七硫化二铼的国家标准
目前没有关于七硫化二铼的中国国家标准。在国际上,七硫化二铼的相关标准有:
1. ASTM标准:ASTM标准中有关于七硫化二铼的测试方法和规范,如ASTM C1767-13 "Standard Specification for Stainless Steel Jacketing for Insulation",ASTM E408-13 "Standard Test Methods for Total Normal Emittance of Surfaces Using Inspection-Meter Techniques"等。
2. ISO标准:ISO标准中也有关于七硫化二铼的测试方法和规范,如ISO 7786-1:1999 "Refractory products — Determination of pyrometric cone equivalent (PCE)",ISO 21068-2:2008 "Chemical analysis of silicon-carbide-containing raw materials and refractory products — Part 2: Determination of loss on ignition, total carbon, free carbon and silicon carbide, total and free silica and total and free silicon"等。
以上标准主要是针对七硫化二铼用于相关应用领域的测试方法和规范,以保证产品的质量和性能。
