VOC questions: Testing method and translation

I have a product from a large paint corporation, that has manufacturer information that supports the VOC content in g/L. They have made this with the manufacturer's own laboratory, but it's not from a third-party organization, and I don't know what's the testing procedure made by the laboratory. This manufacturer technical sheet is enough for LEED. Othe question. Most of our products come from mexican companies and we have technical specifications and MSDS in spanish. Should we need to translate all the document, or we could integrate them in spanish in a pdf and make a narrative in English that translates the relevant parts?
