This International Standard specifies performance requirements for high-pressure sodium
vapour lamps for general lighting purposes which comply with the safety requirements of
IEC 62035.

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 dealing with the lamp starting test and associated information for
ballast/ignitor design are different depending on the practice of the country in which the lamp
type was originally developed.
