English to Romanian Tech/Engineering Materials (Plastics, Ceramics, etc.)

Tear-off strength values and characteristics shall be evaluated against the reference areas or against the specifications of the paint manufacturer. In any case, however, an adhesive tensile strength of more than 8 MPa must be achieved. Adhesive fractures on the substrate are not permitted. On layers where a tensile test is not possible due to the specific properties (for example silicone aluminium) this can be omitted.
