【国外标准】 Standard Practice for Determining Emission Profiles of Volatile Organic Chemicals Emitted from Bedding Sets

5.1 The objective of this practice is to provide procedures for estimating emission profiles of VOCs from bedding sets. These profiles can then be used to estimate human inhalation exposures to VOCs emitted from bedding sets. The estimated inhalation exposures ultimately can be used as an input to characterization of health risks from short–term VOC exposures.5.2 The results of emissions testing for specific raw materials and components, or processes used in manufacturing different bedding sets, can be used to compare their relative impacts on airborne concentrations.1.1 This practice covers the procedures for estimating emission profiles of volatile organic chemicals (VOCs) from bedding sets when a new bedding set is first brought into a house, based on emissions testing in environmental chambers.1.2 Emission profiles from bedding sets are determined from air concentrations measured in environmental chambers.1.3 VOC emissions from bedding sets, as in the case of other household furnishings, usually are highest when the products are new. Procedures described in this practice also are applicable to used bedding sets.1.4 The practice is applicable to VOCs and not to semi-volatile organic chemicals or nonvolatile organic chemicals.1.5 This practice summarizes procedures for sample selection and handling. This practice also refers to pertinent sampling procedures and analytical methods for emission testing, but does not include technical details on selection of appropriate collection media and analytical methods or on sampling and analytical equipment and associated procedures.1.6 Emission profiles based on this practice may be used for estimating human exposures to VOCs.1.7 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.8 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.9 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
