Which ISO 14405-1 edition is current?

ISO lists ISO 14405-1:2025,Edition 3,as published and ISO 14405-1:2016 as withdrawn on 6 August 2025.

Does this page generate H7 or shaft-class deviations?

No. ISO 286-2 contains the tables;this page requires lower and upper limits copied from a controlled source.

Does within the entered limits prove conformity?

No. The result must match the specified size characteristic/operator and measurement definition,and conformity requires the applicable uncertainty decision rule.

Document-controlled GPS size comparison

Documented Linear-Size Limit Comparator

Compare one measured size result with documented LLS and ULS for the same size characteristic,operator and feature. No ISO tolerance table or operator is generated.

x<LLS → below; LLS≤x≤ULS → within entered limits; x>ULS → above

Values normalize to millimetres using1mm=1000µm and1in=25.4mm exactly. These differences are general arithmetic,not formulas prescribed by ISO 14405-1.

NEEDS_LICENSED_SOURCE: the former page embedded H7/H8/H6/g6/h6/k6/p6/js7/f7/e8 range values and operator/modifier claims. ISO 286-2:2010 is the table standard and has Corrigendum1:2013;ISO 14405-1 changed in2025. Exact rows,boundaries,symbols and defaults must be checked in licensed controlled texts before any generator is restored.

ISO 14405-1 lifecycle

ISO 14405-1:2025Edition3,published6August2025. The public scope covers cylinders,spheres and two parallel opposite planes and states that it establishes the default and defines a special specification operator.

ISO 14405-1:2016Edition2,withdrawn6August2025 and revised by the2025 edition. Its broader public abstract must not be copied forward as current requirements.

ISO 286 and decision boundary

ISO286-1:2010,Edition2,confirmed2026,defines the code system and concepts;Corrigendum1:2013 applies. ISO286-2:2010,Edition2,under systematic review,contains tables of classes and limit deviations;Corrigendum1:2013 applies. A single shaft or hole class does not by itself define a fit—both mating features and their basic sizes are required.

ISO8015:2011 supplies GPS fundamentals,not a numeric fit table. Measurement uncertainty and the governing conformity decision rule remain outside this raw comparator.

Why the former controls were removed

The page presented a preselected g6 shaft class as a “fit”,allowed incompatible combinations such as a p6 shaft with a hole-oriented maximum-inscribed selection,generated limits from an unlicensed table,omitted400–500mm despite accepting500mm,and used defaults,presets,weak parsing and local history. Those choices were removed rather than updated by guesswork.
