This document specifies the mechanical and physical properties of nuts, with coarse pitch thread and
fine pitch thread, made of corrosion-resistant stainless steels, when tested at the ambient temperature
range of 10 °C to 35 °C. It specifies property classes in relation to austenitic, martensitic, ferritic and
duplex (austenitic-ferritic) steel grades for nuts.
ISO 3506-6 provides general rules and additional technical information on suitable stainless steels and
their properties.

This document specifies acceptance and periodic reverification tests of CMM performance with
contacting probing systems and is only applicable to CMMs using:
— any type of contacting probing system; and
— spherical or hemispherical stylus tip(s).
NOTE CMM probing performance tests are specified by the maximum permissible errors (MPEs), due to the
impracticality of isolating the performance of the probing system from that of the CMM, even on a small artefact
such as a test sphere.

A transition is an areal feature connecting two adjacent features, for which the intersection is a line. The transition includes portions of the adjacent features. This document defines a number of specification operators for the specification of defined transitions. These specifications all apply to any line in a defined direction in the transition feature. It also defines the specification modifiers and the drawing indications for such transition specifications.

ISO 12302 specifies for plain bearings (except thick-walled half-bearings) those quality characteristics in accordance with ISO 12301 which can be used to regulate and control a production process on the basis of statistical process control (SPC). It covers dimensional variables but does not take account of attributes.

This document specifies the selective assembly of bearings (in accordance with ISO 3548-1).
The bearing diametral clearance is determined by the housing diameter, journal diameter and the
wall thickness of the two half bearings. Typically, these components will have a total tolerance “stack
up” of 50 μm to 60 μm. Current engine development and in particular, the desire for improved engine
refinement, has provided a need to decrease the clearance range due to the tolerance “stack up”. This

ISO 1206 specifies the boundary dimensions and normal class tolerance values for needle roller bearings with machined rings. This document specifies dimensional and geometrical characteristics, and limit deviations from nominal sizes. These specifications apply to complete needle roller bearings and to bearings without inner ring.
