17、m . Page 3 EN 166 : 2001 1 Scope This European Standard specifies functional requirements for various types of personal eye-protectors and incorporates general considerations such as: - designation; - classification; - basic requirements applicable to all eye-protectors; - various particular and opt

18、ional requirements; - allocation of requirements, testing and application; - marking; - information for users. The transmittance requirements for various types of filter oculars are given in separate standards (see clause 2). This European Standard applies to all types of personal eye-protectors use

19、d against various hazards, as encountered in industry, laboratories, educational establishments, DIY activities, etc. which are likely to damage the eye or impair vision, with the exception of nuclear radiation, X-rays, laser beams and low temperature infrared (IR) radiation emitted by low temperatu

20、re sources. The requirements of this standard do not apply to eye-protectors for which separate and complete standards exist, such as laser eye-protectors, sunglasses for general use, etc. unless such standards make specific reference to this standard. The requirements of this standard apply to ocul

21、ars for welding and allied processes but do not apply to equipment for eye and face protection for welding and allied processes, requirements for which are contained in EN 175. Eye-protectors fitted with prescription lenses are not excluded from the field of application. The refractive power toleran

22、ces and other special characteristics dependent upon the prescription requirement are specified in EN IS0 8980-1 and EN IS0 8980-2. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at th

23、e appropriate places in the text, and the publications are listed hereafter.

30、ye-protectors The function of eye-protectors is to provide protection against: - impacts of different severities; - optical radiations; - molten metals and hot solids; - droplets and splashes; - dst; - gases; - short circuit electric arc: or any combination of these. 4.2 Types of eye-protectors NOTE

31、 Refer to definitions given in EN 165. 4.2.1 Spectacles with or without lateral protection 4.2.2 Goggles 4.2.3 Face-shields NOTE mounting device.

33、rs made in multiple layers joined together by a binder. NOTE All types of oculars may be further classified into filtering types (for example according to EN 169, EN 170, EN 171, EN 172 and EN 379). They may also be classified as oculars with corrective effect and oculars without corrective effect.

34、They may also have coatings on their surface(s) to give additional characteristics. 5 Designation of filters The transmittance characteristics of a filter are represented by a scale number. The scale number is a combination of the code number and the shade number of the filter, joined together by a

35、dash. The scale number for welding filters does not include a code number, it comprises the shade number only. Table 1 gives the designation of the various types of filters specified in this European Standard. Page 6 EN 166 : 2001 Table 1 - Scale numbers for filters Welding filters I Ultraviolet fil
