This standard specifies the code, definition and general requirements for solvent-free polymerizable resin compounds for electrical insulation (hereinafter referred to as compounds). This standard applies to resin or elastomer compounds composed of one or more chemically active ingredients. Common compounds of this type include casting resins, impregnating resins, potting glues, embedding glues, encapsulating glues, glues and coating powders. They can be cured into products by heating or not under the application of pressure, and no inert volatiles escape during curing.

5 General requirements
5.1 Each batch of composites shall meet the requirements specified in the corresponding product standards. 5.2 Inspection rules
5.2.1 Composites produced by the same raw materials, processes and equipment systems after one mixing are defined as one batch, and each batch shall be inspected. The items of factory test are specified in the product standard. 5.2.2 The type inspection items are all the items of technical requirements in the product standard, and shall be conducted at least once every three months. Type tests shall also be conducted when the raw materials, processes and equipment systems are changed. 5.2.3 The sample should be drawn from no less than 5% of the total number of packages in a batch of products. If the batch size is small, it should not be less than 3. Stir the materials in the package thoroughly, take appropriate amount of each, mix carefully and evenly, and use it as the sample. The sample should be kept at room temperature for at least 4 hours before testing.
5.2.4 If any of the test results does not meet the requirements of the technical requirements, double sampling should be taken from the packages in the batch that have not been sampled according to Article 5.2.3. Repeat the test. If one result still does not meet the requirements, this batch of products is unqualified. 5.3 Packaging and marking
5.3.1 The compound (including group packaging) should be packed in a clean, dry iron drum or other suitable container, and strictly sealed. The preferred volume of the container is 2, 5, 6.3, 20, 30, 200L.
5.3.2 The packaging barrel should be marked with the manufacturer's name, product model and name, manufacturing date (or batch number), gross weight, net weight and "handle with care" or a pictorial mark. If it is a dangerous product, it also needs to be marked with its words or pictorial mark. The relevant regulations are in accordance with GB190 and GB191. 5.3.3 Each batch of products should be accompanied by a product inspection certificate. If the user unit requires it, the manufacturer should provide a type test report. 5.4 Storage and transportation
5.4.1 The product should be stored in a clean, dry, well-ventilated warehouse with a temperature of 20-30℃ and not exposed to direct sunlight. 5.4.2 If the product is stored in the sealed container of the original packaging and exceeds the storage time specified in the product standard, it should be inspected before use. If the inspection result still meets the requirements of the product standard, it can still be used. 5.4.3 During transportation, the product should be protected from direct sunlight and rain, and should not be close to heat and fire sources.
