What is BS EN 13032‑4 about?
BS EN 13032‑4 is the fourth part of an international multi-series standard that covers lighting systems such as LED lamps, modules, and luminaires.
BS EN 13032‑4 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 BS EN 13032‑4 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.
Note 1: BS EN 13032‑4 does not cover LED packages. Described measurement methods for LED lamps or luminaires may apply as measurement methods for OLEDs products.
Who is BS EN 13032‑4 for?
BS EN 13032‑4 on photometric data of lamps is useful for:
- Manufacturers and suppliers of LED lamps, modules, and luminaires
- Dealers and distributors of LED lamps, modules, and luminaires
- Designers of LED lamps, modules, and luminaires
- Test houses for LED lamps, modules, and luminaires
Why should you use BS EN 13032‑4?
The availability of reliable and accurate photometric data for LED devices is a basic requirement for designing good lighting systems and evaluating the performance of products. LED devices offer a large variety of configurations with respect to geometry and/or colour. For each configuration, the photometric and colorimetric performances are considered individually.
BS EN 13032‑4 provides you with the 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.
BS EN 13032‑4 helps its users by obtaining data through measurements in specific normalized measuring conditions, which gives the consistency of the data that should be ensured between different laboratories, and comparison of different products on the same basis is possible.
BS EN 13032‑4 aids in particular to cover measurement methods for testing the compliance of LED devices with the photometric and colorimetric requirements of LED performance standards issued by IEC/TC 34/CLC/TC 34 “Lamps and related equipment” and/or relevant European regulations.
What’s changed since the last update?
BS EN 13032‑4:2015+A1:2019 supersedes BS EN 13032‑4:2015, which is withdrawn. BS EN 13032‑4:2015+A1:2019 includes amendment 1 approved by CEN on 21 March 2019.
