Standards Development

Scope

This document specifies normative references, terms and definitions, rating requirements, published rating, tolerance, and marking provisions of positive displacement refrigerant compressors. This standard applies to positive displacement refrigerant compressors and their presentation of performance in air-conditioning, heating, refrigeration, and dehumidification applications. Single stage, two-stage, and refrigerant-injected compressors without intermediate temperature load (only one evaporator) are included in this standard. Subcritical operation and transcritical operation are included in this standard.Compressors for other applications, compression types, and operations can also refer to this standard.

The manufacturer is solely responsible for the determination of values to be used in the published product information.

This standard is intended for the guidance of the industry, including manufacturers, engineers, installers, and service contractors. It defines the minimum amount of information, in a standard form to enable the evaluation and comparison of different compressors for use in an application.
