This Technical Specification describes methods for taking samples of solid biofuels that are transported in lorries, and is applicable to solid biofuels that are either:-fine and regularly-shaped particulate materials, particle sizes up to about 10 mm that can be sampled using a scoop, for example: sawdust, olive stones and wood pellets;-coarse or irregularly-shaped particulate materials, particle sizes up to about 200 mm that can be sampled using a fork or shovel, for example: wood chips and nut shells, forest residue chips, and loose straw.It may be used, for example, when the samples are to be tested for bulk density, durability, particle size distribution, moisture content, ash content, ash melting behaviour, calorific value, chemical composition and impurities. It is not intended for obtaining the very large samples required for the testing of bridging properties. It does not provide any information on how often lorry-loads should be selected for sampling.
