EN 15234-3:2012 (E) 3 Foreword This document (EN 15234-3:2012) has been prepared by Technical Committee CEN/TC 335 “Solid biofuels”, the secretariat of which is held by SIS. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by July 2012, and conflicting national standards shall be withdrawn at the latest by July 2012. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association. The European standard series EN 15234, Solid biofuels  Fuel quality assurance are provided as a general requirements and additional product standards. Additional product standards may extend this series over time. EN 15234 consists of the following parts, under the general title Solid biofuels  Fuel quality assurance:  Part 1: General requirements;  Part 2: Wood pellets for non-industrial use;  Part 3: Wood briquettes for non-industrial use;  Part 4: Wood chips for non-industrial use;  Part 5: Firewood for non-industrial use;  Part 6: Non-woody pellets for non-industrial use. Although these product standards may be obtained separately, it should be recognized that they require an understanding of the standards based on and supporting EN 15234-1. It is recommended to obtain and use EN 15234-1 in conjunction with these standards.
NOTE In these product standards, non-industrial use means - use in smaller scale appliances, such as in households, in small commercial and public sector buildings. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and United Kingdom.

EN 15234-3:2012 (E) 4 Introduction The overall aim of this European Standard is to guarantee the wood briquette quality through the whole supply chain, from the origin to the delivery of the solid biofuel and provide adequate confidence that specified quality requirements are fulfilled.
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.

EN 15234-3:2012 (E) 5 1 Scope This European Standard defines the procedures to fulfil the quality requirements (quality control) and describes measures to ensure adequate confidence that the wood briquette specification described in EN 14961-3 is fulfilled (quality assurance). This European Standard covers the production and delivery chain, from purchasing of raw materials to point of delivery to the end-user. This European standard covers only quality assurance for wood briquettes produced from the woody biomasses stated in EN 14961-1:2010, Table 1 and EN 14961-3. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

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
