Full Description

ASHRAE Standard 41.4 prescribes a method for measuring the proportion of lubricant in liquid refrigerant. The methods used apply to all lubricant-refrigerant combinations. The primary method used is the gravimetric method, but alternative methods are permitted if calibrated against the primary method. The standard does not apply to collected samples that contain less than 0.001 g (0.015 grains) of lubricant.

This is a 2025 reaffirmation of the 2015 edition of the standard.
