Why Independent Sampling Matters for Settlement
A laboratory result is only as reliable as the sample it receives. If the sample does not properly represent the whole lot, settlement may be based on a misleading quality result. Independent sampling or supervision gives the trader greater confidence that the sample is representative, correctly identified and traceable to the material inspected.
Especta's Role in Independent Sampling
Before sampling begins, Especta reviews the material, lot identification, agreed sampling procedure and the conditions under which the sample will be collected. The sampling operation is then carried out or supervised through to the identification, sealing and documented transfer of the resulting samples.
Material and Lot Verification
The material, lot or sub-lot and relevant identification are checked before sampling begins.
Sampling Procedure
The agreed sampling procedure is reviewed against the material, its form of presentation and the available access to the lot.
Tools and Equipment
Sampling tools and equipment are checked for suitability and cleanliness before use to minimise the risk of contamination.
Increment Collection
Manual sampling is carried out or third-party sampling is supervised, with attention to the systematic collection and identification of increments throughout the lot.
Sample Integrity and Traceability
Collected samples are identified and handled so that their connection to the corresponding lot or sub-lot is maintained throughout the operation.
Sealing and Custody
Final samples are identified, labelled, sealed and distributed as required, with relevant custody transfers recorded.
Reporting
Sampling details, relevant observations, inaccessible areas and any deviations from the agreed procedure are documented in the survey report.
