IEC 60809-2021 pdf free download – Lamps and light sources for road vehicles – Dimensional, electrical and luminous requirements.
This document is applicable to electric light sources (see Note 1) for use in automotiveapplications，for example in road illumination devices and/or light signalling devices for roadvehicles.
lt is especially applicable to light sources listed in UN Resolution R.E.5 and light sources subjectto other legislations.
This document specifies the technicalrequirements for interchangeability for exampledimensional, electrical and photometrical characteristics,and includes test methods.
For the light sources listed in this document, the data sheets are contained either in thisdocument or are included by reference to UN Resolution R.E.5.
Performance requirements are specified in IEC 60810，for example life,torsion strength,resistance to vibration and shock.
The requirements for miniature light sources for supplementary purposes，not subject tolegislation, are specified in lEC 60983.
NOTE 1 The terms “lamp”and “light source”are both used in this document to mean the same product, so the twoterms are interchangeablethroughout this document.
NOTE 2 ln various vocabularies and standards, differentterms are used for”incandescent lamp”(IEC 6O050-845:1987,—845-07-04),”discharge lamp”(IEC 60050-845:1987,845-07-17) and “LED lamp”. In thisdocument “iflament lamp”, “discharge lamp”and “LED light source”are used， however， where only “lamp”or “lightsource” is written, all light sources,，independent of the technology used,are meant,unless the context clearly showsthat it applies to one kind of technology only. In the UN Regulations，the word “light source”is used for the productsspecified in this document.
NOTE 3 wherever the term “device”is used,it is meant to designate equipment which is used as a luminaire. Itcan for instance take the form and purpose of a headlight or signal light.

3.1
ageing period
preconditioning period of the light source before initial values are taken
[SOURCE: IEC 60050-845:2020,845-27-108, modified – “period” has been added to the termand the note to entry has been deleted.]
3.2
category
basic design of standardized light sources
Note 1 to entry: Each specific designation,for example P21/5W，H4,D2R forms a category. Most of thesedesignations are taken from the R.E.5.
3.3
conformity of production
compliance of the series production of a given type with the requirements of the relevantspecification
Note 1 to entry: Local regulations may require checking the conformity of production by a government agency.
3.4
dipped beampassing beamlow beam
headlight designed to illuminate the road ahead of the vehicle without causing undue glare topeople in front of the vehicle carrying it, particularly to the drivers of approaching vehicles
Note 1 to entry: The term used in the UN regulation No. 48 is “passing-beam”.
3.5
initial luminous flux
luminous flux measured at the end of the ageing period.IEC 60809 pdf download.
