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
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.
