Material Testing & Compliance for Sustainable Development

Material testing, material cards, material data sheets and compliance – milestones for new sustainable developments

We are surrounded by materials at all times and everywhere. From sports equipment to aircraft, materials play a significant role. Structural strength, durability or haptics – properties that define product safety and quality perception. In the automotive industry specifically, we can look back on many years of experience at ARRK Engineering.

As a capable partner, we support the development of components or subsystems from the material perspective; from material selection and static and dynamic material testing, right through to comprehensive identification of characteristics, and specification of CAE material cards used by us or our customers in structural CAE design.
In addition, we help automotive manufacturers and their suppliers to comply with statutory directives in the field of material restrictions and material compliance. We take complete responsibility for compiling material data sheets from all suppliers, evaluating them until approval and creating at the end material balances as the basis for homologation approval by using complex macro-programming.

Besides, we evaluate resource efficiency and/or CO2 impact along a component or vehicle life cycle, from product creation, through use, to recycling by processing high quality Life Cycle Assessments (LCA).

Furthermore, we accompany companies in their sustainability analysis and their way to sustainable innovations.


The expertise in our materials area ranges from support in material selection to the evaluation of the material in the component from a physical, legal and sustainability point of view. To assist product development from all material-related perspectives, we provide established expertise in the following competence areas.


We take over the compliance with legal substance regulations for components or vehicles for our customers with regard to their availability and demonstrability, in order to ultimately enable a type approval.
Moreover we offer the OEMs and their suppliers a long standing expertise in the evaluation and creation of material data sheets (MDS) for the development phase, in consideration of the actual materials and chemicals legal standards and requirements (REACh, EU end of life vehicles directive ELV, CQC, etc).
The long-term experiences in a professional elaboration of databases and an established knowledge of the common platforms (IMDS, CAMDS, SCIP…) enables us to handle projects independently and completely in terms of material conformity, from pre-development to homologation.
  • Supplier management
  • Evaluation and creation of material data sheets
  • Preparation of material balances
  • Report writing for REACh declaration §33 and obtaining homologation release
  • Filling of the SCIP and CQC databases
  • Tracking of legislative changes and identification of affected pollutants in the vehicle
  • Change management for material restriction cases
  • Creation of customer-specific programming and automation


To obtain sufficient information on existing material and evaluate its suitability for use in the development of a component, numerous tests are required. We execute these tests in accordance with international test standards based on ISO 17025 processes.
