Test method
4.1 Sensory index
GB 8935—88
4.1.1 Properties and color: Take a clean, transparent and colorless glass test tube with a diameter of 1.5~2cm, inject the melted industrial lard into it, and observe its transparent state and color; then, in the melted state, let it stand for a suitable time and visually observe whether there is any sediment; finally, place it in an environment of 15~20℃ and visually observe the solid state properties and color after it solidifies. : 4.1.2 Odor: Test by sense of smell.
4.2, Physical and chemical indicators
4.2.1 Acid value: Determine according to the determination method of acid value in GB5009.37. 4.2.2 Water content: Determine according to the method specified in GB5009.3. 4.2.3 Content of substances insoluble in ether: Determine according to the method in Appendix A of this standard. 5 Inspection rules
5.1 Inspection
Each batch of products leaving the factory must be inspected and qualified by the enterprise inspection department, and the inspection certificate must be issued before it can leave the factory. 5.2 Sampling method
5.2.1 Sampling ratio: The number of sampled barrels for each batch is 10% of the total number of barrels. If the batch is too large or too small, the sampling ratio can be appropriately increased or decreased according to the size of the batch. However, when the quantity is large, the number of sampled barrels shall not be less than 5%. 5.2.2 Sampling method: Sampling barrels and samples should be randomly selected from the original barrels filled with each batch of products. 5.2.3 If any indicator in the inspection results does not meet the requirements of this level, re-inspection is allowed once. 5.3 Re-inspection: Re-sampling inspection should be carried out at double the ratio of the original batch. If the re-inspection is qualified, it will be considered qualified, otherwise it should be reprocessed or downgraded.
6 Marking, packaging, storage, transportation
6.1 Marking: The outer skin of the container must be marked with the product name, grade, weight (gross weight, net weight), company name, production date, storage conditions and the word "verification".
6.2 Packaging: Use clean iron barrel containers for packaging, and the seal should be tight. 6.3 Storage: The packaged industrial lard should be stored in a well-ventilated warehouse. The product storage shelf life is half a year. 6.4 Transportation: During transportation, it must not be exposed to sunlight or rain. It must not be mixed with toxic substances. 7 Others
7.1 If there are special specifications for export or domestic sales, it can be implemented according to the terms of the contract. 8
A1 Determination of ether-insoluble substances
GB 8935—88
Appendix A
Determination of ether-insoluble substances
(Supplement)
A1.1 Sample preparation: For solidified oil samples, they must be heated in a 50℃ water bath for 30 minutes before testing, and then cooled and mixed to make them uniform. A1.2 Operation method: Weigh 50g of the sample, place it in a conical flask, and add the same amount of ether to fully dissolve the sample. Filter with a No. 1 sand core funnel that has been dried to constant weight. Rinse the sand core funnel with ether several times until the oil stains are washed off, and then dry the funnel in an oven at 100-105℃ to constant weight.
A1.3 Calculation:
Wherein: a—
Content of ether-insoluble substances in the sample, %; mass of funnel, g;
Mass of funnel and insoluble substances, g;
Mass of oil sample, g.
The allowable error of the results of two parallel tests shall not exceed 0.04%, and the average of the two measurements shall be the final result. Additional remarks:
