Foreword
This Document was drafted as per the rules specified in GB/T 1.1-2020 Directives for
Standardization – Part 1.Rules for the Structure and Drafting of Standardizing Documents.
This Document is Part 2 of GB/T 10095 Cylindrical Gears – ISO System of Flank Tolerance
Classification. GB/T 10095 consists of the following parts.
--- Part 1.Definitions and Allowable Values of Deviations Relevant to Corresponding
Flanks of Gear Teeth;
--- Part 2.Definitions and Allowable Values of Double Flank Radial Composite Deviations.
This Document replaced GB/T 10095.2-2008 Cylindrical Gears - System of Accuracy - Part 2.
Definitions and Allowable Values of Deviations Relevant to Radial Composite Deviations and
Runout Information. Compared with GB/T 10095.2-2008, the major technical changes are as
follows, besides the structural adjustments and editorial modifications.
a) Change the scope of application, which contains a sector gear (see Clause 1 of this Edition;
Clause 1 of the 2008 Edition);
b) Change the terms, definitions, and symbols (see Clause 3 of this Edition; Clause 4 and
Clause 5 of the 2008 Edition);
c) Change the system of flank tolerance classification (see Clause 4 of this Edition; Clause
6 of the 2008 Edition);
d) Change the calculation formula of the radial comprehensive tolerance (see Clause 5 of
this Edition; Clause 7 of the 2008 Edition);
e) Delete the radial runout (see Annex B of the 2008 Edition).
This Document equivalently adopted ISO 1328-2.2020 Cylindrical Gears – ISO System of

Cylindrical Gears – ISO System of Flank
Tolerance Classification – Part 2.Definitions and
Allowable Values of Double Flank Radial Composite Deviations
1 Scope
This Document establishes a gear tooth classification system relevant to double flank radial
composite deviations of individual cylindrical involute gears and sector gears. It specifies the
appropriate definitions of gear tooth deviations, the structure of the gear tooth flank
classification system, and the allowable values of the gear tooth deviations. It provides formulae
to calculate tolerances for individual product gears when mated in double flank contact with a
master gear. Tolerance tables are not included.
This Document is applicable to gears with three or more teeth that have reference diameters of
up to 600 mm.
This Document does not provide guidance on gear design nor does it recommend tolerances.
