This International Standard specifies the requirements and test methods for air-aspirated hand blowpipes.
This International Standard 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.
This International Standard 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.
It does not apply to blowpipes in which the fuel gas leaves the injector in the liquid phase, or to so-called "cartridge" blowpipes where the gas supply is fixed directly on to the blowpipe and possibly constitutes the shank.
NOTE The drawings shown in this International Standard are given for information only, to facilitate explanation of the terms. They do not specify the construction details which are left to the discretion of the manufacturer.
