DIN EN ISO 9539:2014-04

This International Standard specifies the general, and some of the special, requirements on materials used for the construction of equipment used in gas welding, cutting and allied processes. Additional requirements on materials for some equipment are given in other standards. This International Standard is not applicable to materials used for the construction of welding hoses which are specified in ISO 3821. The amendment included in this document corrects the wording of clause 4.2.1 of DIN EN ISO 9539:2010-05, which can be interpreted in two ways. It was not clear if there shall be a measurement after test steps a), b) and c) respectively or if there shall be only one measurement after test step c). With this amendment a clear procedure is given.
