DIN 18202 Ebenheitstoleranz Lookup

Audit actual straightedge gap under caller independently verified DIN 18202 edition/element/span interpolation policy, no invented tolerances, inspection protocol or legal conformity. Caller independently verifies units, applicability and matching conditions; no operational recipe, safety certification, causal efficacy or legal/resource classification is inferred.

Description

A straightedge flatness check depends on span and a matched tolerance specification.

A straightedge flatness check depends on span and a matched tolerance specification.^[1]

Interpolating caller limits does not install the DIN standard or prove that interpolation is appropriate for its edition. Use DIN 18202 Ebenheitstoleranz Lookup to evaluate the supplied inputs under the model explained below.

When to use DIN 18202 Ebenheitstoleranz Lookup

Use DIN 18202 Ebenheitstoleranz Lookup to evaluate the supplied inputs under the model explained below. Establish the units, measurement scope and model assumptions before entering values.

How to use DIN 18202 Ebenheitstoleranz Lookup and understand its results

Establish the units, measurement scope and model assumptions before entering values.
Enter Caller verified straightedge spans mm, Caller verified din flatness limits mm, Observed straightedge span mm, Observed measured gap mm using the field table and validation rules below, then run the tool.
Read Caller interpolated flatness limit mm, Signed measured flatness margin mm; interpret the units, signs, ordering and unknown-value placeholders described below.
Correct reported input errors and rerun. Apply successful results according to their specific meanings and check the assumptions before using them in a decision.

Input field	Meaning	Value type	Requirement
callerVerifiedStraightedgeSpansMm	Caller verified straightedge spans mm	array of number	Required; constraints below
callerVerifiedDinFlatnessLimitsMm	Caller verified din flatness limits mm	array of number	Required; constraints below
observedStraightedgeSpanMm	Observed straightedge span mm	number	Required; constraints below
observedMeasuredGapMm	Observed measured gap mm	number	Required; constraints below

Enter at least two strictly increasing positive straightedge spans in mm and aligned nonnegative independently verified flatness limits in mm, plus positive observed span within the range and nonnegative measured gap in mm. Linearly interpolate the supplied limit and return limit minus gap. Zero margin is equality. The caller must establish the correct edition and whether interpolation is permitted; no DIN table or inspection protocol is installed.

limitMm=linearInterpolate(callerSpans,callerLimits,observedSpan); marginMm=limitMm−measuredGapMm

Use the field order, units and branch conditions described above.

Output field	Meaning	Value type
callerInterpolatedFlatnessLimitMm	Caller interpolated flatness limit mm	number
signedMeasuredFlatnessMarginMm	Signed measured flatness margin mm	number

Limitations and assumptions

Interpolating caller limits does not install the DIN standard or prove that interpolation is appropriate for its edition. Apply the exact scope and assumptions explained above.

All listed fields require explicit values. Unexpected fields, incorrect types, nonfinite numbers and sparse arrays fail validation. Domain-specific bounds, alignments and supported tokens are explained above; extremely large inputs or outputs can also be rejected. Input errors differ from successful false results, empty match lists and unknown-evidence placeholders.
