The factory inspection includes the following items. a) Sensory inspection; b) Inspection of specification size and its deviation and shape error; c) Moisture content and immersion peeling in the physical and mechanical performance test items. 7.3 Type inspection 7.3.1 Type inspection items are all items in the technical requirements. 7.3.2 When normal production has been completed for one year; in one of the following situations, type inspection should be carried out. a) Trial-type appraisal of new products or product transfer to factory production; b) During formal production, such as when there are major changes in structure, raw materials, and processes; c) When the product has been discontinued for more than half a year and production is resumed; d) When there is a big difference between the factory inspection result and the last type inspection result; e) When the national quality supervision agency proposes type inspection requirements. 7.4 Principles of group batching Products with the same raw material variety, production conditions, specifications, and types are an inspection lot. 7.5 Sampling plan 7.5.1 Sensory inspection sampling plan 7.5.1.1 To ensure that the finished product meets the requirements of the standard, the manufacturer determines its grade by inspecting the appearance quality of bamboo cutting boards one by one. 7.5.1.2 When performing sensory inspection on batches of bamboo cutting boards, the normal inspection secondary sampling plan in GB/T 2828.1-2012 shall be adopted, and the inspection level shall be Ⅱ, The Acceptance Quality Limit (AQL) is 4.0, which should meet the requirements of Table 6. 7.5.2 Sampling plan for inspection of specification size, deviation and shape error When inspecting specifications, sizes, deviations, and shape errors, the normal inspection sub-sampling plan in GB/T 2828.1-2012 shall be used. The level is I, and the acceptance quality limit (AQL) is 6.5, which should meet the requirements of Table 7. 7.5.3 Sampling plan for physical and mechanical performance inspection Samples are randomly selected from the submitted inspection batch. The sampling plan is shown in Table 8.Items that fail the first sampling test are allowed to be in the same batch. Double sampling re-inspection of the product, and the re-inspection is divided into two groups. 7.6 Judgment rules Sensory requirements, size and deviation, and shape error items meet the technical requirements of the corresponding category and level, and the batch of products is judged to be suitable If unqualified, double sampling for re-inspection, if still unqualified, the batch of products will be judged as unqualified products. The physical and mechanical performance items are in line with the corresponding According to the technical requirements, the batch of products is judged to be qualified. If it is unqualified, samples will be doubled for re-inspection. If it is still unqualified, the batch of products will be judged as unqualified products. 8 Identification, packaging, storage and transportation 8.1 Identification 8.1.1 Logo The packaging, storage and transportation graphics shall be implemented in accordance with GB/T 191. 8.1.2 Label The package should be marked with the name of the factory, address, product name, specification, quantity, grade, date of manufacture, implementation standard number, main material composition, Use the surface and other signs, and place the instruction manual, inspection certificate, and other product signs can be stamped according to the supply and demand contract. 8.2 Packaging 8.2.1 The packaging should meet the requirements of firmness, cleanliness, moisture-proof and beautiful appearance. 8.2.2 The packaging materials should be dry, clean, free of peculiar smell, and should not affect product quality. 8.3 Storage and transportation In storage and transportation, it should be protected from moisture, fire, damage to packaging, pollution, and isolation from toxic, harmful and odorous items. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 38742-2020_English be delivered?Answer: Upon your order, we will start to translate GB/T 38742-2020_English as soon as possible, and keep you informed of the progress.
