Safety Standard for Refrigeration Systems
ASHRAE Standing Standard Project Committee 15

Committee Documents.

ASHRAE staff maintain a Basecamp folder for ASHRAE SSPC15 to store committee documents including drafts of addenda in development, calculators used to create tables provided in the standard, and interim research updates. 

Only voting members of SSPC15 have access to the Basecamp folder. To obtain access, please contact SSPC15 staff liaison Ryan Shanley and SSPC15 chair Greg Scrivener.  

Interested parties can apply to become a member of SSPC15 here. ASHRAE SSPC15 follows ANSI Essential Requirements and maintains balance between interest categories in the project committee. Therefore, an application to the project committee does not assure membership.

User's Manual.   

No User's Manual is available for the 2024 editions of ASHRAE Standard 15 and ASHRAE Standard 15.2. The last user's manual was published as a companion document to the 2001 edition of ASHRAE Standard 15. SSPC15 is considering publication of a revised edition of the user's manual to accompany the current edition of the standard and is gauging user interest in a User's Manual.  

The User’s Manual clarifies the intent of the Standard and provides an explanation of the rationale of its prohibitions and requirements. It eases use of the standard by including illustrations and examples of accepted industry practice, as well as explanations of and supporting references for formulas in the Standard.
