The scope of this research is to measure water vapor transmission rates
of assemblies of pipe insulation materials with various joints and sealant
techniques. Most of the research is on various sheet and ﬁlm vapor retarding technologies that are widely used in the below ambient mechanical
insulation industry. Several low permeance materials that are used with
or without facers will also be evaluated. Consensus test methods ASTM
E96 and a modiﬁed version of European Standard EN 13469 will be used

TC 3.3, Refrigerant Contaminant Control

ASHRAE continues to support and facilitate global efforts to reduce the
detrimental effects of global warming. ASHRAE does this by supporting
research that support the use of new low GWP refrigerants. The proposed
research herein enables the AC&R systems using these low GWP refrigerants to perform effectively, efﬁciently, and reliably. In addition, proper
contamination control of moisture can extend the effective life and reduce
