We have an adhesive manufacturer claiming that they have complied with the Low-Emitting Materials testing requirements by undertaking CARB Method 310 tests on their product to determine the percent VOC content. While the guide is clear that the accepted methods for testing are only EPA Method 24 and SCAQMD 304, the manufacturer is promoting Method 310 on the basis that one of the tests incorporated within Method 310 is based on EPA Method 24 (see section 3.3.1 in the Method 310 Guide).

If the percent VOC content is indeed tested using Method 310 and found to be 0%, is it acceptable for LEED to conclude that the VOC content is 0 g/L and the product will be approved?

Thank you.
