Standard 34-2007, Designation and Safety Classification of Refrigerants (ANSI  Approved)
(Packaged with Standard 15-2007, Safety Standard for Refrigeration Systems [ANSI Approved])

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 also establishes a uniform system for assigning reference numbers and safety classifications to refrigerants. The standard identifies requirements to apply for designations and safety classifications for refrigerants, including blends, in addenda or revisions to this standard.
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. This standard
does not imply endorsement or concurrence that individual refrigerant blends are suitable for any particular application.

Standard 15-2007, Safety Standard for Refrigeration Systems (ANSI Approved)

This standard specifies safe design, construction, installation, and operation of refrigeration systems. It also establishes safeguards for life, limb, health, and property, and prescribes safety requirements.
This standard applies (a) to the design, construction, test, installation, operation, and inspection of mechanical and absorption refrigeration systems, including heat pump systems used in stationary applications, (b) to modifications including replacement of parts or components if they are not identical in function and capacity, and (c) to substitutions of refrigerant having a different designation.
