Meaning
Procedural standards for the extraction and preservation of material specimens ensure that test results remain valid during a quality dispute.
Witness Attendance
All parties involved in the transaction must be present to observe the selection of the samples from the production lot. A joint sampling protocol requires the signatures of both the buyer and the seller on the security seals. This presence prevents later claims that the samples were tampered with or were not representative of the batch.
Security Measure
Tamper evident bags and unique identification codes are used to track each specimen from the factory floor to the laboratory. If the seals are broken before the official testing begins, the joint sampling protocol is considered violated and the results are inadmissible. Chain of custody documents must be maintained to record every person who handled the material.
Dispute Resolution
Neutral third party inspectors often act as the primary handlers to ensure objectivity during the collection process. When the laboratory report is issued, the pre-agreed joint sampling protocol provides the legal basis for accepting the findings as final. This agreement prevents the need for re-testing and speeds up the settlement of quality claims.
Such protocols are frequently mandated by insurance companies before they will cover transit or manufacturing risks.
