Photography. Electronic flash equipment. Determination of light output and performance algolia-search-ignore b) offset from pipe centre1 Scope and field of application This International Standard specifies methods of measurement and sets standards of performance for light output, angle of coverage, ready indication, recycle time and number of flashes for electronic flash equipment of the single flash type, which is primarily intended to provide illumination for photography with cameras in which the contacts that control the flash are closed when the shutter of the camera is fully or
