Section 39.571. Protectors

(a) Approval of protectors. Protectors of each type to be used shall be submitted to the Board for approval. Protectors which do not meet the specifications and tests set forth in this subchapter shall not be used and the furnishing of substandard materials by manufacturers shall be sufficient cause for the revocation of the certificate of approval covering such protectors.

(b) Design and construction of frames. Protectors shall be substantially constructed and so designed as to permit the replacing of lenses or windows when necessary without the use of tools of special make or design.

(c) Test for corrosion. The effects of corrosion on the metal of the frame and shields shall be judged by immersing a pair of goggles in a boiling aqueous 10% (by weight) solution of sodium chloride for a period of 15 minutes. The frames upon being removed from this solution shall be immediately immersed in a 10% (by weight) aqueous solution of sodium chloride at room temperature. They shall then be removed from this solution and, without wiping off the adhering solution, allowed to dry for 24 hours. The metal parts shall then be rinsed in lukewarm water and allowed to dry. On inspection the surface shall be smooth. Goggles padded with suitable material so that the face is protected from metal contact need not withstand the corrosion test.
