§ 39.576. Goggle frames.
(a) Metal frames shall be made of a material that is able to withstand sterilization and which does not readily corrode or discolor the skin. Frames shall have a smooth finish. Each frame shall bear some permanent distinctive marking by which the manufacturer, dealer or distributor may be readily identified. This marking does not apply to goggles now in use.
(b) The frames of types 1 and 2 goggles having either adjustable or rigid bridges shall withstand the tests prescribed in this section and § 39.577 (relating to goggle lenses and frames). The frames of protectors having rigid bridges shall also withstand tests prescribed in subsections (c) and (d).
(c) Each frame tested shall have the right lens frame laid flat, with the outer surface of the lens downward, on a firm level support so that the left lens and half the bridge is allowed to project beyond the edge of the support. A spring balance shall be connected to the outermost portion of the frame of the left lens, and a downward force of 223 grams (8 ounces) shall be applied while the right lens frame is rigidly held. After removal of the load no permanent deformation shall be apparent in the frame.
(d) Each frame tested shall have the right lens frame held vertically in one hand and the lower edge of the left lens frame pressed against one of the platforms of an equal-arm balance having a weight of 1.82 kg. (four pounds) on the other platform. The pressure shall be increased until the weight is balanced, whereupon the frame is removed and examined for bending. After removal of the load no permanent deformation shall be apparent in the frame.
