Certification I Accreditation

Accreditation and certification are recognized proof of expertise and competence at the Fraunhofer IWES

Fraunhofer IWES aims to meet the requirements of its customers at the highest scientific level. Thanks to its quality, occupational health and safety, and environmental management standards, the institute is both process-oriented and cost-efficient. Furthermore, it is firmly aligned to the needs of both its customers and employees.


Our quality, occupational health and safety, and environmental management system is certified in accordance with ISO 9001, ISO 45001, and ISO 14001.


Our accredited laboratory with the laboratory areas of rotor blade, material laboratory, and field measurements is accredited by Deutsche Akkreditierungsstelle (German National Accreditation Body – DAkkS) in accordance with ISO/IEC 17025 with a flexible scope of accreditation per Category III* and Category I**.
This provides our accredited laboratory areas with objective and internationally recognized proof of their competence.

With the flexible scope, we are able to offer a wide range of tests in the following test areas:

  • Experimental structural testing of rotor blades*
  • Determination of physical properties of fiber-reinforced plastics and composite materials using mechanical and thermal tests**
  • Measurement of mechanical loads on wind turbines and power performance measurements of wind turbines*

* Category III: In this area, the laboratory is permitted, without being required to obtain prior approval from DAkkS, to use the testing methods listed on the certificate with different issue dates of the standards.

** Category I: This next-highest category allows the laboratory – without prior approval from DAkkS – to select standardized or equivalent test methods freely within the defined test area.

IECRE approval

Our accredited laboratory has been approved for the testing of rotor blades as per IEC 61400-23 by the IECRE committee.
The IECRE System (IEC System for Certification to Standards Relating to Equipment for Use in Renewable Energy Applications) offers an internationally valid certification system for products and services in the renewable energy sector. With this, we also satisfy the very highest safety requirements at the same time.
