一硒化铕的国家标准

目前中国大陆尚未发布一硒化铕的国家标准，但以下为一些相关的国际标准：

1. ASTM C1551-21 "Standard Test Method for Determination of Thermal Conductivity of Advanced Ceramics by Thermal Conductivity Meter Method"

2. ASTM C1398-17 "Standard Test Method for Thermal Conductivity of High-Modulus Fibers by Means of a Transient Line-Source Technique"

3. ISO 12667:2010 "Fine ceramics (advanced ceramics, advanced technical ceramics) - Test method for thermal diffusivity of monolithic ceramics by the laser flash method"

4. ISO 22007-4:2015 "Fine ceramics (advanced ceramics, advanced technical ceramics) - Test method for thermal diffusivity of monolithic ceramics by the comparative longitudinal vibration technique"

这些标准主要是针对一硒化铕的热学性能进行测试和评价的，如热导率、热扩散率等。针对其他方面的标准，需要根据不同的应用领域和具体要求进行制定。
