Upper Material
Technical Conditions for Low-temperature Metal Flexure
Q/T 2224-96
When footwear is worn under low-temperature conditions: there is no generation of grade (fission fusion type). The shoemaking industry can select materials with low resistance to painting for the manufacture of tourism, ancient land and cotton models, etc.: for this reason, he set the shoemaking materials with low sintering resistance as the selection index and the shoemaking materials for the supply of technical repair

Test method
QB/T·2224-96
5.1 The low-humidity agglomeration performance of the upper material shall be tested according to Appendix A of Q1471-1992. The test temperature is ~10±2℃, 5.2 The number of samples shall be not less than four pieces per sample (two pieces in each direction), the test row is 70m long and 65m wide, 3. The test scale is not allowed to have defects such as estimation marks, quality, dirt and scratches. 5.4 The original thickness of the sample shall be in accordance with the original thickness, but the thickness shall not exceed 2.5. B Inspection Rules
Core, 1 The upper materials of the same material, process, specification, year and month are regarded as a batch 6.2 Randomly select a sample from each batch of materials for testing: 8.8 The number of samples of a sample is not the same as the number of samples of superior products, first-class products or qualified products. If the number of samples is not the same, the batch of products is judged as superior products, first-class products or qualified products. If one or more samples do not meet the requirements of qualified products, the batch of products is judged as unqualified.
8.1 If the test results of different samples in the same frequency are different, the lower grade judgment is adopted. 6.5 If the total test does not meet the standard, the test shall be repeated with double the test results and the test results shall be confirmed. Marking
Each batch of products shall be marked with the following contents on the package. 7.1 Manufacturer name, address and city mark.
7.2 Product name (including main raw materials).
Daily production grade and number of this standard.
7.4 Inspection date.
7.5 Factory date.
7.6 Transportation requirements, etc.
