ÖNORM EN 1327

This European standard specifies the requirements and relevant methods of measurement and test of two types of thermoplastic hoses with maximum design working pressure of 1 MPa and 2 MPa respectively, used for flexible gas supply lines in specific fields of application as follows: small kits according to EN 1326; air-aspirated blowpipes for welding and allied processes; miniature welding such as jewellery work, dentistry work excluding acetylene applications; arc welding with shielding gas. NOTE: This standard does not exclude the use of rubber hoses in the same fields of application. Rubber hoses for these applications are covered by EN 559. This standard does not apply to hoses for liquified petroleum gases (LPGI in liquid phase and acetylene. The hose manufacturer shall be consulted for compatibility of the hose to hydrogen application.
