Standard 15-2007 – Safety Standard for Refrigeration Systems (ANSI Approved): This standard specifies safe design, construction, installation, and operation of refrigeration systems. This standard establishes safeguards for life, limb, health, and property and prescribes safety requirements. This standard applies to a. 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. |

ANSI/ASHRAE Standard 34-2007: Revisions to ASHRAE’s Standard 34 should make it easier for manufacturers to prepare applications for refrigerant number assignment and safety classification. ANSI/ASHRAE Standard 34-2007, Designation and Safety Classification of Refrigerants, establishes a simple means of referring to common refrigerants in place of chemical names, formulas or trade names. It also establishes safety classifications based on toxicity and flammability data. The 2007 standard contains a total of 16 new refrigerants. The new standard contains revisions to the flammability classification and details on the flammability and fractionation testing procedures. These should make it easier for manufacturers to prepare applications for refrigerant number assignment and safety classification, according to Bill Walter, Standard 34 committee chair. In addition, a new section has been added specifying the criteria to determine recommended refrigerant concentration limits (RCL) in occupied spaces. The addition of RCL values will be useful in application of the refrigerants in the field. "In general, incorporating the 23 approved addenda into one document makes the standard easier to read and understand, making it easier for users to determine the current requirements to get a refrigerant listed in the standard," Walter said. |
