European standard EN 13706 for pultruded profiles

European Standard EN 13706 applies solely to pultruded profiles for “structural purposes”, which according to the standard are defined as “where the load-bearing characteristic is the major criterion of design and where the product is part of a load-bearing system”.

The standard specifies the minimum requirements for the quality, tolerances, strength, stiffness and surface of structural profiles.

The standard basically divides pultruded structural profiles into two classes:

E23 – having the most stringent requirements to quality
E17 – having more lenient requirements to quality

Fiberline structural profiles meet or exceed the requirements of class E23.

The standard broadly consists of three parts:

EN 13706-1: Specifying the designation/labelling/marking of structural profiles with regard to selection of materials, selection of reinforcement, surface treatment, etc.

EN 13706-2: Indicating testing methods and tolerances for pultruded structural profiles. Guidelines for quality and quality assurance are also given.

EN 13706-3: Indicating minimum values for the technical properties of structural profiles in relation to the standard’s two classes.
