14、has been prepared by Technical Committee CEN/TC 85, “Eye-protective equipment“, the secretariat of which is held by AFNOR. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by May 2002, and conflicting

15、 national standards shall be withdrawn at the latest by May 2002. This European Standard replaces EN 166:1995. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s). For

16、relationship with EU Directive(s), see informative annex ZA, which is an integral part of this document. According to the CENKENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Czech Republic,

17、Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom. 3 EN 166:2001 (E) 1 Scope This European Standard specifies functional requirements for various types of personal eye-protectors and incorp

18、orates general considerations such as: - designation; - classification; - basic requirements applicable to all eye-protectors; - various particular and optional requirements; - allocation of requirements, testing and application; - marking; - information for users. The transmittance requirements for

19、 various types of filter oculars are given in separate standards (see clause 2). This European Standard applies to all types of personal eye-protectors used against various hazards, as encountered in industry, laboratories, educational establishments, DIY activities, etc. which are likely to damage

20、the eye or impair vision, with the exception of nuclear radiation, X-rays, laser beams and low temperature infrared (IR) radiation emitted by low temperature sources. The requirements of this standard do not apply to eye-protectors for which separate and complete standards exist, such as laser eye-p

21、rotectors, sunglasses for general use, etc. unless such standards make specific reference to this standard. The requirements of this standard apply to oculars for welding and allied processes but do not apply to equipment for eye and face protection for welding and allied processes, requirements for

22、 which are contained in EN 175. Eye-protectors fitted with prescription lenses are not excluded from the field of application. The refractive power tolerances and other special characteristics dependent upon the prescription requirement are specified in EN IS0 8980-1 and EN IS0 8980-2. 2 Normative r

These normative references are cited at the appropriate places in the text, and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any o

30、 clause 17 of EN 168:2001 when the eye-protector is fitted to it in accordance with the manufacturers instructions 4 Classification 4.1 Function of eye-protectors The function of eye-protectors is to provide protection against: - impacts of different severities; - optical radiations; - molten metals

31、 and hot solids: - droplets and splashes; - dst; - gases; - short circuit electric arc; or any combination of these. 4.2 Types of eye-protectors NOTE 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.

34、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. They may also have coatings on their surface(s) to give additional characteristics. 5 Designation of filters The transmittance characteristics of a filter

35、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 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
