EN IEC 62471-6:2023

Photobiological safety of lamps and lamp systems - Part 6: Ultraviolet lamp products

This Standard provides the optical radiation safety requirements for ultraviolet lamp products, including UV LED products. This standard provides requirements for: - optical radiation safety assessment and ultraviolet-product risk groups; - user information for safety measures; - appropriate labelling of ultraviolet lamp products This standard addresses those lamps and lamp products where the ultraviolet emission serves the primary purpose of the product and where more than half of the optical radiation emitted between 180 nm - 3 000 nm is in the spectral region 180 nm - 400 nm. If more than half of the optical radiation emitted between 180 nm - 3 000 nm is outside of the spectral region 180 nm - 400 nm, then the base standard IEC 62471-1 should be used. This standard covers medical diagnostic devices/products that emit primarily UV radiation. Because photobiological effects from UV radiation are based on the total accumulated exposure (dose) received, this standard relies on the concept of ‘Time-weighted Average’ exposures where the assessment distance for determining the RG is chosen based on realistic exposure distances and exposure durations. In other words, it is not expected that people will be exposed at very close distances, e.g. 20 - 30 cm, for extended periods of time. This standard is needed to provide assessment distances and specific guidance that are application-specific and realistic rather than the more general values in IEC 62471 where the specific application is unknown and time-weighted average exposures are not application-specific. This Standard does not provide requirements for: - lamps which primarily emit visible and/or infrared radiant energy - lamp products used for general lighting or infrared illumination or heating, which are treated in separate standards. - fluorescent ultraviolet lamps for tanning (covered by IEC 60335-2-27 and IEC 61228). - medical treatment devices/products (see IEC 60601-2-57), but covers UV medical diagnostic products.

Photobiologische Sicherheit von Lampen und Lampensystemen - Teil 6: Produkte mit ultravioletter Strahlung

Sécurité photobiologique des lampes et des appareils utilisant des lampes - Partie 6: Appareils à lampes ultraviolettes

IEC 62471-6:2022 IEC 62471:2006/CIE S009:2002. La norme CEI 62471 couvre les diodes électroluminescentes (DEL), les lampes à incandescence, à décharge de gaz à basse et haute pression, les lampes à arc et autres. Il couvre également les lampes conçues principalement pour émettre de l’énergie rayonnante ultraviolette, telles que les sources ultraviolettes destinées à exciter la fluorescence des matériaux irradiés, pour les pièges à insectes, pour les études scientifiques, l’identification des minéraux, les essais non destructifs, l’irradiation germicide et à d’autres fins. La présente partie de la CEI 62471 fournit les exigences de sécurité contre le rayonnement optique pour les lampes ultraviolettes, y compris les lampes UV LED. Le présent document prévoit des exigences pour :
l’évaluation de la sûreté des rayonnements optiques et les groupes à risque de produits ultraviolets;
les renseignements sur l’utilisateur pour les mesures de sécurité;
l’étiquetage approprié des produits de lampes ultraviolettes.  Le présent document traite des lampes et des produits de lampes dont l’émission ultraviolette sert l’objectif principal du produit et où plus de la moitié de la puissance rayonnante émise entre 180 nm et 3 000 nm se trouve dans la région spectrale de 180 nm à 400 nm. Si plus de la moitié du rayonnement optique émis entre 180 nm et 3 000 nm se trouve en dehors de la région spectrale de 180 nm à 400 nm, il convient d’utiliser la norme de base IEC 62471. Ce document couvre les dispositifs/produits de diagnostic médical et cosmétiques qui émettent principalement des rayons UV.

Fotobiološka varnost ultravijoličnih sijalk

Ta standard podaja zahteve v zvezi z varnostjo pri optičnem sevanju za ultravijolične sijalke, vključno z izdelki UV-LED.
Standard podaja zahteve za:
– oceno varnosti pri optičnem sevanju in tvegane skupine ultravijoličnih izdelkov;
– informacije za uporabnike o varnostnih ukrepih;
– ustrezno označevanje ultravijoličnih sijalk.
Ta standard obravnava sijalke in izdelke s sijalkami, pri katerih je ultravijolično sevanje prvotni namen izdelka in je več kot polovica optičnega sevanja, ki se oddaja v razponu od 180 nm do 3000 nm, v spektralnem območju od 180 nm do 400 nm. Če je več kot polovica optičnega sevanja, ki se oddaja v razponu od 180 nm do 3000 nm, zunaj spektralnega območja od 180 nm do 400 nm, je priporočljivo uporabiti osnovni standard IEC 62471-1. Ta standard obravnava diagnostične medicinske pripomočke/izdelke, ki oddajajo predvsem ultravijolično sevanje.
Fotobiološki učinki UV-sevanja temeljijo na skupni prejeti izpostavljenosti (odmerku), zato se ta standard navezuje na koncept »časovno obtežene povprečne« izpostavljenosti, pri katerem je ocenjevalna razdalja za določanje RG izbrana na podlagi realnih razdalj izpostavljenosti in njenega trajanja. Tako ni pričakovati, da bodo ljudje dlje časa izpostavljeni na zelo majhnih razdaljah (npr. 20–30 cm). Ta standard je potreben za zagotavljanje ocenjevalnih razdalj in posebnih smernic, ki so specifične za vrsto uporabe in realistične – za razliko od splošnejših vrednosti v standardu IEC 62471, pri katerih posebna vrsta uporabe ni znana in časovno obtežena povprečna izpostavljenost ni specifična za vrsto uporabe.
Standard ne podaja zahtev za:
– sijalke, ki oddajajo predvsem vidno in/ali infrardečo sevalno energijo;
– izdelke s sijalkami, ki se uporabljajo za splošno razsvetljavo, infrardečo osvetlitev ali ogrevanje (obravnavani so v ločenih standardih);
– fluorescenčne ultravijolične sijalke za umetno sončenje (zajete v standardih IEC 60335-2-27 in IEC 61228);
– medicinske pripomočke/izdelke za zdravljenje (glej standard IEC 60601-2-57), vendar zajema ultravijolične diagnostične medicinske izdelke.
