1 Scope
This document specifies basic connection dimensions of LPG cylinder valves
(manufactured in accordance with
EN ISO 14245
and EN ISO 15995) and connectors (including pressure
regulators) to enable them to be safely connected together.
NOTE 1 Figure 1 (type G.1) to Figure 19 (type G.33) give the types of threaded outlet connections.
NOTE 2 Figure 20 (type G.50) to Figure 34 (type G.66) give the types of non-threaded outlet connections.
This document lists potentially unsafe connections where it might be possible to
connect together, but which, when connected, might not be sound or secure in some
operating conditions or orientations.
This document specifies a marking system that is intended to ensure that only valves
and connecters that are marked with the same connector type number are used in
combination.
This document also recommends tightening torques for the attachment of screwed
metal-to-metal connections.
Quality assurance systems, production testing and particularly certificates of
conformity are not covered in this document.
This document excludes connections for automotive vehicles covered by
UN/ECE Regulation No. 67 Part 1 and
EN 13760.
This document excludes connections for gas cartridges covered by
EN 417.
