This information was gleaned from Eurocarb. When I originally created this page on 2006 January 12, I meticulously recreated the table of values from a very difficult to read original image. Mistakes were definitely present as the original image was of poor quality. Here is a link to the original image in case you would like to scrutinize any particulars.

On 2015 July 10 I noted that Eurocarb had greatly improved the quality of these specifications. I've updated the specification with accurate information as provided by Eurocarb.
