Overview

EN 15234-3:2012 - Solid biofuels: Fuel quality assurance - Part 3: Wood briquettes for non‑industrial use (CEN) defines quality assurance and quality control procedures for the entire wood‑briquette supply chain. It sets out practical measures to ensure that wood briquettes comply with the fuel specification in EN 14961-3 and that buyers and end‑users can rely on consistent product characteristics from raw material purchase through production, delivery and storage. The standard applies only to briquettes made from the woody biomasses listed in EN 14961‑1 (Table 1) and is aimed at non‑industrial applications (households, small commercial and public buildings).

Key topics and requirements

• Scope and applicability
  • Quality assurance framework for wood briquettes produced from specified woody biomass.
  • Coverage: purchasing, production, packing, distribution and delivery to end‑user.
• Quality system structure
  • Six mandatory steps for every stakeholder: define fuel requirements; document processes; identify quality‑influencing factors; define Critical Control Points (CCPs); select assurance measures; manage nonconforming materials.
• Traceability
  • Full traceability of origin and source of raw material through the supply chain; documentation provided on request.
• Production and process controls
  • Identification and monitoring of CCPs (examples: raw material receipt, post‑drying, mould/press temperature, storage).
  • Control of equipment, drying, particle size, additives and contamination (stones, metals, plastics).
• Inspection and handling
  • Incoming raw material inspection, delivery declarations, sustainability documentation (e.g., PEFC/FSC).
  • Storage, packaging and transport requirements to prevent moisture uptake and contamination; separate storage for different quality classes.
• Product declaration and labelling
  • Requirements for declaring fuel quality to customers, with informative examples provided in annexes.

Practical applications and users

Who uses EN 15234-3:2012:

• Producers and manufacturers of wood briquettes - to implement QA/QC systems and demonstrate compliance with EN 14961‑3.
• Suppliers, wholesalers and retailers - to document product quality, labelling and traceability for customers.
• Testing laboratories and certification bodies - to verify compliance and support product declarations.
• End‑users and building operators - to select briquettes that match appliance and performance needs. Practical benefits include improved trading efficiency, reduced complaints, consistent combustion performance, and clear contractual terms.

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
