Our services for the testing and certification of your wood pellets

International standard for wood pellets:

  • DIN EN ISO 17225-2 (A1) - Solid biofuels - Fuel specifications and classes - Part 2: Graded wood pellets
  • Part of the international standard for quality assurance in the wood pellet logistic and wood pellet storages: DIN EN ISO 20023 - Solid biofuels - Safety of solid biofuel pellets

Requirements for wood pellets for DIN plus certification

Our auditing, testing and certification for wood pellets ensures, among other things, high quality levels in the production of wood pellets through a.o. checks of the internal quality controls. We test products in qualified and recognized testing laboratories. Some of the tested properties are:

  • Water content
  • Bulk density
  • Fine fraction
  • Calorific value
  • Mechanical strength
  • Chemical contamination
  • ash content
  • pellet length

In addition, we also require a lower ash content than the international standard specifies and we determine the so-called ash melting temperature. This temperature is important in estimating the tendency to generate slag.

A certificate is awarded if the result of the evaluation is positive. It is valid for five years, subject to annual controls and in case of deviations unannounced further audits and tests. It can then be extended by five years at a time.

Do you want to know more about our wood pellet testing and certification services? We have compiled the most frequently asked questions for you below.

Show all Hide all

1. What requirements must be met for DINplus certification?

DINplus certification shows that your work is of the highest quality, that you offer consistently high product quality levels, and that you voluntarily submit to annual monitoring. Among other things, we check the goods receipt, storage, preparation and production, as well as the goods issue. In addition, depending on the manufacturer or dealer option, your internal measurements are checked. Furthermore, samples are taken and tested by an independent laboratory approved by us.

If the assessment by DIN CERTCO is successful, you will receive a five-year certificate.

2. What advantages does DINplus certification offer manufacturers, retailers and consumers?

We are the first certification body which developed an international certification for wood pellets already in 2002. By developing quality standards, we have already been a reliable companion of the pellet industry for many years and have earned the trust of manufacturers, traders and consumers. Furthermore, the DINplus certification is mentioned in the I. German Federal Immission Control Ordinance, which underlines the professional acceptance of this certification. We are the first certification body to receive accreditation in this field through an independent review.

All of our partners have been reviewed and recognized by us for their areas of expertise and have independent accreditations, among other things. Therefore, you can rely on our decades of experience and competence. Thus, manufacturers and traders with the DINplus certificate show that you work with confidence and consistently deliver quality that meets consumer expectations.

With DIN CERTCO you have one contact, one application and the same requirement for each country.

3. What do I need to know about packaging?

Wood pellets can be delivered packed or unpacked. Please proceed to our checklist to find out what information must be included on the packaging or accompanying documents.

4. What points must sellers observe?

Fuel sellers and wood pellet suppliers frequently sell their products under their own name without specifying the original pellet producer. Such wood pellets can naturally be marked DINplus as well. To do so, you as the seller need a sub-license, which you can request from our experts in writing. You need the approval of the manufacturer to do so.

If the wood pellet manufacturer already has a DINplus certificate, you can request a certificate via that manufacturer, which will then be issued in the name of the seller or supplier. This certificate depends on the manufacturer's certification in all its aspects.

5. How do I know which wood pellets meet DINplus requirements?

Every successfully certified manufacturer of DINplus wood pellets receives a certificate from us that customers can ask to see at any time. The wood pellet packaging also features the DINplus quality mark with the corresponding registration number. If the pellets are delivered without packaging, the mark with the registration number is shown on the delivery notes.

You can also check our database for certified manufacturers and sellers; it is updated every day. If you still have doubts, feel free to contact us as we strictly follow up fraud cases and mark misuses.

6. Do DINplus pellets comply with normative specification in other countries?

The product certification DINplus for wood pellets based on the requirements of the DIN EN ISO 17225-2. Therefore, DINplus certified wood pellets comply in their characteristics with internal standardized requirements for wood pellets. The German version (DIN) of the standard EN ISO 17225-2 comply in all requirements with other comparable national version of the standard (e.g. NF, UNI or BS). This is guarantee because of the agreed ratification for standards from the different countries, which follow the ratification agreement.
