Which materials a reviewer needs
Supply the complete report, appendices, questions posed and available laboratory test reports. Sampling, packaging and sample identification information matters. Individual pages may support discussion of the task, but assessment completeness will be limited.
Sampling and methods used
Checking establishes whether the examined object is clear, how it relates to the question and whether the work programme is sufficiently described. It considers whether selected indicators meet the task and whether method limitations are reflected when presenting the result.
The result and its interpretation
Checking may address units, comparability of results, selection of requirements for comparison and the transition from an individual sample to a broader finding. Every criticism should identify a document passage, explain the problem and its effect on the answer.
When new measurements are needed
Documents allow assessment of the data and reasoning presented. If a disputed question requires checking the sample itself or obtaining a missing indicator, a new examination is discussed. A review does not generate absent laboratory results or guarantee a predetermined dispute outcome.
