Quality Control & Laboratory Testing

Independent sampling and testing coordination

Hench coordinates the agreed quality-control scope, with particular attention to the identity of the goods and the handling of samples. Laboratory analysis is distinguished from the independent witnessing role.

Sample selection and chain of custody

Sampling, labelling, sealing, transfer and receipt are recorded to connect the test sample with the consignment examined. The sampling plan and any limitations should be agreed before collection.

Selecting tests and laboratories

The commodity, required parameters and relevant specifications determine the testing instructions. Confirm the laboratory capabilities and any required accreditation for the particular test.

Evidence for quality disputes

Clear sampling records and laboratory results help explain what was tested and how. The report does not extend a sample result to an entire consignment without an appropriate basis.

How to arrange the survey

1. Send the shipment or incident details, location, timing and contact person.
2. Agree the scope, access, documents and reporting requirements.
3. Arrange attendance and preserve the relevant evidence.
4. The surveyor records observations, photographs and measurements within the agreed scope.
5. Receive the report and discuss any related assessment or follow-up requirements.
