2. Normative References The following documents are essential for the application of this document. For dated references, only the dated version applies to this document. For undated references, the latest edition (including all amendments) applies to this document. GB/T 265 Petroleum Products Kinematic Viscosity Determination Method and Dynamic Viscosity Calculation Method GB/T 3142 Determination of bearing capacity of lubricants (four-ball method) GB/T 3536 Determination of Flash Point and Fire Point of Petroleum Products (Cleveland Open Cup Method) GB/T 4756 Petroleum liquid manual sampling method GB/T 17040 Determination of Sulfur Content in Petroleum and Petroleum Products (Energy Dispersive X-ray Fluorescence Spectrometry) SH/T 0164 Petroleum Products Packaging, Storage and Delivery Acceptance Rules SH/T 0195 Lubricating oil corrosion test method NB/SH/T 0929 Determination of chlorine content in lubricating oil (inductively coupled plasma emission spectrometry) ASTM D5185 Standard Test Method for Multielement Determination of Used and Unused Lubricants and Base Oils by Inductively Coupled Plasma Atomic Emission Spectroscopy (ICP-AES) 3. Experiment Method 1) Kinematic viscosity Measure according to GB/T 265. 2) Flash point Measure according to GB/T 3536. 3) Maximum non-seize load PB value Measure according to the provisions of GB/T 3142. 4) Corrosion test Measure according to SH/T 0195. 5) Sulfur content Measure according to GB/T 17040. 6) Chlorine content Measure according to NB/SH/T 0929. 7) Phosphorus content Measured as specified in ASTM D5185. 4.Testing Regulations 1) Inspection classification and inspection items 2) Factory inspection Factory batch inspection items include: kinematic viscosity, flash point, PB value of maximum non-seize load, metal corrosion test and appearance. When there are no changes in raw materials and production processes that may affect product quality, the inspection items in the delivery cycle include: sulfur content, phosphorus content and chlorine content at least once a month. 3) type detection Type testing is carried out in the following cases: a) When a new product is put into production or product type identification; b) When there are major changes in raw materials, production processes, etc., which may affect product quality; c) When there is a big difference between the factory inspection results and the last type inspection results.
5. Batch Under the condition that the raw materials and production process remain unchanged, each can or kettle of the product is a batch. 1) Sampling Sampling is carried out in accordance with GB/T 4756, and the sampling amount should meet the required quantity for ex-factory inspection or type inspection and reserved samples. 2) Judgment rules The factory inspection or type inspection results should be all qualified before leaving the factory. 3) Re-inspection rules If the factory inspection results do not meet the requirements of the quality indicators in Table 1, re-extract double samples from the same batch of products according to the provisions of GB/T4756, and re-inspect the non-conforming items. If the re-inspection results still do not meet the technical requirements , the batch of products is judged to be unqualified. 6. Standards, Packaging, Shipping and Storage Product marking, packaging, transportation, storage and delivery acceptance shall be carried out in accordance with SH/T 0164.
