Scope of standard

1.1 This specification covers the establishment of the basic quality, physical/mechanical property, and test requirements for silicon nitride rollers Classes I, II, and III to be used for cylindrical roller bearings. 1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values from the two systems may result in nonconformance with the specification.
