This Technical Report specifies a method for the determination of ammonia from cellulose insulation products at 90% relative humidity (RH). This document is based on the existing prEN 16516 standard which provides an horizontal reference method for the determination of emissions of regulated dangerous substances from construction products into indoor air.<\/p>\n
