Test Records, Reporting, and Qualification of Test Personnel
Records, reporting, and personnel
Test records are the evidence that the work was done correctly. A complete field report identifies the project, sample location, date and time, material and batch, test standard, specimen identification, curing and conditioning history, test age, equipment, results, and the name and certification of the technician. Reports should include individual specimen values as well as averages and should note any deviation from the standard-such as a shortened curing period, a nonstandard specimen size, or a field-made water addition. Without traceability, a result cannot be defended in a dispute.
Reporting traps include stating only an average, omitting the sampling location, failing to identify the test method or its edition, and recording a result without the units or the basis (net versus gross area, dry versus saturated mass). Another common error is assuming that a laboratory report is self-authenticating: qualifications, equipment calibration records, and chain-of-custody documents are part of the record.
Personnel qualification is equally important. The ACI Masonry Field Testing Technician program certifies individuals who demonstrate competence in sampling, consistency and water-content testing, specimen molding, and related field procedures. Certification does not replace the standard; it confirms that the technician knows how to apply it.
Worked example: a report lists a prism strength of 1800 psi but gives no prism dimensions, no h/t correction, and no curing record. That report is incomplete; the value cannot be verified, and the technician should be required to supply the missing data or retest.
