Refrigeration Oil Description
- 适用范围
- First published in 1981 and reaffirmed in 1987, Standard 99 provides a uniform means of identifying particular refrigeration oils without resorting to commercial names or designations by utilizing common laboratory tests that are well recognized by those concerned with the use of the oil. This proposed revision of the standard expands its scope to include synthetic lubricants, especially those used with HFC refrigerants.
