6 European foreword This document (pren 14458:2016) has been prepared by Technical Committee CEN/TC 85 Eye protective equipment, the secretariat of which is held by AFNOR. This document is currently submitted to the CEN Enquiry. This document will supersede EN 14458: 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 relationship with EU Directive(s), see informative Annex ZA which is an integral part of this document. 4

7 1 Scope This European Standard specifies the minimum requirements for visors designed specifically to be used only with protective helmets, including but not limited to those conforming to EN 443, EN 14052, EN and EN as the situation dictates. These visors may be permanently fitted to, or removable from, the helmet. See the scope of the various helmet standards for applications. These visors are not intended to protect against smoke and gas /vapour hazards. Three types of visors in two forms are described in this document. The two forms are: face guards provide both eye and face protection, and eye guards that are shorter and effectively provide only eye protection. The three types are: Visors for general use: Eye guards and face guards providing resistance and/or protection against mechanical, liquid chemical and basic physical hazards. Visors with increased thermal performance: Face guards that additionally provide resistance and/or protection against higher than basic levels of heat and flame. This additional requirement is not applicable for eye guards. Mesh visors: Eye guards and face guards that incorporate mesh oculars with defined levels of performance from EN 1731, and other additional mechanical requirements described in this standard. Visors for sporting use, those with corrective effect, and goggles used with a protective helmet are not covered by this standard. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

9 4 Classification 4.1 General Visors according to this document shall be classified as one of three types. Specific warning shall be included in the information provided by the manufacturer on the limitations on use of each type (see Clause 8 g)), and the need to ensure that suitable helmet-visor combinations are used (see Clause 8 n)). Table 1 outlines the clauses of this standard applicable to the three types of visors.
