This part of BS 6400 is applicable to meter installations: a) supplied with 3rd family gases either: 1) from low pressure service pipework with a maximum operating pressure not exceeding 75 mbar and a design maximum incidental pressure of 350 mbar; or 2) 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. Installation pipework is specified in BS 5482-1 and LPGA Code of Practice 25 [14]. Service pipework (including the first emergency control valve) is specified in BS 5482-1 and the LPGA Code of Practice 22 [15] and LPGA Code of Practice 25 [14]. This standard does not cover pressure regulating installations installed in a service pipework upstream of the emergency control valve.

This European Standard specifies the requirements and tests for the construction, performance, safety and conformity of gas=volume electronic conversion devices associated to gas meters, used to measure volumes of fuel gases of the 1st and 2nd families according to EN 437. This European Standard is intended for type testing, the detailed relevant provisions of which are given in Annex A. Only three kinds of conversion are treated in this European Standard: - conversion as a function of temperature only (called T conversion); - conversion as a function of the pressure and of the temperature with constant compression factor ( called PT conversion); - conversion as a function of the pressure, the temperature and taking into account the compression factor (called PTZ conversion). This document is not relevant to temperature conversion integrated into gas meters which only indicate the converted volume. Gas-volume conversion devices consist of a calculator and a temperature transducer or a calculator, a temperature transducer and a pressure transducer locally installed. For application of this European Standard, a conversion device my be, as a choice of the manufacturer, considered as a complete instrument (Type 1) or made of separate elements (Type 2), according to the definitions given in 3.1.18.1 and 3.1.18.2. In this last case, the provisions concerning pressure transducers, temperature sensors and temperature transducers are given in Annexes B, C and D respectively. Any conversion device can provide an error curve correction for a gas meter. NOTE When rendering an account to an end user the readings from the conversion device can be used in conjunction with the readings from a gas meter conforming to EN 1359, EN 12480, or EN 12261, as appropriate, or to any other appropriate and relevant international standard for gas meters, without prejudice of national regulations.
