Division 4

Where necessary to ensure valid results, the organisation shall have procedures to ensure that its measuring equipment is:

1. (a)

   calibrated or verified at specified intervals, or prior to use, against international, national or industrial measurement standards — where no such standards exist, the basis used for calibration or verification shall be recorded;

2. (b)

   adjusted or re-adjusted as necessary;

3. (c)

   identified to enable the calibration status to be determined;

4. (d)

   safeguarded from adjustments that would invalidate the measurement result;

5. (e)

   protected from damage and deterioration during handling, maintenance and storage.
