On-Site Calibration at Customer Premises

Purpose

To define how calibrations are planned, performed, recorded and reported at customer premises or other sites outside the Laboratory's permanent facility, so that the requirements of ISO/IEC 17025 for environment, equipment, traceability, competence, records and reporting are met to the same standard as in the laboratory.

Records it generates

Applying this procedure produces the following records, which are the evidence an assessor samples.

• –On-site work record with conditions, equipment, items, customer signature and risk assessment
• –Pre- and post-transport intermediate checks
• –Site survey questionnaires
• –Site kit checklists

What an assessor looks for

The document closes with these points, so you can check your own practice before someone else does.

• –Reviewing FRM-47 for a sampled on-site job: conditions recorded, within limits, pre-use and transport checks done.
• –Checking the on-site uncertainty budget differs appropriately from the laboratory budget.
• –Confirming the certificate states the site as the location and that the schedule covers site calibration for that activity.
• –Possibly witnessing an on-site job during assessment.

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.
• Delete the assessment readiness notes if you do not want them in your controlled version; they are guidance for you, not requirements.
