Safety of laser products - Part 19: Moving platform laser products
IEC TS 60825-19:2024 specifies the velocity-dependent closest points of human access (VCPHA) for the classification of moving platform laser products when considering the movement of the platform with respect to a stationary frame of reference. This presupposes that the inherent kinetic hazard of the moving platform creates a zone in which persons would not be reasonably expected to be located. Additionally, it takes neighbouring moving platforms into account by defining stationary and moving apertures. This document is applicable to all laser products whose laser apertures are on a moving platform.
Laser products are sometimes used on moving platforms. Currently the standard IEC 60825-1:2014 considers only a stationary aperture; it does not address the situations where the emitting aperture is mounted on a platform, such as a vehicle, that can be in motion. Failure to consider the effects of the motion of the platform can result in overly restrictive assessment of the hazard.
Although accounting for a platform’s movement during the assessment of a laser product’s classification can lead to less restrictive measurement conditions, it is important not to overlook that there can be apertures, even on other moving platforms, moving at a relative speed of zero or close to zero with respect to the moving platform laser product being classified.

Overview
IEC TS 60825-19:2024 - “Safety of laser products - Part 19: Moving platform laser products” provides guidance for classifying laser products whose laser apertures are mounted on moving platforms. The specification introduces a velocity-dependent closest point of human access (VCPHA) to account for the platform’s motion relative to a stationary frame of reference. It is intended to avoid overly restrictive hazard assessments that can result when motion is ignored, while ensuring safety for stationary and neighbouring moving observers.
Key topics and technical requirements
- Scope and applicability: Applies to all laser products with apertures on a moving platform (examples in the TS include vehicles, aircraft, boats and trains).
- VCPHA concept: Defines the closest point of human access that depends on platform velocity. The swept volume of the platform over a defined time window is excluded as a location where persons are reasonably expected to be present; the boundary of that swept volume is used as the VCPHA.
- Core parameters:
- v (moving platform velocity) - a velocity vector averaged over the time period tmove.
- tmove - the time interval used to compute the swept distance.
- δ = v · tmove - distance used to determine the VCPHA; a maximum δmax limits the effect of velocity.
- Stationary and moving apertures: The standard requires consideration of both apertures moving with the platform and stationary apertures (e.g., pedestrians or infrastructure), and neighbouring moving platforms whose relative speed may be near zero.
- Measurement & classification: All IEC 60825-1:2014 classification principles apply; IEC TS 60825-19 supplements clause 5 of IEC 60825-1 with the VCPHA evaluation method. Reference measurement distances and measurement reference points remain per IEC 60825-1 (see its Tables 10 and 11).
- Supporting content: Includes engineering specifications, labelling/user information requirements, and Annex A with flowcharts and examples for classification.
Applications and who should use it
- Manufacturers and integrators of platform-mounted laser systems: LIDAR, rangefinders, optical sensors on vehicles, aircraft, boats, trains, and other mobile platforms.
- Laser safety officers and test laboratories performing product classification and conformity assessment.
- System designers and regulators assessing operational scenarios where platform motion affects accessible emission and human exposure.
- Product certifiers preparing documentation, labels and user instructions consistent with moving-platform use-cases.
Related standards
- IEC 60825-1:2014 - Safety of laser products - Part 1: equipment classification and requirements (normative reference for measurement points and classification rules).
- Use both documents together when assessing platform-mounted laser products to balance realistic exposure scenarios with required safety protections.

INTRODUCTION
Laser products are sometimes used on moving platforms. Currently the standard
IEC 60825-1:2014 considers only a stationary aperture; it does not address the situations where
the emitting aperture is mounted on a platform, such as a vehicle, that can be in motion. Failure
to consider the effects of the motion of the platform can result in overly restrictive assessment
of the hazard.
Although accounting for a platform’s movement during the assessment of a laser product’s
classification can lead to less restrictive measurement conditions, it is important not to overlook
that there can be apertures, even on other moving platforms, moving at a relative speed of zero
or close to zero with respect to the moving platform laser product being classified.

that the inherent kinetic hazard of the moving platform creates a zone in which persons would
not be reasonably expected to be located. Additionally, it takes neighbouring moving platforms
into account by defining stationary and moving apertures.
This document is applicable to all laser products whose laser apertures are on a moving
platform.

