Purpose

The technical record for a pressure calibration under SOP-23: reference (pressure balance masses and piston temperature, or reference transducer), medium, orientation, datum heights and head correction, leak test, ascending and descending readings, corrections, hysteresis, uncertainty and checks.

What it covers

  • Item details
  • Reference standards and equipment
  • Environment
  • Set-up
  • Readings
  • Uncertainty and decision rule
  • Deviations, observations and nonconforming work
  • Checks
  • Authorisation

How to complete it

  1. 1.Record the medium, mode (gauge / absolute), orientation and the height difference between reference and UUT datums with the sign convention.
  2. 2.For pressure balance use record masses loaded (IDs), piston temperature, float position and ambient conditions per point.
  3. 3.Record the leak test result before readings and the return-to-zero at the end.
  4. 4.Record exercising and tapping practice.

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.
