The objective of this European Standard is to serve as a tool to enable the efficient trading of wood briquettes. Thereby: 1) the end-user can find a briquette that corresponds to its needs; 2) the producer/supplier can produce a briquette with defined and consistent properties and describe the briquette to the customers. Quality assurance measures should establish confidence in the briquette through systems that are simple to operate and do not cause undue bureaucracy. Wood briquettes are specified according to EN 14961-3, Solid biofuels  Fuel specifications and classes  Part 3: Wood briquettes for non-industrial use.
NOTE The raw material for wood briquettes is woody biomass in accordance with Table 1 of EN 14961-1:2010. Briquettes are usually manufactured in a die/mould, with total moisture content usually less than 15 % of their mass on wet basis. 3.2 additive material which improves the quality of the fuel (e.g. combustion properties), reduces emissions or makes production more efficient 3.3 chemical treatment treatment with chemicals other than air, water or heat NOTE Examples of chemical treatment are listed in informative Annex C of EN 14961-1:2010. 3.4 impurities material other than the raw material or fuel itself such as soil, stones, metal, plastic, glass SIST EN 15234-3:2012

It means that specified requirements are fulfilled, but it does not necessarily mean a high quality but a steady and continually achieved quality in accordance with the customer´s requirements. The customer is the next operator in the supply chain. Customer requirements include not only the fuel quality, but also the quality of the company’s performance, such as documentation (product declaration, labelling of packaging, etc.), timing and logistics (to provide biofuels in time and to agreed performances criteria). Fuel quality assurance needs to be applied to the entire supply chain. As the supply chains for solid biofuels in the most cases needs to be kept very simple, the same documents are often used for documentation of quality assurance and quality control measures. NOTE When the customer is a supplier, a retailer or end user, the customer requirements are usually written in sales contracts. Quality control is fundamentally about controlling the quality of a product or process to enable the delivery of the product or service within agreed parameters in the most efficient and cost effective way. The consequences of having good quality control will be a cost effective product and process.
1) Designation symbols are used in combination with a number to specify property levels (see for example Table 1, EN 14961-4:2011). For designation of chemical properties chemical symbols like S (sulphur), Cl (chlorine), N (nitrogen) are used and the value is added at the end of the symbol. SIST EN 15234-3:2012
