What is ISO 6446 - Rubber bridge bearings specification about? Elastomeric bridge bearings do not have any moving parts, because the rubber itself allows movement in the bridge. ISO 6446  is an International Standard that discusses rubber products for bridge bearings. ISO 6446 specifies requirements for rubber materials used in elastomeric bridge bearings, which may be of the plain-pad or laminated type. ISO 6446 also specifies methods of testing and describes procedures for the preparation of test pieces from finished bearings. Note: ISO 6446  does not contain aspects relating to design properties and quality control of the complete bearing, except where the complete bearing is used as the source of samples and test pieces to determine the properties of the rubber material. Dimensions and tolerances are therefore not included in .
