1 Scope This European Standard specifies a method for the production of specimens suitable for testing vitreous and porcelain enamel coatings. The standard specifies 2 different specimens:  specimens taken from production article, and
 specially produced specimens.
NOTE Only the specially produced specimens can be used when the loss in mass per unit area of the enamel coating is to be determined quantitatively as specimens cut from enamelled articles can reduce the accuracy of the test method. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 14430, Vitreous and porcelain enamels — High voltage test 3 Designation Specimens prepared in accordance with this European Standard shall have the following designation: Specimen EN 15206-(substrate) where a steel substrate shall be designated by A, a cast iron substrate by B and an aluminium substrate by C. EXAMPLE The designation of a specimen prepared in accordance with EN 15206 by using a steel substrate is: Specimen EN 15206-A 4 Specimens from production articles 4.1 Requirements for the used articles The specimens shall be taken from a production article that was produced with the normal production parameters.
Reworked articles shall not be used as specimens. 4.2 Shape and dimension requirements The specimens shall be circular or square with a diameter or side length of 105 mm ± 5 mm. The specimens shall be taken only from the flat areas of enamelled articles. NOTE For enamelled aluminium specimens on which only the adherence is to be determined using the procedure given in ISO 13805 [1], other shapes may be used.

The width of the zone from which the enamel shall be removed shall be the width of the cutting tool plus 2 mm on each side. NOTE Grinding machines operating with corundum or diamond stones are suitable for removing the enamel. 5 Specially prod
