Full title and description

Photobiological safety of lamps and lamp systems — Part 5: Image projectors. This international standard specifies a risk‑group classification system, measurement conditions and manufacturer requirements for image projectors (theatre, data, professional and home‑use projectors) to assess and limit photobiological hazards from projected optical radiation.

Abstract

IEC 62471‑5:2015 defines test conditions and measurement methods (irradiance and radiance, throw ratio, measurement distance and specified apertures), accessible emission limits for continuous and pulsed emissions, and manufacturer obligations such as labelling, user information and optional safety functions. It assigns projectors to risk groups (RG0, RG1, RG2, RG3) to support product design, compliance and occupational risk assessments.

General information

• Status: Published international standard.

• Publisher: International Electrotechnical Commission (IEC).
• ICS / categories: 29.140.01, 31.260.
• Edition / version: Edition 1.0 (2015).
• Number of pages: 51 pages.

Scope

Specifies photobiological safety requirements and measurement procedures specifically for image projectors, covering projected visible optical radiation from lamp systems and laser‑illuminated projecting systems. The standard is intended to determine projector risk groups, define test setups and measurement distances, and identify manufacturer information and safety features required when a projector is assigned to a particular risk group. It may be used to inform product safety documentation and occupational exposure assessments.

Key topics and requirements

• Risk group classification for image projectors (RG0, RG1, RG2, RG3) and the basis for those groups.
• Measurement conditions: defined throw ratio, measurement distance, apertures and procedures for determining apparent source and angular subtense.
• Irradiance and radiance measurement methods and conversion rules where required.
• Accessible emission limits (AELs) for continuous‑wave and pulsed emissions and criteria for comparison with exposure limits.
• Manufacturer requirements: labelling, user information, maintenance information, hazard‑distance determination and optional safety functions (for example “soft start” and other protective features).
• Annexes and examples: test plans, calculation examples, guidance on measurement set‑ups and special cases (included informative and normative annexes).

Typical use and users

Used by projector manufacturers, product compliance and safety engineers, independent test laboratories, standards bodies and regulatory agencies to classify projectors, perform photometric/ radiometric testing, prepare user information and implement required safety features. Also used by occupational health professionals when assessing workplace exposure to projected optical radiation.