Die Norm IEC TS 60825-19:2024 bietet essentielle Richtlinien für die Sicherheit von Laserprodukten, die auf beweglichen Plattformen eingesetzt werden. Der Umfang der Norm ist klar definiert und behandelt die geschwindigkeitsabhängigen nächstgelegenen Zugangsstellen für Menschen (VCPHA), was für die Klassifizierung von Laserprodukten auf beweglichen Plattformen von entscheidender Bedeutung ist. Diese Berücksichtigung richtet sich nach der Bewegung der Plattform im Verhältnis zu einem stationären Bezugssystem und erkennt die inhärente kinetische Gefährdung an, die sich aus der Bewegung der Plattform ergibt. Ein herausragendes Merkmal dieser Norm ist, dass sie dabei hilft, eine Gefahrenzone zu definieren, in der sich Personen nicht vernünftigerweise aufhalten würden. Dies ist besonders relevant, da es in der Praxis oft Situationen gibt, in denen die Laseröffnung auf einem beweglichen Gerät, wie einem Fahrzeug, montiert ist. Die Norm trifft auf alle Laserprodukte zu, deren Öffnungen sich auf einer beweglichen Plattform befinden, und stellt somit sicher, dass spezifische Sicherheitsanforderungen in diesen Kontexten angemessen berücksichtigt werden. Ein weiterer Stärkepunkt der IEC TS 60825-19:2024 ist die Berücksichtigung benachbarter beweglicher Plattformen. Die Definition von stationären und beweglichen Öffnungen ist entscheidend, um potenzielle Risiken beim Betrieb von Laserprodukten genau zu bewerten. Dies ermöglicht es, bewegliche Plattformen nicht nur isoliert, sondern auch im Zusammenspiel mit anderen beweglichen Elementen zu betrachten, was zu einer akkurateren Risikobewertung führt. Die Norm bietet somit sowohl eine Erleichterung als auch eine Präzisierung bei der Klassifizierung von Laserprodukten, indem sie vermeidet, dass aufgrund einer zu strengen Interpretation der Gefahrenlage unnötige Einschränkungen in der Bewertung der Laserprodukte auf beweglichen Plattformen entstehen. Die fundierte Herangehensweise an die Bewegung der Plattform ist unerlässlich, da dies zu weniger restriktiven Messbedingungen führen kann, ohne die Sicherheit zu gefährden. Insgesamt ist die IEC TS 60825-19:2024 ein wichtiger Schritt zur Verbesserung der Sicherheitsstandards für Laserprodukte auf beweglichen Plattformen, indem sie kritische Aspekte der Bewegungsdynamik in die Bewertungsmethoden integriert. Dies macht die Norm besonders relevant für Hersteller und Anwender von Laserprodukten, die in dynamischen Umgebungen eingesetzt werden.
IEC TS 60825-19:2024는 이동 플랫폼 레이저 제품의 안전성을 규명하기 위한 표준으로, 인간 접근의 속도 의존적 최단 거리 포인트(VCPHA)를 명시하고 있습니다. 이 표준은 이동 플랫폼이 고정된 기준 프레임에 대해 움직일 때 적용되는 레이저 제품의 분류를 위한 기준을 제공합니다. 특히, 이동 플랫폼의 고유한 동적 위험 요소가 존재하는 지역을 고려하여 사람들이 합리적으로 위치할 것으로 예상되지 않는 구역을 정의하는 것이 매우 중요합니다. 이 표준의 가장 큰 강점 중 하나는 이웃하는 이동 플랫폼을 고려하여 정지 및 이동 개구부를 명확히 정의한다는 점입니다. 이는 레이저 제품이 이동 플랫폼에 장착된 경우 발생할 수 있는 위험을 보다 정확하게 평가할 수 있도록 돕습니다. 현재까지의 IEC 60825-1:2014는 정지 개구부만을 고려하고 있었으므로, 실제 이동 플랫폼에서의 레이저 제품 운용 시 발생할 수 있는 다양한 상황을 충분히 반영하지 못했습니다. 이동 플랫폼의 운동을 레이저 제품 분류 평가 시 반영함으로써 보다 유연한 측정 조건을 적용할 수 있는 가능성이 열리지만, 다른 이동 플랫폼에서 상대 속도가 0 또는 거의 제로인 개구부의 영향을 간과하지 않는 것도 중요합니다. 이는 안전성을 평가하는 데 있어 중요한 요소로 작용할 수 있습니다. IEC TS 60825-19:2024는 레이저 제품의 안전 기준을 담고 있으며, 특히 이동 플랫폼과 관련된 새로운 요구사항을 충족시키기 위한 현대적이고 실용적인 표준으로 그 의의가 매우 큽니다. 따라서 이 표준은 레이저 제품의 안전성을 평가하고 인증하는 데 있어 필수적인 자료로 자리잡을 것입니다.
