INTRODUCTION TO THE AMENDMENT
This proposal serves:

a) the implementation of the low frequency square wave operation in ILCOS (International

Lamp Coding System):

ILCOS L – wattage – lamp voltage range/starting device/current wave form and frequency –

lamp cap – dimensions

b) the implementation of lamps for use in high-pressure mercury equipment under 5.7.1.2. In

order to distinguish this, other lamps are listed as normal lamps under 5.7.1.1.

c) further editorial changes as being presented with PRESCO(RTK)198 and agreed by

PRESCO.
