1. SCOPE

1.1 This standard prescribes methods for reducing combined samples (or increments) to laboratory samples and laboratory samples to sub-samples and general analysis samples and is applicable to solid biofuels.

1.2 The methods prescribed in this standard are to be used for sample preparation, when the samples are to be tested for calorific value, moisture content, ash content, bulk density, durability, particle size distribution, ash melting behavior, chemical composition, and impurities.
