PD CEN/TR 17304 is a European standard on construction products that discusses the assessment of the release of dangerous substances for construction products.
PD CEN/TR 17304 specifies a method for the determination of emissions of ammonia from cellulose insulation products into indoor air at 90% relative humidity (RH). It is based on the use of an emission test chamber and subsequent analysis of ammonia in test chamber air.
PD CEN/TR 17304 on the determination of emissions into the indoor air is relevant to:
The presence in the environment of chemicals originating from construction products underlines the need for a prospective assessment of such products. The aim of this publication is to give an overview of the current methodologies for assessing the release of potentially hazardous substances from construction products.
PD CEN/TR 17304 specifies the horizontal reference method for testing the emission (release) of dangerous substances from construction products into indoor air. PD CEN/TR 17304 uses a test chamber in which emissions are generated under conditions that are kept constant during the test.
As a user of PD CEN/TR 17304, you are provided with guidance regarding the dimensions of the test specimen, ventilation, air velocity, cleanliness of test chamber, testing climate, storage of test specimen, the volume of test chamber and placement of test specimen in a test chamber. In this manner, you can conduct the assessment process efficiently and accurately.
