Roadway and outdoor area lighting fixtures are designed to operate in environmental conditions that may expose them to continuous mechanical stress over time.
Wind, road traffic and the characteristics of supporting structures can generate vibrations that affect not only the luminaire itself, but also its components and mounting systems.
For manufacturers, verifying vibration resistance is an important step in product qualification, particularly when luminaires are intended for infrastructure projects and international markets with specific technical requirements.
In this context, ANSI C136.31:2023 serves as a reference standard for assessing the vibration resistance of roadway and area lighting equipment.
A Reference Standard for the North American Market
ANSI C136.31:2023 defines the minimum vibration resistance requirements and associated test methods for luminaires falling within its scope.
The 2023 edition updates the previous 2018 version and represents an important technical reference for manufacturers developing lighting products for the North American market.
For companies that already have test reports or qualification programs based on the previous edition, the update provides an opportunity to review the consistency between applicable requirements, product configuration and the adopted test plan.
A preliminary technical assessment helps identify potential updates, avoiding the automatic transfer of procedures and documentation developed under the previous edition.
From Design to Qualification: The Importance of an Integrated Approach
Vibration resistance depends not only on the structural characteristics of the luminaire. Installation configuration and mounting methods also play a significant role in defining test conditions.
For this reason, an effective qualification program requires a thorough technical assessment of the product before testing begins.
Analytical Group supports lighting manufacturers in managing verification activities in accordance with ANSI C136.31:2023, providing technical expertise and ISO/IEC 17025 accredited testing services performed in Europe.
Our integrated approach also allows vibration testing and electrical safety assessments to be coordinated within a single testing program, aligned with product characteristics and the requirements of international projects.
