Abstract

BS 6400-3:2007 Specification for installation, exchange, relocation and removal of gas meters with a maximum capacity not exceeding 6 m3/h. Low and medium pressure (3rd family gases) BS 6400-3 specifies requirements for the installation, exchange, relocation and removal of credit or prepayment diaphragm and ultrasonic gas meters with a maximum capacity not exceeding 6 m³/h. This part of BS 6400 is applicable to meter installations: a) Supplied with 3rd family gases either:

From low pressure service pipework with a maximum operating pressure not exceeding 75 mbar and a design maximum incidental pressure of 350 mbar
From medium pressure service pipework with a maximum operating pressure exceeding 75 mbar but not exceeding 2 bar and a design maximum incidental pressure of 2.7 bar. b) Only fitted downstream of the emergency control valve c) That utilizes a meter regulator downstream of the emergency control valve d) Where all gas fittings subjected to medium pressure have been pre-assembled and where strength and gas tightness testing has been undertaken on the regulator assembly at the factory e) Where the operating pressure at the outlet of the meter is nominally 37 mbar. Also available: BS 8499:2017 Specification for domestic gas meter boxes and meter bracket
