IEC 60357 pdf download – Tungsten halogen lamps (non-vehicle) – Performance specifications
1General1.1Scope
This International Standard specifies the performance requirements for single-capped anddouble-capped tungsten halogen lamps， having rated voltages of up to 250 V, used for thefollowing applications:
Projection (including cinematograph and still projection)Photographic (including studio)
Floodlighting
Special purposeGeneral purpose. Stage lighting
For some of the requirements given in this standard reference is made to “the relevant datasheet”.For some lamps these data sheets are contained in this standard.For other lamps,falling under the scope of this standard，the relevant data are supplied by the lampmanufacturer or responsible vendor.
The requirements of this standard relate only to type testing.
NOTE The requirements and tolerances permitted by this standard correspond to testing of a type test sample,submitted by the manufacturer for that purpose. In principle this type test sample should consist of units havingcharacteristics typical of the manufacturer’s production and being as close to the production centre point values aspossible.
lt may be expected with the tolerances given in the standard that products manufactured in accordance with thetype test sample will comply with the standard for the majority of production.Due to the production spreadhowever, it is inevitable that there will sometimes be products outside the specified tolerances.For guidance onsampling plans and procedures for inspection by attributes,see IEC 60410.
