    Title, Purpose, and Scope

    SSPC 34 to maintain and revise Standard 34 on continuous maintenance.
    Designation and Safety Classification of Refrigerants

    ANSI/ASHRAE Standard 34-2016 - Published standard. (Supersedes ANSI/ASHRAE Standard 34-2013)
    Designation and Safety Classification of Refrigerants

    1. PURPOSE

    1.1 This standard is intended to establish a simple means of referring to common refrigerants instead of using the chemical name, formula, or trade name. It establishes a uniform system for assigning reference numbers, safety classifications, and refrigerant concentration limits to refrigerants. The standard also identifies requirements to apply for designations and safety classifications for refrigerants and to determine refrigerant concentration limits

    2. SCOPE

    2.1 This standard provides an unambiguous system for numbering refrigerants and assigning composition-designating prefixes for refrigerants. Safety classifications based on toxicity and flammability data are included along with refrigerant concentration limits for the refrigerants.

    This standard does not imply endorsement or concurrence that individual refrigerant blends are suitable for any particular application
