scope:

This guideline provides a means by which colors can be assigned to refrigerant containers for Refrigerants currently in use or newly developed Refrigerants, provided the Refrigerant is used in significant quantities as defined in this guideline. Colors should not be relied upon exclusively to determine the type of Refrigerant in the container.

This guideline also recommends a container color for Refrigerants that are not produced in sufficient quantities to qualify for their own individual color.

Purpose. The purpose of this guideline is to establish assignment of refrigerant container colors; definitions; basic considerations for developing the color guideline; and assignment criteria.
