Eye and face protection for occupational use —

Part 1: General requirements

1 Scope

This document specifies general requirements for eye and face protectors. These protectors are intended to provide protection for the eyes and faces of persons against one or more common occupational hazards such as impacts from flying particles and fragments, optical radiation, dusts, splashing liquids, molten metals, heat, flame, hot solids, harmful gases, vapours and aerosols.

Additional requirements for eye and face protectors used during welding and related techniques and for mesh protectors are given in ISO 16321-2 and ISO 16321-3, respectively.

This document applies to:

— all plano as well as corrective and prescription lensed protectors and components;

— those eye and face protectors used for occupational-type tasks that are performed similarly to an occupation, e.g. "do-it-yourself";

— those eye and face protectors used in educational establishments.

This document does not apply to:

— protectors specifically intended for protection against only solar radiation and used in non- occupational environments for which the ISO 12312 series applies;

— protectors for medically prescribed applications (not occupational), e.g. eye protection for severe dry eye, tints prescribed for medical conditions;

— patient eye protectors during diagnosis or treatment (e.g. ISO/TR 22463);

— protectors for use during medical or e.g. aesthetic applications, e.g. intense light sources (ILS) for which the ISO 12609 series applies;

— protectors specifically intended for sports for which the ISO 18527 series applies;

— laser protectors;

— face protectors intended for live-working to protect against short-circuit electric arcs for which IEC 62819 applies;

— protectors intended to protect against ionizing radiation, e.g. X-rays, for which IEC 61331-3 applies.

4.1 Ambient temperatures

1)

Protectors described in this document are intended for use at normal ambient temperatures (23 ± 5) °C. In order to ensure that critical aspects of protection are not compromised due to temperatures towards the extremes of the normal range of occupational environments from (−5 ± 2) °C to (+55 ± 2) °C, physical and mechanical requirements at extremes of temperature are included (sometimes optionally) in this document. These physical and mechanical requirements can also be provided by manufacturers for validation of claims for protection at temperatures below (−5 ± 2) °C and/or above (+55 ± 2) °C.

4.2 Physiological compatibility

Protectors shall be designed and manufactured in such a way that, when used under the conditions and for the purposes intended, they will not compromise the health or safety of the wearer. The risks posed by substances leaking or evaporating from the protector that can come into prolonged contact with the wearer, shall be reduced by the manufacturer to within the limits of any applicable regulatory requirement.

1) For the purposes of this document, “protector” is used as a general term for eye and/or face protectors such as, but not limited to, spectacles, goggles, face shields and eye shields.
