BS EN 15443:2011

What is BS EN 15443 - Methods for the preparation of the laboratory sample of Solid recovered fuels about?

BS EN 15443 specifies methods for reducing combined samples to laboratory samples and laboratory samples to sub-samples and general analysis samples.

The methods described in BS EN 15443 may be used for sample preparation, for example, when the samples are to be tested for bulk density, biomass determination, durability, particle size distribution, moisture content, ash content, ash melting behaviour, calorific value, chemical composition, and impurities.

Note: The methods are not intended to be applied to the very large samples required for the testing of bridging properties.

Who is BS EN 15443 - Methods for the preparation of the laboratory sample of Solid recovered fuels for?

BS EN 15443 on methods for the preparation of the laboratory sample of Solid recovered fuels is useful for:

• Solid fuels industry
• Producers and traders of solid recovered fuels
• Testing laboratories
• Regulators and controllers of solid recovered fuels
• Quality control authorities
• Buyers of solid recovered fuels

Why should you use BS EN 15443 - Methods for the preparation of the laboratory sample of Solid recovered fuels?

Solid recovered fuels (SRF's) are a major source of renewable energy. European Standards are needed for production, trade and use of solid recovered fuels. For sampling and sample preparation of solid recovered fuels the following European Standards can be used:

• EN 15442, Solid recovered fuels — Methods for sampling
• EN 15443, Solid recovered fuels — Methods for the preparation of the laboratory sample

These European Standards can be used by producers and traders of solid recovered fuels. They are also useful for buyers of solid recovered fuels, regulators, controllers and laboratories.

The main purpose of sample preparation as specified in BS EN 15443 is that a sample is reduced to one or more test portions that are in general smaller than the original sample. The main principle for sample preparation is that the composition of the sample as taken on site shall not be changed during each step of the sample preparation and that possible requirements of the analysis methods to be performed are obeyed.

BS EN 15443 establishes the links between the essential elements of a testing program.

The sample preparation technique adopted depends on a combination of different characteristics of the material and circumstances encountered at the sampling location. The determining factors are:

• The type of solid recovered fuel
• The physical behaviour of the specific solid recovered fuel
• The (expected) degree of heterogeneity (e.g. monostreams, mixed fuels, blended fuels)
