1General
1.1scope
This standard specifies the performance requirements for high-pressure mercury vapour lampsfor general lighting purposes, with or without a red correcting fluorescent coating.
For some of the requirements given in this standard, reference is made to “the relevant lampdata sheet”. For some lamps these data sheets are contained in this standard. For otherlamps, 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 samplesubmitted 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 spread however,it is inevitable that there will sometimes be products outside the specified tolerances. For guidance on samplingplans and procedures for inspection by attributes, see lEC 60410.
1.2 Normative references
The following normative documents contain provisions which，through reference in this text,constitute provisions of this International Standard. For dated references,subsequentamendments to or revisions of，these publications do not apply. However，parties toagreements based on this International Standard are encouraged to investigate the possibilityof applying the most recent edition of the normative document indicated below. For undatedreferences, the latest edition of the normative document referred to applies. Members of lECand lSO maintain registers of currently valid International Standards.

1.3 Definitions
For the purposes of this International Standard, the following terms and definitions, as well as others given in IEC 60050(845), apply
1.3.1
high pressure mercury (vapour) lamp
high intensity discharge lamp in which the major portion of the light is produced, directly or indirectly, by radiation from mercury operating at a partial pressure in excess of 1 00 kilo pascals
NOTE This term covers clear, phosphor coated (mercury fluorescent) and blended lamps. In a fluorescent mercury discharge lamp, the light is produced partly by the mercury vapour and partly by a layer of phosphors excited by the ultraviolet radiation of the discharge.
