American Society of Heating, Refrigerat-ing and Air Conditioning (ASHRAE), Atlanta, is seeking members to develop two standards related to test methods.

SPC 173P, "Method of Test to Determine the Performance of Halocarbon Refrigerant Leak Detectors," will establish methods to test these devices. Efforts to limit greenhouse gas emissions have focused on chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs), but limiting hydrofluorocarbon (HFC) emissions are a high priority due to the Kyoto Protocol. Committee chair Denis Clodic believes that even though efforts have been made in the last 10 years, leak tightness control is not well established in the refrigerating and air-conditioning industries.

Members also are being sought for SPC 172P, "Method of Test for Insoluble Materials in Synthetic Lubricants and HFC Refrigerant Systems." The test will determine the presence of materials that separate from refrigerant and lubricant mixtures over a range of temperatures and concentrations.

Persons interested in serving on a committee should contact ASHRAE's manager of standards at (404) 636-8400, ext. 507; fax (404) 321-5478; e-mail
