The standard increase temperature is greater than the old measurement range, 3.2 also divided into systems. Stir the sample in the test tube regularly, let it start to solidify, and keep it in the tea chamber for about 1 degree. Then, raise the temperature to 1 degree and keep it unchanged for about 1 minute. The temperature at this time is the second freezing point of the sample. The temperature should not be increased by 1 degree. Keep it unchanged for about 1 minute. The temperature at this time is the second freezing point of the sample. The method for measuring the temperature of the sample is not applicable to the company. See Appendix 5.4 [Determination of specific temperature, 25℃

6 Inspection regulations
6.11 The finished products of synthetic thin films shall be inspected by the inspection department of the manufacturer. The manufacturer shall ensure that all products meet the requirements of the standard: Each batch of products shall be accompanied by a quality certificate, including: manufacturer name, product name and trademark, production date (mandatory), product quality certificate and standard number. 6.2 The inspection unit shall inspect the quality of each batch of products according to the quality standards to see whether it meets the requirements of the standard. Each batch shall be inspected once, and different batches shall be inspected separately. 6.3 For each batch of packaging, one unit shall be selected if the number is less than 1, and two units shall be selected if the number is less than 10. After packaging, if the product is solid, it should be inspected again after the degassing film is removed. The product should be cleaned of impurities and then the sample should be evenly distributed. Each sample should be collected by suction tube for 5 to 1m, injected into the sample mixer, and divided into two clean glass bottles with sandpaper holders. The bottles should be marked with the date: manufacturer name, product name, batch number, production date, number and sample collection date: one bottle is for inspection and the other bottle is reserved.
6.4 If one of the indicators in the acceptance results does not meet the requirements of this standard, the manufacturer may conduct a double sampling re-inspection. If the overall results still have indicators that do not meet the requirements, the batch of products cannot be accepted. 6.5 When the supplier has objections to the product quality, the two parties shall resolve it through negotiation or invite a statutory testing organization to request it, and the supplier shall be responsible for the result.
