which make the operation processes transparent and should lead to a rapid tracking and solving of problems. aspects of a product certification are combined with those of a system certification. The European Pellet Council (EPC).BACKGROUND AND GOAL The goal of the ENplus certification system for wood pellets is to secure the supply of wood pellets for heating and CHP up to 1 MW output power in residential. commercial and public buildings with a clearly defined and constant quality. as well as the class EN-B. operational procedures and documentation are defined. . The certification system contains the following essential points:     Requirements for wood pellet production and quality assurance Requirements for the product (EN 14961-2) Requirements for labelling. With the classes ENplus-A1 and ENplus-A2. Requirements for technical facilities. three wood pellet qualities are defined that are based on the specifications of the European standard EN 14961-2. The European Biomass Association (AEBIOM) is the owner of the licence rights of the ENplus System. As a result. organised within AEBIOM. To guarantee that a constant level of high quality wood pellets is being delivered. the production as well as logistics and delivery procedures are controlled. logistics and intermediate storage Requirements for the delivery to end customers Specifications for internal quality management guarantee that the product requirements are maintained. These specifications are based on the standards ISO 9001 and EN 15234-2. is responsible for the management and further development of the certification system and the transfer of licence rights to a National Licenser that will organise the introduction of ENplus in their respective countries or geographic areas.

The National Licenser has to choose an accredited certification body for the conformity evaluation of the national ENplus implementation according to ISO 9001 and this handbook. All authorised certification bodies are listed on the official web site of ENplus: www.eu.enplus-pellets. The system support organisation evaluates the conformity of the pellet producer or trader with the ENplus handbook provisions based on the ENplus application and the surveillance inspection report from a listed inspection body. A listed certification body must be accredited according to ISO/IEC 17065 with a member of the European Co-Operation for accreditation (EA). Group Certification The National Licenser may choose a group certification model where he operates as the system support organisation. System Support Organisation A system support organisation is a National Licenser who decides to organise the national ENplus certification as a group certification. The certification body evaluates the conformity of the pellet producer or trader with the ENplus handbook provisions based on their ENplus application and the surveillance inspection report from a listed inspection body. Listed Inspection and Testing Bodies Listed inspection bodies have to be accredited according to EN ISO 17020. The pellet producer or trader will not be issued with a license from the EPC or the National Licenser until they receive approval from a listed certification body or the system support organisation respectively that the produce or trader conform to all the conditions in the ENplus handbook.

Certified Pellet Trader A pellet trader is a company that buys and/or produces pellets and sells them to other traders or consumers. Certified Pellet Producer A pellet producer is a company that produces pellets from woody biomass at one or more production sites. Sub-license Contractor Certified traders may grant a trader who is not certified and has no physical contact (no storage and no delivery vehicle) with the pellets the right to use the certification seal of the certified trader by concluding a sub-licence contract. A copy of the sub-licence contract must be submitted to the responsible National Licenser or the EPC. subsidiary companies. He has to apply with the EPC or National Licenser being responsible for the area where the companies headquarter is situated.g.299) from traders (301 999). Only inspection and testing bodies that are listed on the official web site of ENplus are accepted within the ENplus system. Pellet producers may apply for an ENplus producer certificate with the EPC or the National Licenser being responsible for the area where the companies headquarter is situated. Certified pellet producers are allowed to sell ENplus labelled pellets in bulk to pellet traders and ENplus labelled bagged pellets to everybody.g. The individual selling points may be owned or operated by different legal entities (e. A pellet trader may apply for an ENplus certificate if he sells and delivers bulk pellets – with his own equipment or via a service provider – or if he bags pellets and sells them. The ENplus ID has to be used on declaration labels and delivery documents. In that case. subsidiary companies. respectively.

ENplus also deviates from standard EN 14961-1.3 Stem wood 1..1 Chemically untreated from the wood used wood a) processing industry a) Demolition wood is excluded. In that case as well as for the introduction of innovative additives. which is intentionally introduced into the pellet production – or is added after production – to improve the quality of fuel. The amount of additives in production must be limited to 1. the amount of post-production additives (e.1 Whole trees without roots 1.8 w-%. which does not classify as chemically treated wood. The only exception to this is wood which was externally treated with wood preservatives against insect attack (e.2. must origin from processed or unaltered farming and foresting products.1. coating oils) must be limited to 0. in that the use of chemically treated wood is not allowed.1 Chemically untreated residues from the wood processing industry ENplus-A2 1.

