Organization: ASHRAE
Publication Date: 23 June 2007
Status: active
Page Count: 16
scope:

This standard describes the preparation of sealed glass tubes and the procedure for charging them with refrigerant, lubricant, other materials to be tested, or combinations of these.

A procedure for aging the tubes, usually at elevated temperatures, is described. The tubes are evaluated by quantitative or qualitative analysis, or both, of the tube contents to yield information for determining the compatibility or chemical stability of materials in refrigerant systems.

The technique described may be used for evaluating many different types of materials. Therefore, the standard does not describe in detail the preparation of the materials to be tested prior to placing them in the glass tubes, the conditions of exposure, nor the methods of analysis.

Detailed safety precautions are included in Section 8, "Safety Requirements."

PURPOSE

The purpose of this standard is to establish a test procedure utilizing sealed glass tubes for the evaluation of materials for use in refrigerant systems.
