1、Designation:D617819Standard Practice forEstimation of Short-Term Inhalation Exposure to VolatileOrganic Chemicals Emitted from Bedding Sets1This standard is issued under the fixed designation D6178;the number immediately following the designation indicates the year oforiginal adoption or,in the case
2、 of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This practice describes the procedures for estimation ofshort-term human inhalation exposure to vo
3、latile organiccompounds(VOCs)emitted from bedding sets when a newbedding set is first brought into a bedroom.1.2 The estimated exposure is based on an estimated emis-sion profile of VOCs from bedding sets.1.3 The VOC emission from bedding sets,as in the case ofother household furnishings,usually are
