ISO 14916 – Determination of Tensile Adhesive Strength

ISO 14916  Thermal spraying — Determination of Tensile Adhesive Strength

ISO 14916 specifies the procedure to determine the tensile adhesive strength of thermally sprayed coatings under tension in the direction normal to the surface of the

coating by applying a tensile test.

The test is intended to determine the tensile adhesive strength between the thermally sprayed coating and the substrate material or between the bond and top coat

and /or of the cohesive strength of the related coat of the coating system. In some cases, thermally sprayed coatings might have more than two layers.

This test is sufficient to compare coatings manufactured using same or similar feedstock materials and thermal spray processes with each other.

The tensile adhesive strength test is not intended to provide absolute values for evaluation of the durability of coatings under operational use.

The test is used to assess the influence of substrate preparation, the spraying conditions and the process parameter on the tensile adhesive strength of thermally

sprayed coatings.

It can also be employed in order to monitor the consistency of the manufacturing and spraying processes.

*** A tensile-testing machine in accordance with ISO 7500-1  is required

*** Before conducting ISO 14916 , it is important to read the entire specification. Standards can be obtained from appropriate standard authorities.

***PARSROS  offers several types of grips and fixtures which will enable you to perform a variety of tests

  that are accurate and repeatable.
