IEC 61947-2:2001 specifies requirements for measuring and documenting key performance parameters for CRT and laser-based projectors and other variable resolution projectors that are capable of multiple variable resolutions and in which the image is raster-scanned. This bilingual version (2013-02) corresponds to the monolingual English version, published in 2001-09.
