0. FOREWORD
0.1 This Indian Standard was adopted by the Indian Standards Institution
on 23 September 1981, after the draft finalized by the Electric Lamps and
Accessories Sectional Committee had been approved by the Electrotechnical
Division Council.
0.2 This standard ( Part II ) has been prepared to cover electrical characteristics for lamps starting and operation of high pressure sodium vapour
lamps. Additional information for purposes of design of ballast, luminaires
It is hoped that
and ignitors, where essential, have also been incorporated.
at a later stage ‘it shall be possible to prepare a more detailed standard
which will state requirements
necessary for safety together with test
conditions and procedures for complete testing of these lamps.
0.3 This standard~consists of the following two parts:
Part
I General requirements and tests; and
Part II Standard lamp data sheets.
0.3.1 This standard shall be read in conjunction
standard.
with Part I of this
0.4 In the preparation of this standard ( Part II ) assistance has been derived
from IEC Pub-662 ( 1980 ) High pressure sodium vapour lamps, issued by
the International Electrotechnical Commission.
0.5 The life expectancy and nominal lumen output of high pressure sodium
vapour lamps are under consideration by the committee and would be added
at a later date as and when sufficient data are available, However, for the
purpose of guidance, the nominal life of such lamps may be taken as 5 000
-hours.
0.6 For the purpose of deciding whether a particularrequirement
of this
standard is complied with, the final value, observed or calculated, expressing
3
IS : 9974 ( Part II ) - 1981 ,
the result of a test. shall be rounded off in accordance with IS : 2-1960*.
The number of significant places retained in the rounded off value should be
the same as that of the specified value in this standard.
1. SCOPE
1.1 This standard ( Part II ) comprises lamp data sheets for high pressure
sodium vapour lamps covered -by this standard.
2. TERMINOLOGY
2.1 For
the purpose of this standard,
(Part I )-19817 shall apply.
3. &ECOMMENDED
LAhlP
the definitions given in IS : 9974
TYPES
3.1 The recommended types of high pressure sodium vapour lamps covered
by this standard are as follows:
a)
150 W Tubular clear,
b)
150 W Elliptical.-
diffuse coating,
c) 250 W Tubular clear,
d) 250 W Elliptical - diffuse coating,
e) 400 W Tubular clear, and
f) 400 W Elliptical -
diffuse coating.
4. LAMP DIMENSIONS CAP AND OTHER DETAILS
4.1 The overall lamp dimensions, bulb diameter and type of caps that are to
be employed in the lamp shall be asgiven in the relevant data sheet. Schematic ‘drawings for location of lamp dimensions specified in the data sheets
have been indicated in Fig. 1 and 2.

Norx - There are two designs of lamp presently in use which are compatible in operation, but which require different starting conditions.
Some lamp designs require a minimum pulse height of 1 600 V whereas other
designs require a minimum pulse height of 1 800 V. Illformation is to be provided by the lamp manufacturer
as to,which ignitor pulse height and width
are appropriate.
For future starting compatibility of both lamp types, it is recommended
ignitors are designed with a minimum pulse height of 1.800 V.
