In Australia, workplace eye protection is governed by stringent standards to ensure that safety glasses offer the necessary protection against potential hazards. Understanding these standards and the testing process helps consumers and businesses make informed decisions when purchasing safety eyewear. This post will guide you through how safety glasses are tested and certified in Australia, referencing the Australian Standards.

Safety glasses in Australia must comply with the Australian Standard AS/NZS 1337.1, which provides the guidelines for non-prescription eye and face protectors. This standard ensures that all safety glasses meet required safety criteria, including optical clarity, impact resistance, and coverage.

1. Testing Procedures for Safety Glasses

• Impact Resistance: Safety glasses are subjected to impact tests where small steel balls or similar objects are fired at the lenses at high speeds. This tests the lenses' ability to withstand impacts without shattering or dislodging.
• Optical Clarity: Optical tests check for any distortion or imperfections in the lenses that could impair the wearer's vision. These tests ensure that the lenses do not alter or distort the wearer's sight.
• Coverage and Fit: Tests are conducted to ensure that the glasses provide adequate coverage around the eyes and fit securely. This is crucial for preventing particles or debris from bypassing the glasses.
• Durability and Aging: Safety glasses are also tested for durability under various conditions, such as exposure to UV light, extreme temperatures, and corrosive substances, to simulate aging and wear.

2. Certification Process

Once safety glasses have passed all required tests, they can be certified as compliant with AS/NZS 1337.1. Manufacturers must label their products with the standard's mark, indicating their certification status. This mark is a consumer's assurance that the product meets all required safety specifications.
