Metal halide lamps – Performance specification
|Publication Date:||1 January 2015|
|ICS Code (Fluorescent lamps. Discharge lamps):||29.140.30|
This International Standard specifies the performance requirements for metal halide lamps for general lighting purposes.
For some of the requirements given in this standard, reference is made to "the relevant lamp data sheet". 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 lamp manufacturer or responsible vendor.
The requirements of this standard relate only to type testing.
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 having characteristics typical of the manufacturer's production and being as close to the production centre point values as possible.
It may be expected that with the tolerances given in the standard, the product manufactured in accordance with the type test sample will comply with the standard for the majority of production. Due to the production spread however, it is inevitable that there will sometimes be products outside the specified tolerances. For guidance on sampling plans and procedures for inspection by attributes, see IEC 60410.
