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

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.

By developing quality standards and marks we have become a reliable companion to the pellet industry. DINplus certification is trusted by sellers and manufacturers of wood pellets not only in Europe, but wherever high-quality wood pellets are purchased.

Our aim is to test and certify product quality at all stages of the process chain. To implement this holistic approach, we will assist you with extensive services, like the certification of transport and storage logistic for the wood pellet and fuel industry.

This means that we check, among other things, the steps from the raw material control at the incoming gate, the production with internal quality assurance as well, up to the outgoing goods and the delivery to the end-users.

Furthermore, TÜV Rheinland conducts also testing and certification of pellet boilers etc. TÜV Rheinland thus presents an unique network of experts in the sector of wood pellets worldwide.
