This standard specifies a method for determining the conductivity of rare earth yellow phosphors for white LED lamps under excitation of 440 nm480 nm blue light. It is suitable for phosphors with a conductivity range of 0 S/cm100 µS/cm. The standard describes sample prepative, Conductivity Meter calibrated and measurement procedures to ensure the accuracy and conformity of the test process. It is suitable for quality control and research of phosphors for LED lamps.
