TITLE: FMVSS INTERPRETATION

TEXT: Thank you for your letter of June 30, 1967, to Mr. Bridwell concerning windshield wiper parts.

We recognize that it may be difficult to obtain reflectance values from all metal components on the windshield wiper assembly which come into the driver's field of view. For this reason, Motor Vehicle Safety Standard No. 107 includes reflectivity requirements for only the wiper arm and blade. As stated in your letter, the reflectivity of these components may be determined by using flat samples of identical material. Reflectivity requirements for the spring, rivets and other hardware items, which are attached to the wiper arm and blade, are not presently specified in Standard No. 107.
