Canadian Standards Association (operating as “CSA Group”), under whose auspices this National Standard has been produced, was chartered in 1919 and accredited by the Standards Council of Canada to the National Standards system in 1973. It is a not-for- profit, nonstatutory, voluntary membership association engaged in standards development and certification activities.

CSA Group standards reflect a national consensus of producers and users — including manufacturers, consumers, retailers, unions and professional organizations, and governmental agencies. The standards are used widely by industry and commerce and often adopted by municipal, provincial, and federal governments in their regulations, particularly in the fields of health, safety, building and construction, and the environment.

Individuals, companies, and associations across Canada indicate their support for CSA Group’s standards development by

volunteering their time and skills to Committee work and supporting CSA Group’s objectives through sustaining memberships. The more than 7000 committee volunteers and the 2000 sustaining memberships together form CSA Group’s total membership from which its Directors are chosen. Sustaining memberships represent a major source of income for CSA Group’s standards development activities.

CSA Group offers certification and testing services in support of and as an extension to its standards development activities. To ensure the integrity of its certification process, CSA Group regularly and continually audits and inspects products that bear the

CSA Group Mark.

In addition to its head office and laboratory complex in Toronto, CSA Group has regional branch offices in major centres across Canada and inspection and testing agencies in eight countries. Since 1919, CSA Group has developed the necessary expertise to meet its corporate mission: CSA Group is an independent service

organization whose mission is to provide an open and effective forum for activities facilitating the exchange of goods and services through the use of standards, certification and related services to meet national and international needs.

Thermal energy meters — Part 4: Pattern approval tests

(EN 1434-4:2015+A1:2018, MOD)

CSA Preface

This is the third edition of CSA C900.4, Thermal energy 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 (edition 3:2015 consolidated with Amendment 1:2018). It supersedes the previous edition, published in 2013 as CAN/CSA-C900.4 (adopted EN 1434-4:2007), Heat meters — Part 4: Pattern approval tests.

For brevity, this Standard will be referred to as “CSA C900.4” throughout.

This Standard is one of a group of Standards on Thermal energy meters being adopted by CSA Group, which consists of the following:

1. CSA C900.1 (adopted EN 1434-1) — Part 1: General requirements;

2. CSA C900.2 (adopted EN 1434-2) — Part 2: Constructional requirements;

3. CSA C900.3 (adopted EN 1434-3) — Part 3: Data exchange and interfaces;

4. CSA C900.4 (adopted EN 1434-4) — Part 4: Pattern approval tests;

5. CSA C900.5 (adopted EN 1434-5) — Part 5: Initial verification tests; and

6. CSA C900.6 (adopted EN 1434-6) — Part 6: Installation, commissioning, operational monitoring and maintenance.

This Standard is considered suitable for use for conformity assessment within the stated scope of the Standard.

This Standard was reviewed for Canadian adoption by the CSA Technical Committee on Thermal Energy Meters, under the jurisdiction of the CSA Strategic Steering Committee on Fuels and Appliances, and has been formally approved by the Technical Committee.

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.

1. Scope

   
   

   This European Standard specifies pattern approval 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.
