    Product Details

    • Preface/Scope

    Preface


    This is the seventh edition of CSA Standard 852 (now CAN/CSA-852), Mechanical Refrigeration Cade. It supersedes previous editions published in 1939, 1951, 1965, 1977, 1983, and 1991.


    It should be understood that this is a recommended Standard only and does not have the force of law until adopted officially by the various jurisdictions; also, that the regulatory authorities having jurisdiction, even though having adopted it, should be consulted as to the extent of such adoption, as the Code may have been adopted with exemptions or with additional requirements.


    In the preparation of this new edition, the refrigerant classification system in the 1991 edition was reviewed to bring it in line with the system adopted in the new edition of ANSI/ASH RAE Standard 34. The recent changes in ANSI/ASHRAE Standard 15, Safety Cade far Mechanical Refrigeration, were also reviewed when preparing the revisions to this edition made necessary by the use of new refrigerants and the new classification system.


    This Standard was prepared by the Technical Committee on Mechanical Refrigeration Code under the jurisdiction of the Standards Steering Committee on Public Safety and was formally approved by these Committees. It has been approved as a National Standard of Canada by the Standards Council of Canada.


    Scope

    1.1.3

    This Standard applies to all refrigerating systems installed subsequent to its adoption and to parts replaced in or added to systems installed prior or subsequent to its adoption.
