Overview

SIST EN 13032-4:2015+A1:2019 - part of the EN 13032 series - is the European standard that defines how to measure and present photometric, colorimetric, and electrical data for LED lamps, LED modules, light engines and luminaires. It applies to devices operated from AC or DC supplies, including those with associated control gear, and explicitly excludes LED packages and OLED-based products. The standard targets consistent, reproducible reporting of performance metrics used in lighting design, certification and regulatory compliance.

Key topics and technical requirements

The standard covers laboratory, measurement and reporting requirements for LED products, including:

• Scope and terms - definitions for LED product types (DUT), operating positions and test conditions.
• Laboratory and environmental conditions - test room, ambient and surface temperature, air movement and stabilization before measurement.
• Electrical test conditions - test voltages, currents and power-supply specifications for reproducible electrical measurements.
• Measurement instruments & methods - requirements for integrating spheres, goniophotometers, photometers and luminance meters, including spectral responsivity and stray-light screening.
• Photometric quantities - measurement and presentation of total luminous flux, partial (useful) luminous flux, luminous intensity distribution, centre-beam intensity/beam angles, luminance and luminance distribution, and luminous efficacy.
• Colorimetric quantities - chromaticity coordinates, correlated color temperature (CCT), Color Rendering Index (CRI) and spatial/ angular color uniformity.
• Measurement uncertainty - guidance and example uncertainty budgets for luminous flux, intensity, color and electrical parameters.
• Presentation of results - required test-report content, data presentation formats and information on device mounting, age, and operating conditions.
• Guidance annexes - practical laboratory conditions, sensitivity coefficients, rated-value determination and links to ecodesign regulations.

SIST EN 13032-4 is essential for:

• Manufacturers verifying product claims and preparing datasheets for LED lamps, modules and luminaires.
• Accredited test laboratories performing photometric and colorimetric measurements using integrating spheres and goniophotometers.
• Lighting designers and specifiers who rely on accurate luminous flux, intensity distribution, CCT and CRI data.
• Procurement teams and certifiers checking compliance with ecodesign and energy-labeling requirements.
• Regulators and conformity assessment bodies referencing standardized methods for regulatory compliance.

Keywords: SIST EN 13032-4:2015+A1:2019, LED lamps measurement, photometric data, luminous flux, CCT, CRI, goniophotometer, integrating sphere, measurement uncertainty, ecodesign.

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 document does not cover LED packages. Described measurement methods for LED lamp or
luminaires may apply as measurement methods for OLEDs products."
