1.1 Scope
This standard specifies a test method for evaluating process parameters of spray polyurethane foam (SPF) insulation, including both open-cell and closed-cell types, under controlled variations in component ratio and environmental conditions. The method assesses the effects of mix ratio, ambient temperature, processing temperature, and fluid pressure on the quality of the applied foam. It provides procedures for measuring sprayability, set-back (foam shrinkage), core density, and other physical characteristics, with continuous recording of processing parameters.
