ASTM D 4814 is 25 pages and a copy costs $59. Not priced for the curious GasBuddy reader, but then I spent $50 for the OEM service manual for a 1992 Nissan Sentra to read it as a description of a technological product. I was not disappointed by their extensive and thorough explanation. You definitely got your $50 worth of reading on that one. I even used it to fix my Sentra once, probably saved enough money to pay for it.
