- Scope
- 1. This standard is only applicable to the determination of the chemical composition of ZQAl14-8-3-2 and ZQAl12-8-3-2 materials. When there is a dispute about the chemical composition of the product. The analysis methods specified in this standard shall prevail. 2. The number of parallel analyzes of the same sample shall not be less than three. The difference between the analysis results shall be within the allowable error and the arithmetic square value shall be taken as the final analysis result. 3. For the different analysis methods listed for the same element in this standard, when conducting arbitration analysis, the arbitration unit and the requesting arbitration unit may decide to use a certain method through negotiation. 4. The reagents used are all analytical grade reagents (Level 2) unless otherwise specified. 5. The water used for reagent preparation and analysis is ion-exchange water or water of equivalent purity. 6． The solutions mentioned in the standard are all aqueous solutions except for the specified solvents. 7． The concentration ratio of the solution mentioned in the standard, for example, 1:2 refers to 1 part of hydrochloric acid (specific gravity 1.19), sulfuric acid (specific gravity 1.84), nitric acid (specific gravity 1.40) or ammonia (specific gravity 0.90) mixed with 2 parts of water (volume ratio) . 8. The percentage concentration of the solution referred to in the standard refers to the number of grams of solute contained in 100ml of solution. For example, 10% sodium thiosulfate solution refers to 10g of sodium thiosulfate dissolved in water and then diluted with water to 100ml. 9. The instruments and measuring tools used in this standard must be certified and qualified. 10. Hot water referred to in the standard refers to water with a temperature of 70 to 80°C, and warm water refers to water with a temperature of 40 to 50°C. Room temperature refers to the ambient temperature of 20 to 25°C.
