UV erythema in the workplace
Regulation: EU Directive 2006/25/EC, erythemal dose (SED)
UV erythema is the acute reddening of the skin after an excessive UV dose, especially for outdoor work or at UV installations. The article explains causes, exposure limits and protective measures and when recurring erythema is a warning sign.
Safety of UV disinfection
Regulation: Product Safety Act, EN 62471, exposure limit values
UVB and UVC radiation inactivates viruses and micro-organisms, but damages skin and eyes just the same. The article covers exposure time, dose and product safety law for disinfection devices on surfaces, in air and on people.
Occupational Safety & Photobiological Safety
Measurand: effect-weighted irradiance, exposure limit value
Artificial optical radiation from lamps, LEDs and installations can damage skin and eyes photochemically or thermally. The article explains effect-weighted assessment under 2006/25/EC and EN 62471 at a realistic measurement geometry.
Guidelines, norms & standards
Regulation: EN 62471, IEC 60335, 2006/25/EC, DIN 5031, ISO/IEC 17025
Two strands of regulation apply to UV radiation: product safety and occupational safety. The article places EN 62471, IEC 60335, the occupational safety directive and the calibration standards and shows which rule applies when.
RoHS and UV lamps - current regulations and developments
Short answer: UV lamps stay permitted via Annex III exemptions – for now
The RoHS Directive restricts mercury in electrical equipment; UV lamps rely on time-limited exemptions in Annex III. The article summarises the current status of the exemptions and what they mean for existing stock and new purchases.
PFAS - Relevance for UV sensors, UV systems and UV measurement technology
Short answer: seals and cables are affected, not the measuring function
Per- and polyfluoroalkyl substances (PFAS) are extremely stable – hence widespread in seals, cables and coatings and at the same time under discussion for a ban. The article assesses the relevance for UV sensors and UV systems.
Machinery Regulation & Cyber Resilience Act
Regulation: Regulation (EU) 2023/1230, Cyber Resilience Act (EU) 2024/2847
On 20 January 2027 Regulation (EU) 2023/1230 replaces the Machinery Directive, with the Cyber Resilience Act alongside. The article clarifies the definition of machinery, protection against corruption and when the UV dose is a safety function.
UV processes & regulation
Regulation: GMP, ISO 9001, ISO/IEC 17025, Machinery Regulation
As regulatory control of manufacturing tightens, UV measurement turns from a tool into evidence. The article places validation, monitoring, calibration and documentation within the German and European framework.
