ISO 20351:2017
Hind 54,15 EUR
Fine ceramics (advanced ceramics, advanced technical ceramics) -- Absolute measurement of internal quantum efficiency of phosphors for white light emitting diodes using an integrating sphere
ISO 20351:2017 specifies a method of absolute measurement (using an integrating sphere) of internal quantum efficiency of phosphor powders which are excited by UV or blue light and emit visible light, and which are used for white light-emitting diodes (LEDs). ISO 20351:2017 can be adopted for the measurement of phosphors used in non-white LEDs, for example, green, orange, pink or purple LEDs.

ISO 20407:2017
Hind 54,15 EUR
Fine ceramics (advanced ceramics, advanced technical ceramics) -- Test method for interfacial tensile and shear fatigue properties of ceramic joining loaded in constant amplitude at room temperature
ISO 20407:2017 specifies a test method for determining interfacial tensile/tensile or shear/shear cyclic fatigue properties of ceramic-ceramic, ceramic-metal, and ceramic-glass joining loaded in the constant amplitude at room temperature. Procedures for test piece preparation, test modes and rates (load rate or displacement), data collection and reporting procedures are given. ISO 20407:2017 applies primarily to ceramic materials, including monolithic fine ceramics and whisker-, fibre- or particle-reinforced ceramic composites. This test method can be used for material research, quality control, and characterization and design data-generation purposes.
