Alcance
This document specifies procedures for assessing the fracture strength of a protective paint coating of any thickness on a steel substrate of thickness not less than 3 mm. The procedures given in document are based on methods used with different types of pull-off test equipment. The results obtained using such different types of equipment are not comparable.This document is only applicable if a fracture strength value is specified, together with the type of test equipment and the manufacturer of the equipment. Usually, this information is included in contract documentation.This document also specifies suitable equipment and defines inspection areas, sampling plans and acceptance/rejection criteria.It does not give any values of the fracture strength of different protective paint coatings.
