ISO 12817 – Open-Hole Compressions Strength of Plastic Composites

ISO 12817 Specifies the test method to determine the open-hole compressive strength of laminated fibre-reinforced plastic composites.

The laminate is intended to be a balanced and symmetrical lay-up or be otherwise homogeneous through the thickness.

It applies to all textile diameter fibre types (carbon, glass, aramids, etc.) and matrices (e.g. thermoset, thermoplastic) that meet its requirements.

ISO 12817 includes three methods:

Method 1 (short specimen with support fixture);

Method 2 (short specimen without support fixture);

Method 3 (long specimen with support fixture as in ASTM D 6484M-09, methods A and B).

*** Before conducting  ISO 12817, it is important to read the entire specification. Standards can be obtained from appropriate standard authorities.
