Some standards have now been updated, and the original standards are no longer in use. I have a few new standards for which I cannot find the original texts; I hope everyone can help out. Thank you! YB/T 5075-2005 \"Coal Tar\"; YB/T 5022-2005 \"Crude Benzene\"; GB/T 3715-2007 \"Terms Related to Coal Quality and Coal Analysis\"; YB/T 5079-2005 \"Crude Phenol\"; YB/T 5174-2005 \"Raw Oil for Carbon Black Production\".
