This British Standard specifies requirements for gas meter boxes for use with single gas meter installations conforming to BS6400, which: are supplied with gases of the 2nd and 3rd family, with a maximum capacity of 6 m3/h and a maximum operating pressure not exceeding 2 bar; and incorporate any of the following meters: diaphragm, ultrasonic, credit or prepayment. It does not apply to multiple meter installations which are installed in the same housing. NOTE1 The composition of fuel gases of the 2nd and 3rd family is specified in BSEN437. NOTE2 All pressures quoted in this standard are gauge pressures. It covers the following designs of meter box, including any associated box extensions: built-in; surface mounted; semi-concealed; universal. It does not cover security shrouds intended to provide additional protection to meter installations. This British Standard also specifies requirements for the design of the standard meter bracket.
