CAN/CSA-Z94.3-99

1. Scope 1.1 This Standard applies to eye and face protectors used in all occupational and educational operations or processes involving hazards to the eyes or face. Typical hazards include flying objects and particles, splashing liquids, molten metal, and ultraviolet, visible, and infrared radiation, but do not include X-rays, gamma rays, high-energy particulate radiation, radioactive materials, lasers, or masers. Note: It is recommended that the guidelines for protection outlined in Appendix A be followed when similar potentially hazardous activities are conducted in the home, at leisure, and in recreational environments. For certain sports activities, other Standards should be consulted, eg, CSA Standard P400 for racquet sports and CAN/CSA-Z262.2 for ice hockey. 1.2 This Standard sets minimum performance requirements in the tests described herein, but does not cover other factors of design such as comfort, service life, or appearance. Note: The conformance of protectors with these requirements does not imply equality of their performance, nor should it be interpreted to mean that protectors are capable of affording greater than is specified in this Standard. 1.3 In this Standard, the use of the word "shall" indicates a mandatory requirement. The word "should" indicates a recommendation, and the word "may" is used to express permissible alternatives.
