Dimensional Calibration Worksheet

Purpose

The technical record for a dimensional calibration under SOP-25: reference gauges and their temperatures, soak times, laboratory temperature, instrument checks (flatness, parallelism, force, zero), readings at each point and position, temperature corrections to 20 degC, errors, uncertainty and checks.

What it covers

• Item details
• Reference standards and equipment
• Environment
• Instrument checks
• Readings
• Uncertainty and decision rule
• Deviations, observations and nonconforming work
• Checks
• Authorisation

How to complete it

1. 1.Record soak start time and laboratory temperature; record the temperature of the reference and the item at the time of measurement.
2. 2.Record instrument checks (anvil flatness fringes, parallelism, measuring force, jaw condition) before the readings.
3. 3.For each point record the reference block(s) / ring, its certified length, the position (jaw tip / root; anvil orientation), two readings and the corrected error.
4. 4.Record the expansion coefficients and the temperature correction applied.

Before you use it

• Replace every square-bracket token, starting with [LABORATORY NAME], [ADDRESS] and [EFFECTIVE DATE]. The full token list is in GD-01 Read Me First.
• Have the content technically reviewed against how your laboratory actually works, then approved by the responsible manager before it becomes a controlled document.
• Update the Word fields after editing so the table of contents and page numbers are correct: select all, then press F9.
• Record the document in your own document register and set its review date.
