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 ISO 6446.
Who is ISO 6446 - Rubber bridge bearings specification for?
ISO 6446 on rubber bridge bearings specification is useful for:
- The rubber industry
- The chemical Industry
- The construction Industry
- Rubber products manufacturers and suppliers
- Rubber product design engineers / innovation teams
- Quality control/testing personnel
- Civil / construction engineers
- Project managers / contractors
- Relevant local authorities
Why should you use ISO 6446 - Rubber bridge bearings specification?
ISO 6446 provides you with a material specification for rubbers used in elastomeric bridge bearings. ISO 6446 enables you to select and specify the options most appropriate to your particular needs.
The requirements of this specification may be divided into two general categories, namely basic
and optional. The basic requirements are those relating to choice of rubber type, overall hardness range, specification of shear modulus or nominal hardness, ozone resistance and source, and preparation of test pieces.
The ability to form a strong adhesion bond is an essential requirement of a rubber used in a laminated bearing. Tests relating to tear strength and resistance to creep are optional and may be added to the specification as appropriate.
ISO 6446 guidelines contribute towards the safety of motorists on bridges.
