48、s for gas welding, heating and cutting of metals. It applies to manual blowpipes for welding and heating with a nominal thermal power up to 32 000 kcal/h, and manual and machine cutting blowpipes with a cutting range up to 300 mm. This International Standard does not apply to air-aspirated blowpipes
49、 which are covered in ISO 9012. NOTE 1 Blowpipes with greater nominal thermal power or cutting range can also be tested in accordance with this International Standard if the test requirements are suitable. NOTE 2 For the most common fuel gases, the corresponding flow rates are given in Table A.1. NOTE 3 Examples of blowpipes are shown in Annex B, which also gives the terminology concerning these blowpipes.
