1. Scope
1.Scope 1.1.This practice is intended for fast, qualitative and semi-quantitative screening of vapor-phase organic compounds (volatiles and some semi-volatiles) released from materials under simulated real use conditions using micro-scale test chambers. In principle, it can be applied to most building products, consumer goods and vehicle interior trim materials. In the case of dry, homogeneous materials; results from tests of volatile organic emissions carried out using micro-scale chambers on newly manufactured products have been found to correlate well with data obtained using standard (reference) methods and conventional emission test chambers or cells (D-6670, D-5116 and D-7143).1-3 This practice is therefore complementary to existing standards and provides third party test laboratories and manufacturing industry with a cost-effective approach for: monitoring VOC emissions as part of routine quality control monitoring product uniformity / conformity in-between formal certification tests comparing emissions from products within a range (e.g. different colors / patterns) evaluating prototype, low-emission materials/products during development By fulfilling these functions micro-scale test chambers should encourage more in-house testing of emissions thus helping ensure consumer safety and promoting the development of low emission products and materials. Micro-scale chambers have also been shown to facilitate better recovery of semi-volatile organic vapors when compared with conventional small test chambers or cells.1,4 This practice describes the design, construction, performance, evaluation and use of micro-scale chambers for testing vapor-phase organic emissions. Information on sampling, transport and storage of materials to be tested, and on preparation of test specimens, is available in other relevant standards and is referenced.
