“This European Standard specifies the requirements and tests for the construction, performance, safety and
production of class 1,5 mechanical diaphragm gas meters (hereinafter referred to as meters) having co-axial
single pipe, or two pipe connections, used to measure volumes of fuel gases of the 1st, 2nd and 3rd families
according to EN 437, at maximum working pressures not exceeding 0,5 bar and maximum actual flow rates
not exceeding 160 m /h over a minimum ambient temperature range of -10 °C to + 40 °C and a gas
temperature range as specified by the manufacturer with a minimum span of 40 K.
"This standard applies to meters with and without built-in mechanical temperature conversion that are installed
in locations with vibration and shocks of low significance and in
• closed locations (indoor or outdoor with protection as specified by the manufacturer) with condensing
or with non-condensing humidity

or, if specified by the manufacturer,
• open locations (outdoor without any covering) with condensing humidity or with non-condensing
humidity
and in locations with electromagnetic disturbances.
" This standard does not cover meters with electronic indexes.
"Unless otherwise stated, all pressures given in this document are gauge pressure.
"Clauses 1 to 9 and annexes B and F are for design and type testing only.

" NOTE Mechanical meters are not susceptible to electromagnetic interference and are therefore suitable for
