This part of the EN 13523 series specifies two methods for determining the numerical evaluation of the adhesion of strippable films which have previously been applied to an organic coating on a metallic substrate.

Samples can be tested irrespective of whether the strippable film has been applied in the laboratory or on the production line.

NOTE Method 1 is preferred for films with adhesive and method 2 for films without adhesive.

This document specifies requirements for the protection of iron and steel surfaces against corrosion by applying thermal-sprayed metallic coatings of zinc, aluminium or their alloys.

In this document, requirements for the planning of the corrosion protection system and for the constructive design of the component to be protected are specified, where thermal spraying is intended to be the process for the deposition of the metallic corrosion protection.

Some field-related basic terms are defined and instructions for corrosion behaviour of the zinc and aluminium materials under different environment conditions are provided.

Characteristic properties of the coating, e.g. coating thickness, minimum adhesive strength and surface appearance, are specified and test procedures for thermal-sprayed corrosion protection coatings of zinc, aluminium or their alloys are determined.

This document is valid for applying thermal-sprayed zinc and aluminium protection coatings against corrosion in the temperature range between −50 °C to +200 °C, taking into consideration the service conditions of any sealants used. Heat-resistant protective coatings of aluminium are covered by ISO 17834 and are not in the scope of this document.

Other corrosion protection processes, e.g. hot-dip galvanizing (galvanic coating), sherardizing, electroplating or selection and deposition of organic coatings/paints are not in the scope of this document.

Requirements for the manufacturing of thermal-sprayed coatings are specified in ISO 2063-2.

This document specifies a method for using phase sensitive eddy current instruments for nondestructive

measurements of the thickness of non-magnetic metallic coatings on metallic and nonmetallic

basis materials such as:

1. zinc, cadmium, copper, tin or chromium on steel;

2. Copper or silver on composite materials.

The phase sensitive method can be applied without thickness errors to smaller surface areas and to

stronger surface curvatures than the amplitude sensitive eddy current method specified in ISO 2360,

and is less affected by the magnetic properties of the basis material. However, the phase sensitive

method is more affected by the electrical properties of the coating materials.

In this document the term “coating” is used for materials such as, for example, paints and varnishes,

electroplated coatings, enamel coatings, plastic coatings, claddings and powder coatings.

This method is particularly applicable to measurements of the thickness of metallic coatings. These

coatings can be non-magnetic metallic coatings on non-conductive, conductive or magnetic base

materials, but also magnetic coatings on non-conductive or conductive base materials.

When measuring metallic coatings on metallic basis material, the product of conductivity and

permeability (σ, ) of one of the materials should be at least a factor of 2 times the product of

conductivity and permeability for the other material. Non-ferromagnetic materials have a relative

permeability of 1.

The method specifies the gravimetric procedure for determining the non-volatile-matter content as a percentage by mass of the majority of thermally cured coil coatings and subsequently for determining the theoretical spreading rate. The method is not suitable for pure epoxy coil coatings.
