I'm having difficulties to understand the difference between the VOC emission requirements and the VOC content requirements as stated in the LEED-draft. When the MSDS of a adhesive or sealant mentions that it has a VOC of for example 50 g/L, and the limit is 100 g/L, is this enough for the product to be LEED-compliant? Or are more specifications necessary about the testing methods of the company? In other words, Is it possible for a company to just state that the VOC-level is lower than the limit, or does it have to pay for it at official testing bureaus (like Eurofins) to be official LEED-compliant.

Since it is becoming more and more popular outside of the USA (I'm from Europe), I'd have to know more about LEED.
