This document specifies a method for the determination of the surface abrasion resistance of anodic oxidation coatings produced by sulfuric acid anodizing of aluminium and its alloys. It is mainly intended for the evaluation of external architectural coatings. It is a production control method that relies to a large extent on operator experience and instruction.

This document specifies a test method using electromotive force test apparatus for assessing the chemical resistance of anodic oxidation coatings on aluminium and its alloys.

This document specifies the procedure for the determination of coating strength, and hence of cohesive strength in a tubular coating tensile test.
The test is intended to determine the tensile coating strength parallel to the spray layers (normal to the spray direction) and to identify differences in particle bond quality.
The tubular coating tensile test is suitable for sprayed coatings deposited using metallic materials (not carbides and ceramics).
The tubular coating tensile test is not su...view more

This document specifies a test method to measure the friction coefficient of chemical conversion coating sheet products and coiled products. This document is applicable to measure or compare the friction properties of hot-dip galvanized, lubricated and resin coated steel sheet, when tested under the same conditions.

This document specifies a gravimetric method for determining the mass per unit area(surface density) of anodic oxidation coatings on aluminium and its alloys. Themethod is applicable to all oxidation coatings formed by anodizing aluminium andits alloys, either cast or wrought, and is suitable for most aluminium alloys,except those in which the mass fraction of copper is greater than 6 %.

This document specifies the acid pickling of aluminium and aluminium alloys free from hexavalent chromium.

This document describes the types of paint and paint system commonly used for corrosion protection of steel structures. It also gives guidelines for the selection of paint systems available for different environments (see ISO 12944-2) except for corrosivity category CX and category Im4 as defined in ISO 12944-2 and different surface preparation grades (see ISO 12944-4), and the durability grade to be expected (see ISO 12944-1).

This European Standard describes a test method to evaluate the performance of photocatalytic materials in water purification by measuring phenol degradation. This test method is applicable to photocatalytic materials in form of powders (suspensions in water, slurries) under UV irradiation. The photocatalytic performance of the tested material is assessed by the observed rate of phenol degradation at specified experimental conditions as determined by HPLC.
