This standard is a revision of Y535—80. During the revision, the content of Y5359—89 was retained, and the technical requirements and test methods for liquid products were improved. In addition to the requirements in Appendix A of the original standard, this standard reduces the number of H and replaces Appendix 9 of SY3S9B. This additional standard was proposed and approved by the British Natural Gas Professional Standardization Committee. This standard was drafted by: Bai'an Oil Chemical Plant. Foreword
