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. SIST EN 15234-5:2012

The objective of this European Standard is to serve as a tool to enable the efficient trading of firewood. Thereby: 1) the end-user can find firewood that corresponds to its needs; 2) the producer/supplier can produce firewood with defined and consistent properties and describe firewood to the customers. Quality assurance measures should establish confidence in firewood through systems that are simple to operate and which do not cause undue bureaucracy. Firewood is specified according to EN 14961-5, Solid biofuels  Fuel specifications and classes  Part 5: Firewood for non-industrial use. SIST EN 15234-5:2012

This European standard covers only quality assurance for firewood produced from the woody biomasses stated in EN 14961-1:2010, Table 1 and EN 14961-5. 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 1 MJ/kg equals 0,277 8 kWh/kg (1 kWh/kg equals 1 MWh/t and 1 MWh/t is 3,6 MJ/kg). 1 g/cm3 equals 1 kg/dm3. 5 Quality assurance and quality control measures 5.1 General Quality assurance and control aim to provide confidence that a stable quality is continually achieved in accordance with the customer requirements. 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, system for traceability, 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. Quality assurance on the other hand, is about reviewing the products and processes, primarily through data provided from the quality control records and using this data. a) to provide confidence that products are produced within the required specification and processes are operated as they should be, and
b) to assure that over a longer term either consistency is being maintained (stability in process results) or that quality improvements are making the intended impact.
5.2 Traceability Firewood for non-industrial use shall be specified with EN 14961-5. The origin and source of solid biofuel is specified by Table 1 in EN 14961-1:2010. There are three parts in the supply chain, illustrated in Figure 1.
1) Designation symbols are used in combination with a number to specify property levels (see for example Table 1, EN 14961-5:2011). SIST EN 15234-5:2012

Figure 1 — Simplified example of a firewood supply chain All operators in the supply chain are responsible for the traceability of the origin and source of the material delivered by them. The first operator is responsible for the documents being prepared the first time. The documents shall be available and provided on justified request throughout the entire supply chain according to EN 15234-1. 5.3 Production requirements The methodology described below for quality assurance and quality control of the production shall be used, but shall be adjusted for the production requirements of the specific firewood production chain in question.
There are six consecutive steps that have to be followed by every stakeholder in the supply chain. The steps are described below. For examples of documentation, see informative Annex A. Step 1: Define fuel requirements for the final product (see 5.4) Step 2: Document the steps in the raw material supply, production and distribution processes (see 5.5, Figures 2 or 3) Step 3: Identify quality influencing factors including company performance (see 5.5, Figures 2 or 3) Step 4: Define Critical Control Points for compliance with the fuel specification (see 5.5, Figures 2 or 3) Step 5: Select appropriate measures to assure the quality of t
