BS IEC 60747-5-11:2019

What is BS IEC 60747-5-11 - Radiative and Nonradiative currents of light-emitting diodes (LED) about?   

BS IEC 60747 is a series of the international standard used for semiconductor devices that have their electrical conductivities lying between that of good conductors and insulators  
BS IEC 60747-5-11 is one of the parts of the BS IEC 60747 series of documents that specifies the measuring methods of radiative and nonradiative currents of light-emitting diodes (LED) that result in manufacturing good quality optoelectronic devices.
