Define a functional width-tolerance record

Connect measurement conditions to both sides of the assembly window.

Constrained interfaces
Record: Buckle slot, guide, folder, fixture, seam or coverage point
Project detail: ____________________
Confirm: Measure controlled physical parts

Width stage
Record: Before or after finishing, relaxed delivered roll and any conditioning
Project detail: ____________________
Confirm: Name the acceptance stage

Measurement setup
Record: Gauge, contact shape, pressure, orientation and handling of curved tape
Project detail: ____________________
Confirm: Demonstrate operator method

Sampling positions
Record: Roll selection, distance from ends, positions along each roll and reading count
Project detail: ____________________
Confirm: Mark positions on inspection plan

Functional limits
Record: Nominal, minimum for coverage or grip and maximum for passage
Project detail: ____________________
Confirm: Trial boundary samples in assembly

Decision rule
Record: Individual limits, treatment of average, invalid readings and recheck
Project detail: ____________________
Confirm: Apply to recorded spread

Tolerance values and sample frequency are project-defined. Report individual readings and spread; do not use an average to hide an out-of-limit section.
