In this article, we will delve into the details of both standards, exploring their requirements, the differences between them, and why these distinctions are critical for users.
Introduction to Z87 Standards
The Z87 standard is a widely recognized benchmark for safety eyewear in the United States. Established by ANSI, it outlines the requirements for the design, testing, and use of protective eyewear to prevent or minimize injuries to the eyes and face from chemical splashes, flying particles, and other hazards. The standard includes specifications for the frame, lens, and other components of safety glasses, goggles, face shields, and welding helmets. It ensures that safety eyewear can withstand impact from blunt and sharp objects, provides adequate optical clarity, and is comfortable for wearers.
Components of the Z87 Standard
The Z87 standard encompasses several key components, including:
– Impact Resistance: Eyewear must pass a high-velocity test where a 1/4 inch steel ball is dropped from 50 inches, and a high-mass test where a 17.6 ounce steel projectile is dropped from 5 feet onto the lens.
– Optical Clarity: Lenses should not distort vision and must meet specific requirements for astigmatism, power, and prism variation.
– Chemical Resistance: Eyewear prescribed for chemical handling must protect against chemical splashes.
– Frame Requirements: Frames should be designed to retain the lens upon impact and ensure wearer comfort.
Understanding Z87+
Z87+ is an evolution of the Z87 standard, designed to offer enhanced protection, particularly against high-velocity impact. While the Z87 standard requires that eyewear can withstand the impact of a 1/4 inch steel ball dropped from 50 inches (the high-velocity test), the Z87+ standard goes a step further by requiring that the eyewear can also withstand a 1/4 inch steel ball traveling at higher velocities (representing more severe impact conditions). This enhanced requirement makes Z87+ eyewear more suitable for environments where there is a higher risk of high-speed particles or objects striking the eyes.
