Standard 580 scope
This standard applies to non-condensable gas Purge Equipment for use with Low Pressure Centrifugal Liquid Chillers as defined in Section 3. This standard defines general equipment requirements, test methods and analysis techniques used to determine the performance rating for Purge Equipment that remove Non-Condensable Gases from Low Pressure Centrifugal Liquid Chillers. This Purge Equipment is typically used in conjunction with chillers which operate with at least a portion of the system below atmospheric pressure.
Standard 700 Scope
This standard establishes purity specifications for acceptability of fluorocarbon refrigerants regardless of source (new, reclaimed and/or repackaged) for use in new and existing refrigeration and air-conditioning products within the scope of AHRI. Refrigerants covered include: R-11, R-12, R-13, R-22, R-23, R-32, R-113, R-114, R-123, R-124, R-125, R-134a, R-143a, R-401A, R-401B, R-402A, R-402B, R-403A, R-403B, R-404A, R-405A, R-406A, R-407A, R-407B, R-407C, R-407D, R-407E, R-408A, R-409A, R-409B, R-410A, R-410B, R-411A, R-411B, R-412A, R-413A, R-500, R-502, R-503, R-507A, R-508A, R-508B, and R-509A.
Standard 740 scope
This standard establishes a single set of requirements for the testing and rating of capacity, speed, purge loss, and minimum purity requirements for refrigerants for refrigerant recovery/recycling equipment; whereby, equipment performance can be compared from product to product. The standard applies to equipment for recovering and/or recycling single compound refrigerants, azeotropes, zeotropic blends, and their normal contaminants from refrigerant systems.
