Manufacturers' claims and laboratory requirements.

Hi Ashley, I welcome input from other LEEDUsers on this, but in my opinion there is nothing additional the LEED project team must document to address this Section 8 requirement. It serves as an industry guideline to the Manufacturer and/or testing agency publishing product TVOC data. Below is an excerpt- refer to this link for full details: https://www.cdph.ca.gov/programs/IAQ/Documents/cdph-iaq_standardmethod_v1_1_2010%20new1110.pdf "8 GUIDELINES FOR USE OF STANDARD METHOD AS BASIS FOR A BUILDING PRODUCT CLAIM In the past, product manufacturers have used test results as the basis for a single-attribute claim regarding one or a group of their products (i.e., a low VOC emissions product claim). Claims certification and verification organizations have also deemed to use these test results as part of their own process for substantiating manufacturers’ claims. Whenever this Standard Method for the Testing and Evaluation of Volatile Organic Chemical Emissions from Indoor Sources Using Environmental Chambers is to be used to make, certify or verify a building product claim, the following guidelines are recommended to ensure the integrity of the process."

I should support this comment. Any advisor or building engineer just and only should request evidence from the submitter of any statement of CDPH conformity that they work in compliance with these requirements. This regulation is meant to prevent from green-washing by just testing once and producing something with different emissions later. And yes this is related to the general emissions requirements, to my knowledge. You will not find something similar in the market regarding VOC content statements.

A manufacturer can state CDPH conformity if this statement complies with the guidelines in CDPH SM V1.1-2010, Section 8. A designer should request evidence from the manufacturer that this is the case (probably given by declaration). This documentation should in best case refer to all chapters within Section 8, but most important are 8.7 and 8.8. If the manufacturer makes use of an organization that certifies manufacturers' claims then this organization shall show that their statement complies with the guidelines in CDPH SM V1.-2010, Section 8, which on top of the above said, includes that the organization is accredited under ISO Guide 65 (or the successor of that old standard, now in ISO/IEC 17065).
