This International Standard specifies the dimensions of camera accessory shoes, with and without electrical contacts, for photoflash lamps and electronic photoflash units. The dimensions given in Figures 1 and 2 are basic for the solid shoe. When an accessory shoe is equipped with springs or other devices for holding the accessory foot tightly or maintaining good electrical contact, the dimensions of the shoe can be changed within the range in which their interchangeability and functions will not be affected.
Specified are methods of measurements and 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 camera shutter is fully or nearly fully open.
Specifies the methods for measuring the characteristics peculiar to the control such as accuracy and repeatability. Also lays down the numerical values of the integral of time of the object luminance and of the exposure given to an object by flash equipment with automatic exposure control, and the maximum deviation from these nominal values.
Specifies type and dimensions of the electrical connectors (plug and socket) to be used for electronic photoflash equipment. Gives a limited number of types of connector and the dimensions to be used for the connection between flash unit and flash synchro-cords.
1 This standard applies to the following electronic flash apparatus for photographic purposes, having a stored energy not exceeding 2000 J, together with associated apparatus and not intended to be subjected to dripping or splashing:— apparatus of the single-flash type which can have more than one flash head operating at the same time;— apparatus for the illumination of sequential photographic exposures;— battery chargers and supply units to be used in connection with electronic flash apparatus for photographic purposes. These auxiliary units may form a part of the mains plug;— accessories, such as light regulators and slave units, specified in the instruction leaflet.This standard does not apply to stroboscopes.As long as no appropriate requircmcnts cxist for apparatus having a stored energy exceeding 2000 J, this standard may be used, in so far as it is applicablc.Additional requirements may be neecssary. eg. for explosion and thermal radiation.With regard to the supply, the following categories are covered:— mains-operated apparatus;— battery-operated apparatus;— apparatus having a combination of mains and battery supply.This standard is intended to cover apparatus which can be used both in moderate and tropical climates.For the modelling lamps combined with electronic flash apparatus for photographic purposes, additional requirements may be taken from I EC Publication 598-2-9: Luminaires. Scction Nine Photo and Film Luminaires (Non-professional), as far as applicable.2 This standard does not apply to apparatus designed for a rated supply voltage exceeding 250 V (r.m.s.) against earth.3 This standard is concerned with safety only and not with the other properties of the apparatus (see Clause 3).
ISO 518:2006 specifies the dimensions of camera accessory shoes, with and without electrical contacts, for photoflash lamps and electronic photoflash units. The dimensions given are basic for the solid shoe. When an accessory shoe is equipped with springs or other devices for holding the accessory foot tightly or maintaining good electrical contact, the dimensions of the shoe can be changed within the range in which their interchangeability and functions will not be affected
This part of IEC 61966 is applicable to the assessment of colour reproduction of digital cameras used in open computer systems and similar applications.
The International Standard specifies the electrical requirements of the camera synchronizer, the ignition circuit in the photoflash unit and the cable to connect these, and the test methods to secure positive firing of the photoflash unit.
