BS ISO 26602:2009

Fine ceramics (advanced ceramics, advanced technical ceramics). Silicon nitride materials for rolling bearing balls. | Status: Superseded, Withdrawn

1 Scope This International Standard specifies the requirements for preprocessed silicon nitride materials for rolling bearing balls. This International Standard provides a classification defining physical and mechanical properties of silicon nitride preprocessed bearing ball materials. The materials are classified in three categories by the specification of characteristics and microstructures. Methods for sample preparation and observation of microstructures are provided in Annex A.

NOTE The silicon nitride product means the sintered body of which the main component is silicon nitride material.
