T/GZZB 001-2020 Fogproof medical isolation goggles (protective glasses)
Basic Information
Scope
Scope: This standard specifies the technical requirements, production environment, test methods, inspection rules, marking, packaging, transportation, and storage requirements for anti-fog medical isolation eye shields (goggles). This standard applies to protective shields made of polymer materials, consisting of foam strips and fixing devices. They are provided non-sterile, for single use, and are used in medical institutions to provide protection during examinations and treatments, preventing the splashing or spattering of bodily fluids and blood. Main technical contents: - The visible light transmittance should be no less than 85%. - The visible light haze should be no more than 2%. - The temperature resistance performance should not show obvious discoloration, bubbling, deformation, or cracking. - The drop resistance performance should not show obvious damage that affects use when dropped freely from a height. - The droplet protection performance: If no color spots appear on the test paper within the center of the lens, the lens is considered qualified. - The refractive index difference should be within +0.05 to -0.07D. - The elastic modulus of the frame material should be 1.5–15 MPa. - The elongation at break of the frame material should be ≥200%. - The anti-fog performance: The eye shield should not fog up within 10 hours, allowing clear visibility of the head model's facial identification symbols.
