Preface:

This is the third edition of CSA C900.5, Thermal energy meters — Part 5: Initial verification tests, which is an adoption, with Canadian deviations, of the identically titled CEN (European Committee for Standardization) Standard EN 1434-5 (edition 3:2015 consolidated with Amendment 1:2019). It supersedes the previous edition published in 2013 as CAN/CSA-C900.5 (adopted EN 1434-5:2007), Heat meters — Part 5: Initial verification tests.

This Standard is one of a group of Standards on Thermal energy meters being adopted by CSA Group, which consists of the following:
a) CSA C900.1 (adopted EN 1434-1) — Part 1: General requirements;
b) CSA C900.2 (adopted EN 1434-2) — Part 2: Constructional requirements;
c) CSA C900.3 (adopted EN 1434-3) — Part 3: Data exchange and interfaces;
d) CSA C900.4 (adopted EN 1434-4) — Part 4: Pattern approval tests;
e) CSA C900.5 (adopted EN 1434-5) — Part 5: Initial verification tests; and
f) CSA C900.6 (adopted EN 1434-6) — Part 6: Installation, commissioning, operational monitoring and maintenance.

This Standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group.

Scope:

This European Standard specifies initial verification tests for thermal energy meters. Thermal energy meters are instruments intended for measuring the energy which in a heat-exchange circuit is absorbed (cooling) or given up (heating) by a liquid called the heat-conveying liquid. The thermal energy meter indicates the quantity of heat in legal units.

Electrical safety requirements are not covered by this European Standard.

Pressure safety requirements are not covered by this European Standard.

Surface mounted temperature sensors are not covered by this European Standard.

This standard covers meters for closed systems only, where the differential pressure over the thermal load is limited. See more
