I don't know if anyone has faced this dilemma before, but for me I'm sick and tired of it.  Certain manufacturer sites have products with a "less than or <" VOC content instead of a solid number for content.  In the past I have asked the general contractor to follow up with his vendors to find a product sheet with an ACTUAL VOC number in g/L, but they usually respond with "that's how the manufacturer lists their VOC content and there's nothing more we can do".  To which then I have to gamble with adding a value that is one number less than VOC content.  In other words, if the product has "less than or < 50 g/L", I put 49 g/L in the Low-Emitting Materials calculator.

Do I just add a number below below the limit the product states or do I still hound the general contractor endlessly for some other way to pull out an actual VOC value in g/L?
