FOREWORD

1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising

all national electrotechnical committees (IEC National Committees). The object of IEC is to promote

international co-operation on all questions concerning standardization in the electrical and electronic fields. To

this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,

Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC

Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested

in the subject dealt with may participate in this preparatory work. International, governmental and non-

governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely

with the International Organization for Standardization (ISO) in accordance with conditions determined by

agreement between the two organizations.

2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international

consensus of opinion on the relevant subjects since each technical committee has representation from all

interested IEC National Committees.

3) IEC Publications have the form of recommendations for international use and are accepted by IEC National

Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC

Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any

misinterpretation by any end user.

4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications

transparently to the maximum extent possible in their national and regional publications. Any divergence

between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in

the latter.

5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity

assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any

services carried out by independent certification bodies.

6) All users should ensure that they have the latest edition of this publication.

7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and

members of its technical committees and IEC National Committees for any personal injury, property damage or

other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and

expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC

Publications.

8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is

indispensable for the correct application of this publication.

9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of

patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

International Standard IEC 60662 has been prepared by subcommittee 34A: Lamps, of IEC

technical committee 34: Lamps and related equipment.

This second edition cancels and replaces the first edition published in 1980 and its

amendments. It constitues a technical revision.

HIGH-PRESSURE SODIUM VAPOUR LAMPS –
PERFORMANCE SPECIFICATIONS
1 Scope

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.

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.

5 Marking

In addition to lamp marking requirements prescribed in IEC 62035, the following symbols,

indicating the starting method shall be marked on the lamp:

– for lamps without an internal starting device and requiring an external ignitor

– for lamps having an internal starting device

NOTE In the U.S.A., lamps are marked with an electrical code that is used to identify the proper ballast. See local

standards. The symbols are not required or used in U.S.A.
6 Dimensions

The dimensions of a lamp shall comply with the values specified on the relevant lamp data

sheet.
7 Caps
The cap on a finished lamp shall comply with IEC 60061-1.
8 Test requirements for lamp starting, warm-up, electrical and photometric
characteristics
8.1 General

For the tests for lamp starting, lamp warm-up and lamp electrical characteristics the lamps

shall be operated in a horizontal position in free air and at an ambient temperature of 25 °C ±

5 °C, on a 50 Hz or 60 Hz sinusoidal power supply using the specified reference ballast at

voltage specified on the lamp data sheet. Lamps shall not be operated during 5 h immediately

prior to making the starting test.
8.2 Lamp starting test
8.2.1 Lamps with external ignitor

In view of various types of ignitors in the market using essentially different methods for

ignition, a well-defined reference device allows to determine whether a lamp is ignitable in

the sense of the standard or not. Since the device also is the basis for comparable

measurements, essential component changes are not permitted unless the responsible IEC

maintenance team has agreed the changes.

All variable starting parameters are given on the lamp data sheet and refer to either

adjustments of the device or to an implicit property thereof (e.g. waveshape), see Figure A.1

for pulse features. If the lamp data sheet requires a second pulse, during the negative half

reference device are given in Annex F.

The pulse characteristics specified on the relevant lamp data sheet are measured at the

device output terminals in open circuit condition.

NOTE In U.S.A., the reference device is not used. A description of the pulse is given in Figure A.3. The starting

pulse is measured with a simulated lamp-load of 20 pF across the lampholder terminals.

The circuit connections for lamp starting shall be such that the pulse is applied to the lamp

through the eyelet terminal of the cap and with the shell substantially at earth potential.

8.2.2 Lamps with internal starting device

The test voltage shall be as indicated in the relevant lamp data sheet. The starting time

measured from applying the test voltage shall not exceed the maximum value shown on the

lamp data sheets.
8.3 Lamp warm-up test

Prior to the warm-up test, the lamps shall have been aged for a minimum of 10 h using a

suitable production ballast and cooled for a minimum of 1 h prior to the test.

The voltage at lamp terminals shall reach a minimum value within the time specified on the

relevant lamp data sheet.
8.4 Ageing

Before the initial readings are taken the lamp shall be subjected to ageing for 100 h. This

operation may be carried out on a production ballast.
8.5 Lamp electrical characteristics

The lamp electrical characteristics shall comply with the values given in the relevant lamp

data sheet, using the measuring method given in Annex G. During measurement of the

electrical characteristics, the external ignitor shall be disconnected from the lamp circuit.

8.6 Extinguishing voltage test

This test shall only be carried out on lamps where an extinguishing voltage is shown on the

lamp data sheet.

The lamp shall be operated on a reference ballast at rated supply voltage and at the

extinguishing voltage shown on the lamp data sheet, achieved, if necessary, by artificial

means. This lamp shall not extinguish when the supply voltage falls from 100 % to 90 % of the

rated value in less than 0,5 s and remains at that value for at least 5 s.
