1. Scope
The practice provides detailed procedures for measuring the volatile organic compounds (VOC) emitted from spray-applied rigid polyurethane cellular plastic thermal insulation (SPPI) products under conditions designed to simulate product use as building envelope insulation in residential buildings. An initial head-space analysis is used to identify the VOC released by a SPPI specimen so that the environmental chamber chemical sampling requirements can be determined. The VOC emission rates are determined by observing airborne VOC concentrations in a small chamber under defined temperature, relative humidity, air change and product loading test conditions (ASTM D 5116). The VOC concentrations in the chamber air sample are determined by adsorption on a solid sorbent tube followed by thermal desorption and combined gas chromatography/mass spectrometry (GC/MS) or other appropriate methods (ASTM D3686, D5466, D6196, D6345). If other compounds are expected to be present, additional specific air sampling may be required.
