标准范围

ISO 9012:2008规定了吸气式手吹管的要求和试验方法。ISO 9012:2008适用于钎焊、钎焊、加热、熔合和其他相关热处理用的吹管，这些吹管使用燃料气和吸入空气（喷射式吹管），并用于手动使用。ISO 9012:2008适用于:在调节器控制的压力下，通过供气软管向气相燃料气供气的吸气式手吹管；通过供气软管，在容器压力下向吸气式手吹管输送气相液化燃料气；所谓的液相吹管，在液相中注入燃料气，吹管内发生热蒸发。

ISO 9012:2008 specifies requirements and test methods for air-aspirated hand blowpipes.ISO 9012:2008 applies to blowpipes for brazing, soldering, heating, fusion and other allied thermal processes, which use a fuel gas and aspirated air (injector-type blowpipes), and are intended for manual use.ISO 9012:2008 is applicable to: air-aspirated hand blowpipes which are fed with a fuel gas in the gaseous phase, at a controlled pressure by a regulator, through a gas supply hose; air-aspirated hand blowpipes which are fed with a liquefied fuel gas in the gaseous phase at the container pressure, through a gas supply hose; so-called liquid-phase blowpipes which are fed with a fuel gas in the liquid phase, and where thermal evaporation takes place within the blowpipe.
