Core Value of the Standard - The standard "Method for determination and representation of silicon dioxide in high purity quartz" aims to establish a unified method for measuring and reporting SiO₂ content, addressing issues of measurement inconsistency and incompleteness [2][3][4] Group 1: Standard Scope - The standard covers high purity quartz products with SiO₂ content of at least 99.9%, allowing other quartz products with similar purity to refer to it, ensuring broad applicability and flexibility [1][13] Group 2: Main Technical Content - A scientific and unified system for measuring and representing SiO₂ content is established, which includes: 1. Measurement of SiO₂ content using ICP-OES method for precise derivation [2] 2. Standardized expression rules for SiO₂ content to avoid discrepancies in interpretation, ensuring consistency and comparability across different enterprises and testing institutions [3] 3. Specification of core information required in test reports to enhance credibility and traceability of results, providing a complete basis for production, trading, and quality assessment [4] Group 3: Significance of Implementation - The implementation of this standard will empower the high purity quartz industry in multiple dimensions: 1. Filling the industry gap by resolving the lack of a unified standard for SiO₂ content detection, ending the "detection chaos" and eliminating trade barriers [5] 2. Supporting technological upgrades by providing standard technical support for in-depth research and production technology improvements, guiding enterprises to optimize production processes and enhance product quality [6] 3. Promoting industry collaboration by facilitating efficient communication and cooperation among upstream and downstream enterprises, avoiding mismatches in supply and demand due to non-unified standards [6] 4. Serving national strategies by aligning with the "3.5G new generation information technology industry chain (chips)" framework, aiding breakthroughs in strategic emerging industries like semiconductors and photovoltaics, and laying the foundation for high purity quartz export strategies [6] 5. Moving towards internationalization by establishing a unified standard as a "passport" for high purity quartz products to participate in international competition, enhancing global market influence [6]
