The European standard series EN 15234, Solid biofuels Fuel quality assurance ar

16、e 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-in

17、dustrial 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 a

18、n 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

19、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

BS EN 15234-6:2012EN 15234-6:2012 (E) 4 Introduction The overall aim of this European Standard is to guarantee t

21、he non-woody pellet 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 non-woo

22、dy pellets. Thereby: 1) the end-user can find a pellet that corresponds to its needs; 2) the producer/supplier can produce a pellet with defined and consistent properties and describe the pellet to the customers. Quality assurance measures should establish confidence in the pellet through systems th

23、at are simple to operate and do not cause undue bureaucracy. Non-woody pellets are specified according to EN 14961-6, Solid biofuels Fuel specifications and classes Part 6: Non woody pellets for non-industrial use. BS EN 15234-6:2012EN 15234-6:2012 (E) 5 1 Scope This European Standard defines the pr

24、ocedures to fulfil the quality requirements (quality control) and describes measures to ensure adequate confidence that the non-woody pellet specification described in EN 14961-6 is fulfilled (quality assurance). This European Standard covers production and delivery chain, from purchasing of raw mat

25、erials to point of delivery to the end-user. This European standard covers only quality assurance for non-woody pellets produced from the non-woody biomasses stated in EN 14961-1:2010, Table 1 and EN 14961-6. 2 Normative references The following referenced documents are indispensable for the applica

26、tion 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.

29、 biofuel made from pulverised (e.g. ground) biomass with or without additives usually with a cylindrical form diameter 25 mm, random length and typically 3,15 mm to 40 mm with broken ends, obtain by mechanical compression NOTE The raw material for non-woody pellets can be herbaceous biomass, fruit b

30、iomass, or biomass blends and mixtures. They are usually manufactured in a die with a total moisture content usually less than 15 % of their mass. 3.2 additive material which improves the quality of the fuel (e.g. combustion properties), reduces emissions or makes production more efficient 3.3 chemi

35、. 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 hi

36、gh quality but a steady and continually achieved quality in accordance with the customers 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 companys performance, such as documentation (product dec

37、laration, 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 doc

38、uments 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. 1) Designation symbols are used in combination with a number to specify property

39、levels (see for example Table 1. EN 14961-6:2012). 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. BS EN 15234-6:2012EN 15234-6:2012 (E) 7 Quality control is fundamentally about controllin

40、g 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 re

41、viewing 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

42、 consistency is being maintained (stability in process results) or that quality improvements are making the intended impact. 5.2 Traceability Non-woody pellets for non-industrial use shall be specified with EN 14961-6. The origin and source of solid biofuel is specified by Table 1 in EN 14961-1:2010

43、. The main three parts of the supply chain is illustrated in Figure 1. Figure 1 An example for the description of a non-woody 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 r

44、esponsible 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. BS EN 15234-6:2012EN 15234-6:2012 (E) 8 5.3 Production requirements The methodology described below for quality a

45、ssurance and quality control of the production shall be used, but shall be adjusted for the production requirements of the specific pellets 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.

46、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 production and distribution processes (see 5.5, Figures 2 and 3) Step 3: Identify quality influencing factors including company performance (see

47、5.5, Figures 2 and 3) Step 4: Define Critical Control Points for compliance with the fuel specification (see 5.5 Figures 2 and 3) Step 5: Select appropriate measures to assure the quality of the product (see 5.6) Step 6: Establish routines of separate handling of nonconforming raw materials and soli
