GB/T 14634.6-2010 《Test methods of rare earth three-band phosphors for fluorescent lamps - Part 6: Determination of specific surface area》 Related products

"GB/T 14634.6-2010" is the sixth part of the series of standards "Test methods for rare earth trichromatic phosphors for lamps". It specifies specific test methods for measuring the specific surface area of this type of phosphor, usually using the BET method based on the physical adsorption of gases (such as nitrogen). The standard details the principle of measurement, the required Reagent and equipment, sample preparation steps, operating procedures, result calculation and reporting format. It aims to provide a standardized core physical performance test method for the production, application and mass evaluation of phosphors for lamps, ensuring stable and comparable performance.
