In this article, two standards of SY/T 0315—2013 and SY/T 0315—2005 were compared from inspection organization qualification, inspection items, performance requirements, etc. The results indicated that in SY/T 0315—2013 standard, it requires coating, coating quality qualification and technology test should be done by the third party inspection organization with qualification. The epoxy powder sampling inspection number was increased by 67%. It increased some inspection items, such as the degree of dust level, glass transition temperature values, 28 d adhesive and cathodic disbondment test. The cathodic disbondment test conditions and performance indicators of 24 h and 28 d were adjusted. Some measures and precautions were put forward during SY/T 0315—2013 standard executing process.
