CS-v4.1 EQc2:Low-Emitting Materials

VOC emission test performed on a different product in the same product line

Hi LEED experts,

I'm working on a project that intends to use a Sealant, which the manufacturer claims has been tested according to California Department of Public Health (CDPH) Standard Method v1.2–2017; however, the documentation provided shows a test performed on a different product in the same product line.

The manufacturer confirms that the raw materials used in the tested product are the same as the proposed material for the project but with the highest VOC content. Therefore, it represents this product line's worst-case scenario of VOC content.

The question is: Are these test results from another product with a similar composition and higher VOC content acceptable for the Low Emitting Materials credit criteria? have you had a similar situation? 

Thank you.

I would ask the manufacturer to provide the justification, and run that by your LEED "guide" as a question. You'd probably not get a yes or no answer, so ask if the approach is acceptable.

Thank you Deborah.
