EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of EN ISO 16276-1 testing. EN ISO 16276-1 specifies procedures for assessing the breaking strength of a protective paint coating of any thickness on a steel substrate not less than 10 mm thick. The procedures given in this part of ISO 16276 are based on methods used with different types of tensile test equipment. The results obtained using such different types of equipment are incomparable.
This part of EN ISO 16276 also specifies appropriate equipment and defines inspection areas, sampling plans and acceptance/rejection criteria. It does not give any value on the breaking strength of different protective paint coatings.
The main purpose of this part of EN ISO 16276 is to complement the ISO 12944 series regarding site assessment and acceptance criteria of adhesion/cohesion of a coating.
This part of EN ISO 16276 introduces the term "breaking strength", which includes both adhesion and cohesion. Adhesion and cohesion are defined in ISO 4618, while the ISO 12944 series uses the term "adhesion" only.
Break strength testing is normally destructive and therefore requires repair work, the extent of which will depend on the specification and durability required by the protective paint coating. The purpose of this part of EN ISO 16276 is to provide uniformity in the evaluation of the breaking strength of a coating and to establish acceptance/rejection criteria for protective paint coatings. The method uses test equipment based on the pull principle.
For a protective paint system with a given breaking strength, a set of test values will be obtained from different types of equipment. Specifying the test equipment giving the highest test values for a given breaking strength does not necessarily imply higher durability for that protective paint system. Also, high test values for a given breaking strength do not necessarily mean high durability for that protective paint system.
