6 Test/Calibration reports/certificates will normally be posted but, by arrangement, may be collected from the laboratory to which the samples were Italic font indicates a test not frequently performed, infrequent test (performed less than once per year). The test may require longer time to perform if equipment needs tobe calibrated prior to performing the test and/or staff need to be re-trained and audited before performing the test. Additional samples may be required for re-training/auditingAggregatesshall be calibrated before use. HOKLAS certificates areissued only if the relevant calibration requirments are Test Directory (Date issued : )P.
