Full title and description

STB DIN 5031-10:2018-03 — Optical radiation physics and illuminating engineering — Part 10: Photobiologically effective radiation, quantities, symbols and action spectra. This German national standard defines quantities, symbols and action spectra used to evaluate photobiological and thermal effects of optical radiation.

Abstract

DIN 5031-10:2018-03 specifies action spectra and related physical quantities and symbols for assessing photobiological and thermal effects of optical radiation on biological tissue (eye and skin). It notes limited coverage of phototherapeutic and photosensitizing effects, excludes photometric and colorimetric effects, and is not intended to establish workplace exposure limits.

General information

• Status: Current / Active.
• Publication date: 2018-03-01 (edition: 2018-03).
• Publisher: Deutsches Institut für Normung (DIN).
• ICS / categories: 17.180.01 (Optics and optical measurements in general).
• Edition / version: Edition 2018-03 (replaces DIN 5031-10:2013-01).
• Number of pages: 102 (document page counts reported as ~102–104 depending on distributor).

Scope

The standard defines the action spectra and the spectral weighting functions used to quantify photobiological (including photochemical) and thermal effects caused by optical radiation in the spectral range covered. It provides standard quantities and short notations for use in measurements and reporting, and clarifies which photobiological effects are within its remit and which are outside (for example, it does not provide workplace exposure limits or cover photometric/colorimetric assessment).

Key topics and requirements

• Definitions of photobiologically relevant quantities and their symbols (radiant exposure, irradiance, spectral weighting, etc.).
• Standard action spectra for evaluating photochemical and thermal effects on skin and eye.
• Procedures for applying spectral weighting functions to measured spectral irradiance or radiance.
• Guidance on limits of applicability (which phototherapeutic/photosensitizing effects are partially covered and which are excluded).
• Normative and informative references to international CIE documents and related standards used for photobiological assessment.

Typical use and users

This standard is used by lighting designers, photobiologists, manufacturers of lamps and luminaires, medical device developers (where photobiological effects must be described), testing and calibration laboratories, regulatory bodies interpreting photobiological risk, and standards committees when harmonizing action spectra and related terminology.

Related standards

Part of the DIN 5031 series on optical radiation physics and illuminating engineering. This part cites and builds on CIE technical reports and related documents (examples: various CIE technical notes and reports referenced in the standard). It replaces the 2013 edition of DIN 5031-10 and is complemented by other parts of the DIN 5031 series (and by newer parts addressing non‑visual/melanopic effects where applicable).

FAQ

Q: What is this standard?

A: DIN 5031-10:2018-03 is the DIN standard that specifies quantities, symbols and action spectra for evaluating photobiologically effective optical radiation (eye and skin effects) and associated thermal effects.

Q: What does it cover?

A: It covers definition of photobiological quantities, standardized action spectra and spectral weighting procedures to evaluate photochemical and thermal effects of optical radiation. It does not cover photometric/colorimetric effects and is not a standard for setting workplace exposure limits.

Q: Who typically uses it?

A: Lighting engineers, photobiologists, manufacturers, test laboratories, medical-device specialists (for photobiological safety/characterization) and standards bodies. It is used wherever quantitative photobiological assessment of light sources or optical systems is required.

Q: Is it current or superseded?

A: The 2018-03 edition is the current edition (it replaced the 2013 edition). Users should verify if a newer revision has been published for their specific application, but authoritative distributors list the 2018-03 edition as the active version.

Q: Is it part of a series?

A: Yes — it is Part 10 of the DIN 5031 series (Optical radiation physics and illuminating engineering). Other parts of DIN 5031 address related measurement, photometric and non‑visual/melanopic effects.

Q: What are the key keywords?

A: Action spectra; photobiological radiation; spectral weighting; irradiance; radiant exposure; photochemical effects; thermal effects; DIN 5031; CIE.
