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.

5.1 The objective of this practice is to provide procedures for estimation of human inhalation exposure to VOCs emitted from bedding sets in homes. The estimated inhalation exposure can be used as an input for characterization of health risks from short-term VOC exposures.5.2 The results of exposure estimation for specific raw materials and components, or processes used in manufacturing different bedding sets, can be used to compare their relative impacts on exposures.1.1 This practice describes the procedures for estimation of short-term human inhalation exposure to volatile organic compounds (VOCs) emitted from bedding sets when a new bedding set is first brought into a bedroom.1.2 The estimated exposure is based on an estimated emission profile of VOCs from bedding sets.1.3 The VOC emission from bedding sets, as in the case of other household furnishings, usually are highest when the products are new. Procedures described in this practice are applicable to both new and used bedding sets.1.4 Exposure to airborne VOC emissions in a residence is estimated for a household member, based on location and activity patterns.1.5 The estimated exposure may be used for characterization of health risks that could result from short-term exposures to VOC emissions.1.6 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.7 This standard does not purport to address all of the safety concerns, if any, associated with its use.

5.1 The objective of this guide is to describe procedures and data sources for conducting risk characterization of acute inhalation exposure to chemicals emitted from bedding sets. Risk characterization can be used to identify chemical(s) that pose potentially significant human health risks for the scenario(s) and population(s) selected for exposure assessment. Such identification of chemicals can help in identifying the components or materials used in the manufacture of bedding sets that should be further examined. Risk characterization also includes an assessment of potential odors associated with individual chemicals emitted by the bedding set.1.1 This guide describes procedures for conducting risk characterization of exposure to volatile organic chemicals (VOCs) emitted from bedding sets or an ensemble of a mattress and supporting box spring.1.2 This guide is for risk characterization of short-term exposures to a new bedding set brought into a residential indoor environment. The risk characterization considerations presented in this guide are applicable to both the general population and sensitive subgroups, such as convalescing adults.1.3 The risk characterization addressed in this guide is limited to acute health and irritation effects resulting from short-term exposure to VOCs in indoor air. Although certain procedures described in this guide may be applicable to assessing long-term exposure, the guide is not intended to address cancer and other chronic health effects.1.4 VOC emissions from bedding sets, as in the case of other household furnishings, usually are highest when the products are new. A used bedding set may also emit VOCs, either from the original materials or as a result of its use. The procedures presented in this guide also are applicable to used bedding sets.1.5 Risk characterization procedures described in this guide should be carried out under the supervision of a qualified toxicologist or risk assessment specialist, or both.1.6 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.7 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.1.8 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.
