CSA Preface

This is the first edition of CSA C900.4, Heat meters - Part 4: Pattern approval tests, which is an adoption, with Canadian deviations, of the identically titled CEN (European Committee for Standardization) Standard EN 1434-4 (first edition, 1997-02), including amendment A1:2002.

1 Scope

This European Standard applies to heat meters, that is to instruments intended for measuring the heat which, in a heat-exchange circuit, is absorbed or given up by a liquid called the heat-conveying liquid. The meter indicates heat quantity in legal units.

Electrical safety requirements are not covered by this standard.

Meters with surface mounted temperature sensors are not yet included in this standard.

Part 4 specifies pattern approval tests.
