Preface This document is the eighth edition of CSA Z94.3, Eye and Face Protectors. It replaces the editions published in 2007 and 2002 with the same title, and the editions published in 1999, 1992, 1988, 1982 and 1969 entitled Eye and Face Protectors for Industry.  The following major changes have been made to this edition:   addition of hazard type I (lasers) and requirements for protection against laser radiation (Chapter 4 and Article 8.6) addition of hazard type J (arc flashes) and flash protection requirements (Chapter 4 and sections 8.7, 9.3.6 and 10.5) modification of the optical requirements for protective goggles fitted with flat lenses without a corrective reading segment (Article 12.6) modification of the false head used for impact and penetration tests (Articles 12.2.1, 12.11.1 and 12.13) addition of two sizes of steel balls and widening of the hardness range of the steel balls used for impact tests (Articles 6.1.3.1, 6.1.3.2 and 12.2.1.3) updated Table 5 for lens types that are presumably compliant with this standard accuracy of requirements and test procedures for ignition and flame resistance (Articles 6.2 and 12.3) clarification of impact points for face shields and welding guards (Article 12.2.2) enlargement determination of the field of vision - to take into account curved lenses (sections 8.4.1, 12.12.2 and 12.12.3) addition of Appendix F showing examples of lenses subjected to the impact test The basic behavior requirements, added in 2002, apply to all protectors covered by this standard, while the prescribed test procedures differ depending on whether they are corrective lenses or non-corrective lenses.  As in previous editions, for non-corrective eye protectors, the prescribed test procedures must be performed using the complete product (not the components). On the other hand, with respect to Category 1 protectors with corrective lenses, the behavioral requirements and test procedures apply to lenses and frames separately. This standard specifies requirements for the manufacture of these protectors (eg, quality assurance). In addition, this edition discusses the role of the ophthalmic professional in the adjustment and modification of eyeglasses. Overall, these requirements allow for the assessment of compliance of corrective lens goggles.  Domain of 1.1 This Standard deals with eye and face protectors used at work and in educational and vocational schools during activities that may lead to eye and face injuries. Typical accidents are caused by particles or projected objects, splashes of liquids or molten metals, ultraviolet, visible and infrared radiation. The standard does not include accidents caused by X-rays, gamma rays, particulate matter radiation, radioactive materials or masers.  Note:  The Schedule A guidelines should be followed when engaging in activities at home, in recreation or for certain sports that may be hazardous. However, other standards should be consulted for certain sporting activities (eg CSA Z262.2).  1.2 This standard establishes the minimum performance requirements for eye and face protector testing, but does not address design factors such as the comfort, useful life or aesthetics of these protectors.  Note:  Protectors' compliance with these requirements does not mean that they all exhibit the same behavior or that they can provide greater protection than that specified in this standard.  In this standard, the word "must" indicates a requirement, that is, a requirement that the user must meet to ensure compliance with the standard; "Should" indicates a recommendation or what it is advised but not required to do; and "may" indicates a possibility or what is permitted.  The notes accompanying the articles do not include prescriptions or recommendations. They serve to separate from the text explanations or information that is not properly part of the norm.  The notes at the bottom of the figures and tables are part of these and may be written as prescriptions.  The annexes are qualified as normative (mandatory) or informative (optional) to specify its application.
