This document 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 document 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 document: - 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. EN 12405-2 applies for energy conversion. 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 document, a conversion device may 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 or national standard for gas meters, without prejudice of national regulations.

This Part of EN 1366 specifies a method for determining the fire resistance of vertical and horizontal ventilation ducts including those access panels, which are integral part of the tested ducts. The test examines the behaviour of ducts exposed to fire from the outside (duct A) and fire inside the duct (duct B). This Standard is used in conjunction with EN1363-1. Annex A provides general guidance and gives background information. This European Standard is not applicable to: a) ducts whose fire resistance depends on the fire resistance performance of a ceiling or wall(where ducts are located in cavities enclosed by fire-resistant shafts or ceilings); b) ducts containing fire dampers at points where they pass through fire separations; c) one, two or three sided ducts; d) fixing of suspension devices (e.g. anchors) to floors or walls.

This part of EN 1366 specifies a method for determining the fire resistance of non-mechanical fire barriers installed in fire separating elements designed to withstand heat and the passage of smoke and gases at high temperature. This European Standard is used in conjunction with EN 1363 1 and EN 1366 2. This European Standard is not suitable for testing non-mechanical fire barriers in suspended ceilings without modification. This European Standard is not suitable for testing fire dampers, see EN 1366 2. This European Standard is not suitable for testing such products as air transfer grilles, as the pressures and flows involved are different and may cause differing behaviour.
