This standard BS EN 61947-1:2002 Electronic projection. Measurement and documentation of key performance criteria is classified in these ICS categories:
37.020 Optical equipment
33.160.60 Multimedia systems and teleconferencing equipment
35.180 IT terminal and other peripheral equipment
37.040.10 Photographic equipment. Projectors
33.160.99 Other audio, video and audiovisual equipment
31.120 Electronic display devices
IEC 61947-1:2002 specifies requirements for measuring and documenting key performance parameters for electronic projection systems with fixed resolution projectors in which the light source and projection/magnification optics are an integral part of the system (i.e. individual pixel light sources or matrix displays such as liquid crystal, DMD, plasma, or electroluminescent panels). It also applies to LCD panels or other fixed resolution imaging devices themselves that are used with overhead projectors. This bilingual version (2013-02) corresponds to the monolingual English version, published in 2002-08.
