Document-controlled GPS magnitude comparison
Documented General Geometrical Deviation Comparator
Compare a measured geometrical-deviation magnitude with a documented limit for the same characteristic,zone definition,datum system and modifiers. Legacy ISO 2768-2 tables are not reproduced or presented as current.
Documented magnitude comparison
Implemented comparison—not a tolerance generator
utilization=100x/t
x≤t → numerically at or below entered limit
x>t → numerically above entered limit
Values are normalized to millimetres with1mm=1000µm exactly. The comparison has meaning only when x and t are the same nonnegative magnitude characteristic under the same specification and evaluation definitions.
NEEDS_LICENSED_SOURCE: the former page reproduced H/K/L tolerance tables and automatically generated limits. The old standard is withdrawn,and the public ISO records do not expose the normative table text or authorize treating those values as an ISO 22081 lookup. The tables were removed rather than copied forward or relabelled.
ISO 2768-2 withdrawal and current framework
Official records: withdrawn ISO2768-2:1989 and current ISO22081:2021. A legacy drawing remains a controlled contractual record;do not silently rewrite it without engineering/configuration authority.
Related GPS interpretation and decision rules
ISO1101:2017,Edition4,confirmed2022,defines the symbol language and rules for geometrical specification. ISO8015:2011,Edition2,confirmed2021,states fundamental GPS concepts and rules. Neither public abstract supplies the feature-specific limit entered here.
ISO14253-1:2017,Edition3,current at stage90.93,addresses conformity/nonconformity decision rules and measurement uncertainty. This page deliberately reports only the raw x-versus-t magnitude comparison and does not implement a decision rule.
Public ISO22081 scope boundary
The official abstract says its general geometrical and size specifications apply only to integral features,including features of size;not to derived features or integral lines. Dimensions other than linear or angular sizes are outside its size-specification coverage. Exact applicability still depends on the invoked specification and full licensed text.
Why the former calculator was removed
It presented the withdrawn1989 standard as current,generated limits from closed tables,defaulted to classK/perpendicularity/100mm,and described K as the most common class. Its perpendicularity note said “shorter side of angle” while the code actually selected the table by nominal dimension. It had no measured deviation,measurement method,uncertainty record or conformity boundary. Those errors were removed at their source.
