US EPA Method 24 to be mentioned in the Datasheet

Yousef— US EPA Method 24 is the default VOC standard for US-made products. If the product is made in the United States and if the VOC is reported in grams per liter (g/L), I would say no, especially if the data sheet says, “less water and exempt compounds.” However, when I have worked with data sheets from outside the US, I have found VOC reported as a percentage by volume or in g/L, but using a different basis than that prescribed by SCAQMD Rules. If the product is made outside the United States, it might be a good idea to call the manufacturer’s non-emergency technical support number listed on their websites or on the product’s material safety data sheet. If you can reach a qualified technical representative, they should be able to confirm whether the reported measurements are compatible. Many international projects appear to have difficulties obtaining VOC data based on US regulatory standards. If your project is outside the US, it might be wise to submit a formal inquiry to the USGBC/GBCI asking for guidance clarifying which VOC standards are acceptable for use on LEED NC-2009 international projects. A definitive ruling would resolve this issue around the globe.

Did anyone ask for guidance clarifying which VOC standards are acceptable for use on LEED NC-2009 international projects? I am having similar issues trying to acquire VOC in terms of g/L. The data for Weber Saint-Gobain products, made in Turkey (Cement based tile adhesive) states: VOC (Directive 1999/13/EC) : 0 VOC (volatile carbon) : 0 Will this be accepted without measurement in terms of g/L? The material is also denoted as a hazmat with lung, skin and eye irritants. I am getting push-back from many, including the manufacturer, who states: <> Chromium 6 is a known carcinogen!! If a measurement of VOCs in terms of g/L cannot be provided, would requesting the following input be an acceptable alternative to the USGBC? 1 - A description of how the VOCs were measured, if following a EU standard or other standard 2 - A list of ALL product ingredients for both “6312-Weber.kol XL” and “6352-Weber.Joint Flex” Any input would be most appreciated. :-)