the ID number of the certified company gets blacklisted and will never get assigned to any certified company again. the EPC / National Licenser informs the certification body / system support organisation who will then send the certification document with the identification number and the validity period of the certificate to the applicant. the applicant and the EPC / National Licenser are informed by submission of the conformity report (see Annex 3 and 4). The former licence holder can re-apply for certification and licence after a period of one year. the applicant has to choose a listed inspection body and a certification body / system support organisation in charge for his country. Wood pellets from other locations of the certified company can still be marketed as certified goods.1 Issuing of the Certificate A pellet producer or pellet trader has to apply for a licence with either the EPC or the National Licenser. The certified company will be listed in a register with all other certified companies. In the case of group certification. After the successful approval of his application he will be issued a new ID number. The certification period starts with the issuing of the certificate. the National Licenser / EPC has the right to suspend the licence to use the ENplus trademark for a limited period or terminate the licence contract and request the certification body to revoke the certificate. 3. If an application is made with a National Licenser. which is published on the websites of the National Licenser and the EPC. the licence can be suspended for the location where the non-conformities were assessed until such time that they have been corrected. When proof of the down payment of the licence fee has been received and the signed contract has been returned to the EPC / National Licenser. the certification period is the same for all members of the group.Handbook for the Certification of Wood Pellets for Heating Purposes 3 CERTIFICATE 3. If the certified company has several locations. The EPC / National Licenser will send the applicant the licence contract and a request for payment of the licence fee.2 Validity of the Certificate The certificate is valid for one certification period. Certified producers and certified traders will receive a new certificate at the beginning of each certification period. such as the initial inspection report (including the results of the laboratory tests) in case of pellet producers. When violations of the ENplus certification programme occur or if the certification body states that a certified company is non-conforming. If an application is made with the EPC. the applicant has to choose a listed certification body and a listed inspection body. If the application is approved. 13 . One certification period lasts three years. The certification body or the system support organisation approves the conformance of the application with the ENplus certification guidelines based on the information in the application form and any additional documents submitted. If the licence and the certificate are revoked.

In addition. client master data.2) The objection is only permissible when the applicant or certified company proves that the affected decision violates his/her own rights.4) Ordering of more frequent inspections in the scope of internal controls Suspension and cancellation of the certificate / the licence (see 3.6 Sub-licensing Sub-licensing is a means to increase the number of selling points of ENplus pellets without additional costs for the certified trader. The contract is only valid in the country where the certified trader is located. he may act as a sub-licensed trader of a certified trader. Any person who is directly affected by the objection decision will not participate in the decision making process. A written decision on the objection will be made within two weeks by an objection committee to be set up by the National Licenser/ EPC.5 Objection Proceedings Applicants and certified companies can file a written objection to the National Licenser and the EPC against the following decisions:      Refusal of the requested certification Ordering of new monitoring inspections Ordering of extraordinary inspections (see 3. e. 3.g. The basic principle is that the physical handling of the pellets is performed in total by the certified trader. It is mandatory that the non-certified trader has no own technical equipment such as stores and delivery vehicles. inspection body. 3.Handbook for the Certification of Wood Pellets for Heating Purposes 3.g.4 Regular and Extraordinary Inspections Pellet producers have to undergo one mandatory annual audit. extraordinary audits can be carried out upon demand by the certification body / system support organisation or the EPC / National Licenser. Additionally. 3. delivery vehicles) to the EPC / National Licenser. Traders are audited within the first year of certification and then at least once every certification period. He will be allowed to sell ENplus pellets in bulk if a sub-licence contract with the certified trader grants them the right to use the ENplus ID of the certified trader.3 Reporting Obligations The certified company has to immediately report any changes relating to the information given in the original application form (e. if significant numbers of complaints are received. 14 . In that case. The sublicence contract has to be submitted to the national organisation / EPC by the certified trader. quality manager. extraordinary audits can be carried out if quality concerns are raised.

the height of the identification number may not be any smaller than ten per cent of the seal’s height. Certified companies who manufacture or trade certified and noncertified goods have to avoid the impression that the complete production and trade quantities are certified. Through a system of unique identification numbers (ENplus IDs). Use of the logo without the identification number is only possible with the permission of the National Licenser / EPC. 5 TRACEABILITY AND TRANSPARENCY A tracking system serves as a self-control and quality assurance aid to find out where the failures in the supply chain occurred and to identify which batches are out of specification. The numbers 001 to 299 will be assigned to producers. The seal must be displayed in one of the colour variations or in monochrome specified in Annex 1. The certification seal may only appear on delivery notes and invoices if they are issued exclusively for ENplus certified pellets. Country codes are specified by ISO 3166-1-alpha-2. 15 . The ENplus ID of the certified company is an essential component of the certification seal and must be displayed below the ENplus logo. the numbers 301 to 999 to traders.Handbook for the Certification of Wood Pellets for Heating Purposes 4 CERTIFICATION SEAL Every certified producer and trader has a unique certification seal for each pellet quality class it produces or sells. They have to use their trader ENplus ID for bulk deliveries to end customers.1 ENplus ID Each ENplus ID has five characters that specify whether the certified company is a trader or a producer and which country he comes from. each delivery should be able to be traced from the end customer through the entire logistics chain back to the producer. Therefore. The three digits after the country code provide the number of the certified company in his country. and consumer direct sales. Companies who have been certified with DEPI in 2010 may use the numerical codes proposed in the German ENplus handbook 2010 until the end of 2014. an imprint of the sellers’ ENplus ID on the delivery documentation is mandatory for each delivery of ENplus pellets for both. The ENplus logo has to be a minimum height of 15 mm. The first two digits indicate the country where the pellet producer or trader is located. but a minimum height of 1. Certified Pellet producers who deliver loose pellets to end customers also need a trader certificate. The seal has to be exclusively used in direct connection with the certified product. 5. Furthermore. When the certificate is issued.5 mm (Arial font size of 10). the certified company is granted the right to use the certification seal for the corresponding quality class to label its products and for advertising purposes.. business to business sales.

