CEN/TC 85/WG 3 - Eye protectors against laser radiations

This document is applicable to protectors intended to provide protection against accidental exposure to laser radiation within the wavelength range 180 nm to 1 mm. It specifies the requirements, test methods and marking. Protectors intended for adjustment work on lasers are included in the scope of this document and are marked in the same way as other protectors, but selection of appropriate eyewear for a specific application is a choice of the user. Laser protective filters used as viewing windows in laser equipment machinery or incorporated into optical instruments such as operating microscopes and loupes that may be used for deliberate viewing of laser radiation as part of their function are outside the scope of this document.
Laser radiation in the wavelength range below 180 nm is absorbed in air, therefore eye and face protection should not be required.
This document is applicable to devices intended for patient protection during medical laser procedures except for treatment in the periorbital area. Guidance on eye protectors for patients (including those used for periorbital treatment) is given in ISO/TR 22463.

This European Standard applies to eye-protectors used for protection against accidental exposure to laser radiation as defined in EN 60825-1:2007 in the spectral range 180 nm (0,18 µm) to 1 000 µm. It defines the requirements, test methods and marking. A guide is given in Annex B for the selection and use of laser eye protectors.
This European Standard does not apply to protectors for intentional exposure to laser radiation.
EN 208 applies for laser adjustment eye-protectors.
Before selecting eye protection according to this European Standard, a risk assessment should first be undertaken (see Annex B).

This European Standard specifies functional requirements and a product labelling applicable to temporary and permanent passive guards (in the following called screens) for protection against laser radiation. This standard includes test methods for testing functional performance and the specification of the user documentation to be supplied with the product. The screens are designed to protect the user from: unintentional exposure to direct and/or diffuse laser radiation; a time limited exposure to laser radiation, based on the functional requirements determined by risk assessment. This European Standard applies to supervised screens for installations in working places at which laser radiation up to a maximum mean power of 100 W or single pulse energy of 30 J occurs within the spectral range between 180 nm (0,18 μm) and 106 nm (1 000 μm). This European Standard applies to the protection against laser radiation only. This standard does not apply to other hazards including hazards from secondary radiation that can arise during, for example, material processing. This European Standard gives guidance on how to select such screens. Laser enclosures and housings that are supplied as part of the laser product or are supplied to be fitted to a laser system to form a laser product (according to EN 60825-1) are not considered to be within the scope of the standard.

This European Standard applies to laser adjustment filters and eye-protectors. These are filters and eye-protectors for use in adjustment work on lasers and laser systems as defined in EN 60825-1:2007 where hazardous radiation occurs in the visible spectral range of 400 nm to 700 nm. Filters specified in this European Standard reduce this radiation to values defined for lasers of class 2 (<= 1 mW for CW (continuous wave) lasers).
This European Standard defines the requirements, test methods and marking. A guide is given in Annex B with regard to selection and use.
EN 207 applies to eye-protection against accidental exposure to laser radiation.
NOTE   Before selecting eye protection according to this European Standard a risk assessment should first be undertaken (see Annex B).

This standard specifies functional requirements and a product labelling applicable to temporary and permanent passive guards (in the following called screens) for protection against laser radiation. This standard includes test methods for testing functional performance and the specification of the user documentation to be supplied with the product. The screens are designed to protect the user from:
-   unintentional exposure to direct and/or diffuse laser radiation;
-   a time limited exposure to laser radiation, based on the functional requirements determined by risk assessment.

This european standard applies to laser adjustment filters and eye-protectors. These are filters and eye-protectors for use in adjustment work on lasers and laser systems as defined in EN 60825-1:1994 (i.e. LED (Light Emitting Diode) radiation is included) where hazardous radiation occurs in the visible spectral range of 400 nm to 700 nm. Filters specified in this standard reduce this radiation to values defined for lasers of class 2 (< 1 mW for CW (Continuous wave) lasers). In this case aversion responses including the blink reflex contribute to eye protection.  This standard defines the requirements, test methods and marking. A guide is given in annex B with regard to selection and use.  EN 207 applies to eye-protection against laser radiation where aversion responses including the blink reflex is not stipulated and laser radiation outside the visible spectral range.  NOTE: Before selecting eye protection according to this standard a risk assessment should first be undertaken (see annex B).

This European Standard applies to eye-protectors used for protection against laser radiation as defined in EN 60825-1:1994 (i.e. LED (Light Emitting Diode) radiation is included) in the spectral range 180 nm (0,18 æm) to 1 000 æm. It defines the requirements, test methods and marking. A guide is given in annex B with regard to selection and use.  EN 208 applies for laser adjustment eye-protectors.  NOTE : Before selecting eye protection according to this standard a risk assessment should first be undertaken (see annex B).

This standard specifies functional requirements and a product labelling system applicable to a range of temporary and permanent passive guards (in the following called screens) for protection against laser radiation. This standard includes test methods for testing functional performance and also the specification of the user documentation to be supplied with the product. The screens are designed to protect the user from uncontrolled emission of direct and/or diffuse radiation for a defined exposure to lasers, based on the necessary functional requirements for any particular application being determined by risk assessment principles.  This standard applies to supervised screens for installations in working places at which laser radiation up to a maximum mean power of 100 W or single pulse energy of 30 J occurs within the spectral range between 180 nm (0,18 æm) and 106 nm (1000 æm).  This standard applies to the protection against laser radiation only. This standard does not apply to other hazards including hazards from secondary radiation that can arise during, for example, material processing.  This standard gives guidance on how to select such screens.  The following are not considered to be within the scope of the standard:  - laser enclosures and housings that are supplied as part of the laser product or are supplied to be fitted to a laser system to form a laser product (according to IEC 60 825-1:1998);  - any screen whose protective properties are limited to a restricted range of angles of incidence (e.g. some interference filters).
