This standard is the revision of YS/T 517-2006 "sodium fluoride", compared with YS/T 517-2006, the main changes are as follows. - the original standard "This standard applies to hydrofluoric acid or silicic acid and carbonate role made of sodium fluoride" modified to "this standard Suitable for hydrofluoric acid or silicic acid and sodium salt produced by the role of sodium fluoride. - the sample used in the chemical analysis method is a dry sample, so the original table note 2 "table chemical composition calculated by dry basis" Removed. --- As the YS/T 535-2009 "sodium fluoride chemical analysis method" for the determination of fluorine content, increase the conversion of F to NaF items. --- Change the Na2CO3 specified in the original standard to carbonate (CO32-). Rhithers. Rhithers. Rhithers. Rhithers. Rhithers. Rhithers. Rhithers. Rhithertigmaates calling Results The acid salt content is converted to the corresponding "0.37, 0.74, 1.49". --- the original standard "demand side to respond to the products received in accordance with the provisions of this standard re-inspection," modified to "demand side to receive the production Shall be re-tested in accordance with the provisions of this standard. --- increase the order or the contents of the contract. This standard by the National Nonferrous Metals Standardization Technical Committee proposed and centralized. This standard is drafted by Fushun Aluminum Co., Ltd. and China Nonferrous Metals Industry Standard Measurement Quality Institute. This standard is drafted by Fushun Aluminum Company Limited.

Chemical analysis of sodium fluoride in YS/T 535 (all parts)3 request3.1 Sodium fluoride product grade Sodium fluoride is divided into three grades according to chemical composition. Table 1% grade chemical composition NaF SiO2 Carbonate (CO32-) Sulfate (SO42-) acidity (HF) Not in water Solvents H2O Not less than no more than Primary 98 0.5 0.37 0.3 0.1 0.7 0.5 Secondary 95 1.0 0.74 0.5 0.1 3 1.0 Level 3 84 - 1.49 2.0 0.1 10 1.5 Note. The conversion factor for converting the measured amount of fluorine into sodium fluoride is. NaF = (22.99 + 19.00) /19.00 (F) = 2.21 (F). 3.2 appearance quality Sodium fluoride is a white powder. Visual no inclusions.4 test method4.1 Chemical composition Arbitration analysis method according to YS/T 535. 4.2 The appearance of the product quality inspection with visual inspection.5 inspection rules5.1 Inspection and acceptance 5.1.1 The product can be inspected by the supplier's quality inspection department to ensure that the product quality meets the requirements of this standard (or order contract) and fill in Quality certificate. 5.1.2 The purchaser may carry out the re-inspection of the product received in accordance with the provisions of this standard, such as the result of the re-inspection and the grade or order of the certificate Incompatible, should be written in the form of supply to the supplier, by the supply and demand sides to resolve. For the objection should be received within three months from the date of receipt of the product Out. For arbitration, both supply and demand should be sampled in accordance with the provisions of 5.4.2 for arbitration analysis, according to the results of the arbitration analysis to re-determine grade. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of YS/T 517-2024_English be delivered?Answer: Upon your order, we will start to translate YS/T 517-2024_English as soon as possible, and keep you informed of the progress.
