CDPH/EHLB Std. Method V1.2, 2017

Document Title:  Standard Method for the Testing and Evaluation of Volatile Organic Chemical Emissions from Indoor Sources Using Environmental Chambers, Version 1.2
Developer:  California Department of Public Health
Summary of Scope:  The CDPH Standard Method is the primary VOC emissions standard for North America.  It is required by USGBC for LEED v4, EQ: Low-Emitting Materials testing of interior building products used on floors, walls and ceilings.  It is used for the FloorScore® certification program for hard surface flooring and is referenced by many other programs and building standards.  This new version of the standard was published by CDPH in January 2017.  It updates the allowable concentration for benzene emissions in Table 4-1 to 1.5 µg/m3.  The revision was based on a downward revision of the benzene chronic REL from 60 to 3 µg/m3 made by OEHHA in 2014.  The change in the allowable benzene concentration became effective on April 1, 2017.  All other requirements of the standard are unchanged from V1.1.  Supercedes CDPH/EHLB Standard Method V1.1, 2010.
