EN 13032-4:2015 (E)
Introduction
This standard provides requirements to perform reproducible photometric and colorimetric measurements on
LED lamps, LED modules and LED luminaires (LED devices). It also provides advice for the reporting of the
data.
The availability of reliable and accurate photometric data for LED devices is a basic requirement for designing
good lighting systems and evaluating performance of products. By obtaining these data through
measurements in specific normalized measuring conditions the consistency of the data should be ensured
between different laboratories (within the limits of the declared measurement uncertainty) and comparison of
different products on the same basis is possible.
This standard aims in particular to cover measurement methods for testing the compliance of LED devices
with the photometric and colorimetric requirements of LED performance standards (see Clause 2) issued by
IEC/TC 34/CLC/TC 34 “Lamps and related equipment” and/or relevant European regulations.
LED devices offer a large variety of configurations in respect to geometry and/or colour. For each
configuration the photometric and colorimetric performances are considered individually.

1 Scope
This European Standard specifies the requirements for measurement of electrical, photometric, and
colorimetric quantities of LED lamps, LED modules and LED luminaires, for operation with AC or DC supply
voltages, possibly with associated LED control gear. LED light engines are assimilated to LED modules and
handled accordingly. Photometric and colorimetric quantities covered in this standard include total luminous
flux, luminous efficacy, partial luminous flux, luminous intensity distribution, centre-beam intensity, luminance
and luminance distribution, chromaticity coordinates, correlated colour temperature (CCT), colour rendering
index (CRI), and angular colour uniformity.
This European Standard does not cover LED packages and products based on OLEDs (organic LEDs).
