IEC 60188:2001 pdf download.High-pressure mercury vapour lamps -Performance specifications.
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 100 kilopascals

(1EV 845-07-201
1.3.2
nominal value
approximate quantity value used to designate or Identify a lamp
1.3.3
rated value
quantity value for a characteristic of a lamp for specified operating conditions. The value and the conditions are specified in this standard, or assigned by the manufacturer or responsible vendor
1.3.4
lamp starting voltage
r.m,s. voltage at lamp terminals at which the lamp starts
1.3.5
minimum open circuit voltage for stable operation
minimum open circuit voltage to be provided by an Inductive ballast for stable operation of the lamp
1.3.6
initial readings
starting and warm-up characteristics of a lamp, measured before ageing, and the electrical and photometric characteristics of a lamp, measured at the end 01 the ageing period
1.3.7
red ratio
ratio of the luminous flux emitted by the lamp in the red portion of the visible spectrum to the total luminous flux of the lamp. For the purposes of this standard, the red portion is defined by the part of the visible spectrum comprising the wavelengths above 600 nm
1.3.8
reference ballast
special Inductive type ballast, designed for the purpose of providing comparison standards for use in testing ballasts, for the selection of reference lamps and for testing regular production lamps under standardised conditions. It Is essentially characterized by the fact that at its rated frequency. it has a stable voltage/current ratio which is relatively uninfluenced by variations in current, temperature and magnetic surroundings, as outlined in the relevant ballast standard
1.3.9
calibration current of a referenc. ballast
value of the current on which the calibration and control of the reference ballast are based
1.3.10
type test
test or a series of tests made on a type test sample for the purpose of checking compliance of the design of a given product with the requirements of the relevant standard
1.3.11
type test sample
sample consisting of one or more similar units submitted by the manufacturer or the responsible vendor for the purpose or a type lest
1.4 Lamp requirements
1.4.1 General
A lamp, on which compliance with this standard is claimed, shall comply with the requirements of IEC 62035.
A lamp shall be so designed that its performance is reliable in normal and accepted use. In general, this can be achieved by satisfying the requirements of the following subclauses.
The requirements given apply to 95 % of production.
For the purposes of this standard, the following designations are used as a Clas5ificatlon according to the rated voltage at lamp terminals:
• Lamp voltage range 70 V — 180 V Designation: HV
• Lamp voltage range >180 V Designation. EHV
The dimensions of a lamp shall comply with the values specified on the relevant lamp data
sheet.
1.4.3 Caps
The cap on a finished lamp shall comply with IEC 60061.1.
1.4.4 StartIng and warm-up characteristics
A lamp shall start within the starting time specified on the relevant lamp data sheet and remain alight for at least I mm.
A lamp shall achieve the warm-up voltage at lamp terminals within the warm-up time specified on the relevant lamp data sheet
The tests shall be made before ageing. using the measuring method given in annex A.
NOTE Normaly 1 should be espected that at 100 % of the rated supply voltage, lamps will start satistacLorIly at temperatures.
