28、orming to EN 14052. These visors may be permanently fitted to, or be removable from the helmet.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 prote

29、ction.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 h

30、igher than basic levels of heat and flame; mesh visors: eye guards and face guards that incorporate mesh lenses with defined levels of performance from EN 1731, and other additional mechanical requirements described in this European Standard.These visors are not intended to protect against smoke and

31、 gas /vapour hazards.Visors for sporting use, those with corrective effect, and goggles used with a protective helmet are not covered by this European Standard.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for it
