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.

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).
1) Designation symbols are used in combination with a number to specify property levels (see for example Table 1, EN 14961-2:2011). 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 15234-2:2012

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 Wood pellets for non-industrial use shall be specified with EN 14961-2. 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.
Figure 1 — Simplified example of a wood pellet 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. SIST EN 15234-2:2012
