IEC 61947-1 Ed. 1.0 en: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 electro-luminescent panels). Also applies to LCD panels or other fixed resolution imaging devices themselves that are used with overhead projectors.
