Emissions Standard
The international standard describing the laboratory test chamber method for determining the emission of volatile organic compounds from newly produced materials defines the framework for fabric outgassing measurements. This testing procedure, known as iso 16000-9, utilizes a controlled environmental chamber to collect organic vapours from sample materials under specified temperature and humidity conditions. It governs the initial generation phase of the emitted substances before they are collected on sorbent tubes for chemical analysis.
This initial testing phase ensures that the textile sample is analyzed in conditions simulating actual indoor usage.
Environmental Chamber
A specimen is placed inside a stainless steel chamber with a constant flow of purified air. Utilizing iso 16000-9 enables researchers to calculate the area-specific emission rate of volatile compounds from finished textiles. This calculation is essential for certifying that textile wall coverings and large-area upholstery fabrics do not degrade indoor air quality.
Textile Assessment
Mills submit synthetic materials and coated fabrics to certified laboratories for environmental chamber evaluation. Through the application of iso 16000-9, technicians can isolate the emissions of solvents used in polyurethane backing layers. This prevents the shipment of goods that could cause unpleasant odours or health complaints in retail environments.
Quality Audit
Independent laboratories issue formal test certificates showing compliance with the emission limits defined by brands. The test data are generated over a multi-day period to monitor the decay rate of the emitted organic compounds. This documentation is required by global brands before they authorize the commercial release of any synthetic furnishing textiles.
