Analysis is a set of tests carried out on a sample of wood pellets (or other fuel). The main use of analysis is to verify that the wood pellets comply with the supplier's specification. As explained above, analysis does not substitute for specification, because of the impossibility of knowing that the results are not just representative (i.e. typical or average for the load from which the sample was taken), but a worst case.

Check all the parameters match between specification and analysis of wood pellets

You should always check carefully that the set of tests included in the analysis results include all the parameters that you need to know. It is natural, when reading through a set of results, simply to compare those results with the required specification, and not to check whether certain parameters are missing altogether.

Tests on wood pellets should be carried out by accredited laboratory

You should also check that the analysis has been carried out by an independent laboratory accredited to carry out the tests in accordance with the standard methodologies. If the laboratory is not independent and suitably-accredited (for each test), you will have to be more careful to check that the appropriate tests have been carried out properly.
