DIN EN ISO 25760:2015-04

DIN EN ISO 25760 is intended for suppliers, operators in testing facilities, operators performing cylinder maintenance and any person authorized to remove valves from gas cylinders. It details procedures for the safe removal of valves from cylinders and includes techniques for the identification of inoperable valves. Only the risks due to gas and gas mixtures under pressure are addressed; other technical issues relating to the removal of a valve from a cylinder are not covered. Specialized equipment and procedures are in use in parts of the gas industry to safely remove cylinder valves from low pressure gas cylinders while under pressure, for example liquefied petroleum gas (LPG); these techniques are not included in this standard. The standard is intended as a supplement to the existing national specifications for dealing with gas under pressure. The given techniques have been proven successful over years in gas industry; the application of the standard basically does not relieve the user from complying with legal requirements. This document represents the national adoption of the already published standard ISO 25760:2009. The committee responsible for this standard is NA 016-00-03 AA "Druckgasflaschen und Ausrüstung; Spiegelausschuss zu CEN/TC 23 und ISO/TC 58" ("Transportable gas cylinders and equipment; National mirror committee to CEN/TC 23 and ISO/TC 58") at DIN.
