Emission Reference Method
Emission reference methods establish the European procedure for determining the release of hazardous substances from interior furnishings and construction products. Testing for en 16516 requires a climate-controlled chamber where the temperature and humidity remain constant for twenty-eight days. This standard defines the specific ventilation rates used to simulate a standard room environment.
Chamber Condition
The technical configuration of the chamber maintains the air quality to match a living environment. Air enters at a fixed rate to maintain a specific loading factor. Sensors monitor the temperature throughout the duration of the test.
Specimen Loading
Preparation of the material for testing follows strict guidelines regarding the surface area exposed to the chamber air. This en 16516 protocol requires that the edges of the sample are sealed with aluminum foil so that emissions only come from the face of the fabric. Technicians place the specimen in the center of the chamber.
Air samples are collected at specific intervals for analysis.
Regulatory Compliance
Compliance with this standard is a requirement for many green building certifications and indoor air quality labels. Manufacturers submit samples of carpets and curtains to accredited laboratories for verification. A passing result indicates that the formaldehydes and other organic emissions are below the safety threshold.
This documentation allows the product to enter markets with strict environmental laws.