The IEC TS 60825-19:2024 standard addresses a critical aspect of laser safety specific to moving platform laser products. Its well-defined scope establishes velocity-dependent closest points of human access (VCPHA), which is fundamental in classifying laser products mounted on platforms that are in motion. By considering the kinetic hazards associated with moving platforms, this standard effectively creates a framework that recognizes the unique risks posed by laser products in dynamic environments, an area that was previously inadequately covered by IEC 60825-1:2014, which focused solely on stationary apertures. One of the key strengths of IEC TS 60825-19:2024 is its acknowledgement of various operational contexts for laser products. It addresses the potential hazards of not just the primary moving platform but also neighboring platforms, accommodating scenarios where laser apertures on other moving devices might be in proximity. This holistic approach is crucial for ensuring comprehensive safety assessments in environments where multiple dynamic elements interact. Moreover, the standard's methodology allows for less restrictive measurements compared to traditional classifications that do not consider platform movement. This flexibility is vital for innovation within the laser industry, permitting safer deployment of laser technologies in vehicles and other mobile applications. The inclusion of definitions for stationary and moving apertures further enhances clarity and usability for practitioners assessing laser hazards. In conclusion, the IEC TS 60825-19:2024 standard solidifies its relevance in today’s fast-paced technological landscape. By incorporating kinetic considerations into laser safety classifications and addressing previously overlooked scenarios, it stands as an essential reference for manufacturers and users of moving platform laser products, ensuring that safety protocols evolve alongside advancements in laser technology.
La norme IEC TS 60825-19:2024 constitue une avancée significative dans le domaine de la sécurité des produits laser, en se concentrant spécifiquement sur les produits laser montés sur des plateformes mobiles. Son champ d'application est clair et précis, visant à établir des critères de classement basés sur les points d'accès humain les plus proches dépendant de la vitesse (VCPHA). Ce cadre est essentiel pour garantir que les risques potentiels liés à la dynamique des plateformes mobiles soient évalués de manière appropriée. L'un des principaux atouts de cette norme est qu'elle reconnaît l'importance de la situation dans laquelle un produit laser peut être utilisé, notamment lorsqu'il est intégré à des véhicules en mouvement. Contrairement à la norme précédente IEC 60825-1:2014, qui se limite à des ouvertures stationnaires, IEC TS 60825-19:2024 brode une analyse qui tient compte des scénarios réels d'utilisation où la dynamique de la plateforme peut influencer l'évaluation du danger. Cela permet d'éviter des classifications inappropriées et trop restrictives des risques associés. De plus, la norme met en lumière l'importance de prendre en compte non seulement la plateforme mobile elle-même, mais aussi d'autres plateformes pouvant être à proximité, augmentant ainsi la précision de l'évaluation des risques. Cela souligne la pertinence de la norme dans un environnement où les produits laser sont souvent utilisés dans des configurations complexes et mobiles. En intégrant ces éléments, IEC TS 60825-19:2024 s'avère non seulement pertinente mais aussi essentielle, offrant un cadre qui garantit une évaluation équilibrée et réfléchie des dangers associés. Cette norme répond aux besoins de l'industrie en matière de sécurité tout en facilitant l'innovation dans l'utilisation des produits laser sur des plateformes mobiles, ce qui est crucial pour les développements futurs dans ce secteur.
IEC TS 60825-19:2024は、移動プラットフォームレーザー製品の安全性に関する標準であり、その適用範囲は、静止した基準枠に対するプラットフォームの動きに基づく人間のアクセスの最も近いポイントに依存する速度を考慮しています。この標準は、移動プラットフォームが内在的な運動危険を生じさせ、そのために人が存在することが合理的に期待されないゾーンを形成することを前提としており、特にその周囲の移動プラットフォームを考慮に入れた固定および移動するアパーチャーの定義がなされています。 特に、移動プラットフォーム上で使用されるレーザー製品の分類においては、既存のIEC 60825-1:2014が静止アパーチャーのみを考慮している点と比較し、IEC TS 60825-19:2024は動くアパーチャーを持つ状況、つまり車両や他の移動プラットフォームに搭載されたレーザー発信源の評価がいかに重要かを強調しています。この標準の導入により、プラットフォームの動きを考慮することで、危険の評価が過度に制限される事態を回避できることが示されています。 また、異なる移動プラットフォームにおける相対的な速度がゼロまたはそれに近い場合でも、アパーチャーの影響を無視することはできません。この点を考慮に入れることで、移動プラットフォームレーザー製品の安全性評価がより現実的で信頼性のあるものになるでしょう。この標準が持つ強みは、レーザー製品の使用の安全性を向上させ、関連するリスクを適切に評価できるため、多くの産業分野での適用が期待される点にあります。 総じて、IEC TS 60825-19:2024は、移動プラットフォーム上でのレーザー製品に関する技術的なガイドラインを提供し、製品の安全性向上に寄与する非常に重要な標準であると言えます。これにより、レーザー技術の進化に合わせた安全基準の確立が促進されるでしょう。
