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.
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 having
characteristics typical of the manufacturer’s production and being as close to the production centre point values as
possible.
It may be expected with the tolerances given in the standard that 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.