Handbook for the Certification of Wood Pellets for Heating Purposes The whole supply chain can be identified by combining multiple ENplus IDs into an ID chain. amount of pellets and the licence plate number of the delivery vehicle must be documented. Certified producers have to take a minimum of 1. The same applies for each certified trader who operates an own storage. 5. Usually. quality class. or display only his ENplus-ID.g. The samples have to be archived for at least 9 months under proper conditions. The samples have to be sealed. 5.3 Trade of Bagged Pellets Certified wood pellets in bags should be labelled in the language of the country where the pellets are to be marketed. Additionally. The sample bags must have a consecutive registration number. each ID is to be separated by a blank space. In case of loading at a producer’s site. The samples may be stored at the producers’ site. The label has to cover the following specifications:    “Wood pellets” with the corresponding quality class Mass (in kg or metric ton) Diameter (6 mm or 8 mm) 16 . but in case of complaints he must be able to trace the origin of the pellets from his internal documentation. certified traders have to take a minimum of 500 g reference sample from each loading of a delivery vehicle. The registration number should be stated in the delivery checklist. that of the producer and those of all the traders involved in the supply chain.2 Reference Samples The analysis of a reference samples offer a solid basis for the decision on quality related complaints from end customers or of disagreements on pellet quality between producers and trades. but this could be complex or even impossible if he buys or stores pellets from different certified producers. The date of sampling and the quality class of the pellets must be documented. customers should be informed of where their particular delivery of pellets originates from. However. common samples for the producer and the trader are sufficient. The date.5 kg reference sample per each day of delivery and loading point. A T 0 1 2 D E 3 4 4 Since traceability and transparency are basic features of ENplus. He may add the place of loading instead. a certified trader should use the ID chain. Reference samples have to be taken after the last sieving. The following example of an ID chain indicates that pellets were produced by the Austrian producer 012 and delivered by the German trader 344. from the moving material or from the silo of the delivery vehicle. the certified trader must have access to the stored samples. e.

5 g pellets are weighed and treated in the Ligno-Tester for 60 seconds at 70 mbar. Special care is necessary for equipment maintenance and service requirements (e. A2-5 Moisture Content (M) The determination of the moisture content should be done according to EN 14774-2. After excess material has been removed by striking a straight edge along the top and larger cavities have been filled.1 g). Subsequently. The remaining wood pellets will be weighed and the mechanical durability will be determined using the following formula: DU = mA *100 mE DU mE mA mechanical durability (%) mass of the pre-sieved wood pellets before mass of the sieved wood pellets after A2-4 Bulk Density (BD) The determination of the bulk density is done according to EN 15103. Wood pellets are poured from a height of 200 to 300 mm into a measuring cylinder with a volume of five litres until the cylinder is full and a debris cone has formed. After the mass has been determined within 15 seconds after removing it from the drying chamber (weighing as hot). The procedures described by the equipment manufacturers must be observed.g. the cylinder will be dropped three times from a height of approximately 150 mm on a hard surface in order to consolidate the wood pellets. The sample will then be dried in a drying chamber (oven) at (105 ± 2) °C until constant mass has been achieved. a Ligno-Tester may be used. the mass of the full container is determined.Handbook for the Certification of Wood Pellets for Heating Purposes Alternatively. First. The bulk density (BD) will be calculated using the following formula: BD = (m2 − m1 ) V BD m1 m2 V bulk density mass of the empty container mass of the full container net volume of the measuring cylinder Note: household measuring beakers or plastic buckets are not considered as suitable equipment. the moisture content will be calculated using the following formula:  ( m − m3 )  M = 2 * 100  (m2 − m1 )  M m1 m2 moisture content as received (w-%) mass of the empty drying pan mass of the drying pan and sample before drying 34 . the mass of an empty drying dish will be determined (accuracy: 0. regular check of accuracy of pressure gauge and frequent change of dust filter). the dish will be filled with at least 300 grams of wood pellets and reweighed. 100 g ± 0. Subsequently.

Care must be taken that all fine particles are separated but no new fine material is formed due to intensive sieving. The sample should be hand sieved using a 3. faster methods may be used e. In that case. The sieved fine material is weighed. A2-6 Amount Fine Material (F) The determination of the content of fine material should follow EN 15210-1. the testing procedures described by the equipment manufacturers must be observed including sample preparation requirements. Online measurement of moisture content is recommended only for process control but does not substitute sampling and determination of moisture as described above.15 mm sieve according to ISO 3310-2.Handbook for the Certification of Wood Pellets for Heating Purposes m3 mass of the drying pan and sample after drying Alternatively. infrared balances or a humimeter. The fine material amount (F) will be calculated as follows: F= mA *100 mE mE mA mass of the sample before sieving mass of the sieved particles 35 .g.
