负荷 2 MPa (20 bar) 和轻型负荷的橡胶软管的要求 [仅限于最大工作压力为 1 MPa (10 bar) 且孔径不超过 6.3 mm 的软管]。 本文件适用于在 −20 °C 至 +60 °C 温度下工作的软管,并用于: ——气焊和切割; ——惰性气体或活性气体保护下的电弧焊; ——与焊接和切割相关的工艺,特别是加热、钎焊和金属化。 本文件没有规定软管组件的要求; ISO 8207 中对此进行了详细说明。 本文件既不适用于热塑性塑料软管,也不适用于用于高压 [>0.15 MPa (>1.5 bar)] 乙炔的软管。 [外文原描述]: This document specifies requirements for rubber hoses (including twin hoses) for welding, cutting and allied processes. This document specifies requirements for rubber hoses for normal duty of 2 MPa (20 bar) and light duty [limited to hoses for maximum working pressure of 1 MPa (10 bar) and with bore up to and including 6,3 mm]. This document applies to hoses operated at temperatures −20 °C to +60 °C and used in: — gas welding and cutting; — arc welding under the protection of an inert or active gas; — processes allied to welding and cutting, in particular, heating, brazing, and metallization. This document does not specify requirements for hose assemblies; these are detailed in ISO 8207. This document applies neither to thermoplastics hoses nor to hoses used for high pressure [>0,15 MPa (>1,5 bar)] acetylene.
