This document lists the different valve stem to gas cylinder connection threads currently and historically existing worldwide and provides official coded designations for them. These coded designations will then be available for identification and marking purposes. It also gives guidance concerning which threads are dimensionally identical and which are interchangeable. Furthermore, this document provides guidance for valving procedures when fitting valves to gas cylinders.

This document lists the terms and definitions for use in European Standards produced by CEN/TC 286.

This Part of this European Standard specifies requirements for the design of unfired pressure vessels covered by EN 13445-1:2009 and constructed of steels in accordance with EN 13445-2:2009. EN 13445-5:2009, Annex C specifies requirements for the design of access and inspection openings, closing mechanisms and special locking elements. NOTE This Part applies to design of vessels before putting into service. It may be used for in service calculation or analysis subject to appropriate adjustment.
