Does NIST prescribe the fixture calibration interval?

No. NIST generally does not prescribe set recalibration intervals. Use your application requirements, stability evidence and approved measurement assurance process to set the due list.

Where do records and fixture handling go?

Enter their labor in setup and record time when it is excluded from verification. Count each task once.

Can all fixture checks use one average time?

Only when the scope is comparable. Separate complex fixtures from simple checks if the average hides a different skill or equipment requirement.

What does a load above 100% mean?

The estimated labor exceeds the net staff hours entered for the period. Add capacity or adjust the schedule without extending required intervals casually.

Fixture Calibration Load Calculator

Estimate labor to complete the fixture verification due list. Enter task times, setup and records, extra investigations and net available metrology hours.

What this calculator does

Build the fixture verification labor requirement and compare it with the metrology hours available for the due list.

Formula used

Verification labor = fixtures due × verification hours per fixture
Setup and record labor = fixtures due × setup and record hours per fixture
Total workload = verification labor + setup and record labor + investigation hours
Capacity headroom = available metrology hours − total workload
Metrology load = total workload ÷ available metrology hours × 100

Inputs explained

Fixtures Due for Verification: Fixtures requiring scheduled dimensional verification in this planning period.
Verification Labor per Fixture: Measured verification labor for comparable fixtures from metrology job records.
Setup and Record Labor per Fixture: Handling, setup and traceability records excluded from verification labor.
Additional Investigation Labor: Separate estimated hours for out-of-tolerance investigations and disposition.
Available Metrology Labor: Net staff hours available for this fixture due list in the period.

How to use the result

Best suited to metrology due list Review, fixture verification staffing.
This does not determine calibration intervals or establish measurement traceability. Equipment, stabilization and approval delays may exceed the labor estimate.

Current U.S. benchmarks

The producer price index for plastic resins and materials stands at 280.569 (BLS, Aug 2026), up 6.6% from a year earlier. Quotes priced off last quarter's material cost miss this move.
The U.S. has 14,378 furniture and related products establishments employing about 355,594 workers (Census County Business Patterns, 2023).
