Coating application to industrial equipment and pipelines: According to Article 8.1.7 of HGJ229 \"Code for Construction and Acceptance of Anti-corrosion Engineering for Industrial Equipment and Pipelines\", the number of coating layers and their thickness should meet the design requirements, with a permissible negative error of ≤5% to be considered acceptable. 2. Painting of buildings and structures: GB50212 \"Code for Construction and Acceptance of Building Anti-corrosion Engineering\". 3. Painting of steel structures: GB50205 \"Code for Construction and Acceptance of Steel Structure Engineering\" (1) According to clause 4.11.4 of this Code, \"for outdoor coatings and indoor coatings, a negative deviation of 25μm is allowed when no specific design requirements are specified.\" 4. Coating application on the surface of steel structures: According to Article 4.4.3 of SL105-95 \"Code for Corrosion Protection of Metal Structures in Water (Irrigation and Power) Engineering\", the thickness at more than 85% of the measurement points should reach the designed thickness; for those points that do not reach the designed thickness, their minimum thickness should be no less than 85% of the designed thickness (5 measurement points per 10 m2). 5. Coating application inside oil storage tanks: GB13348 \"Electrostatic Safety Regulations for Liquid Petroleum Products\". 6. According to GB15599 \"Lightning Safety Specifications for Petroleum and Petroleum Facilities\", the surface resistivity Pr of antistatic coatings shall be ≤109Ω·m.
