The standards committee for welding and allied processes ( NAS ) at DIN , formerly the standards committee for welding technology, is responsible for national standardization and represents the German standardization interests at European level ( CEN ) in the CEN / TC (Technical Committee) 121 " Welding " and CEN / TC 240 " Thermal spraying and thermal sprayed layers ”as well as at the international level ( ISO ) in ISO / TC 44“ Welding and allied processes ”.

history

The NAS was founded in 1925. In 1999 the support group "Welding and Allied Processes" was founded in the NAS for financial support, to which about 112 companies, associations and institutions have joined, most of which are actively involved in the working bodies of the NAS.
