ISO 1518-1-2011 pdf download.Paints and varnishes – Determination of scratch resistance 一 Part 1: Constant-loading method. This part of ISO 1518 specifies a test method for determining under defined conditions the resistance of a single coating o a multi-coat system of paint, varnish or related product to penetration by scratching with a scratch stylus loaded with a specified load. Penetration of the stylus is to the substrate, except in the case of a multi-coat system, in which case the stylus can penetrate either to the substrate or to an intermediate coat. The method specified can be carried out a) either as a pass/fail” test, by testing with a single specified load applied to the stylus to assess compliance with a particular specification; b) or by applying increasing loads to the stylus to determine the minimum load at which the coating is penetrated. 2 Normative references The following referenced documents are indispensable foi the application of this document.

ISO 16474-2-2013 pdf free.Paints and varnishes – Methods of exposure to laboratory light sources – Part 2: Xenon-arc lamps. This part of Iso 16474 specifies methods for exposing specimens to xenon-arc light in the presence of moisture to reproduce the weathering effects that occur when materials are exposed in actual end-use environments to daylight or to daylight filtered through window glass. The specimens are exposed to filtered xenon-arc light under controlled conditions (temperature, humidity and/or wetting). Various types of xenon-arc lamps and various filter combinations may be used to meet all the requirements for testing different materials. Specimen preparation and evaluation of the results are covered in other International Standards for specific materials. General guidance is given in ISO 16474-1.

ISO 15184-2020 pdf free.Paints and varnishes – Determination of film hardness by pencil test. This document specifies a method for determining the film hardness by pushing pencils of known hardness over the film. The test can be performed on a single coating of a paint, varnish or related product, or on the upper layer of a multi-coat system. This rapid test has not been found to be useful in comparing the pencil hardness of different coatings. It is more useful in providing relative ratings for a series of coated panels exhibiting significant differences In pencil hardness. The method is applicable only to smooth surfaces. 2 Normative references The following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document.

ISO 4628-1-2016 pdf free.Paints and varnishes – Evaluation of degradation of coatings一 Designation of quantity and size of defects, and of intensity of uniform changes in appearance一 Part 1: General introduction and designation system. This part of ISO 4628 defines a system for designating the quantity and size of defects and the intensity of changes in appearance of coatings and outlines the general principles of the system used throughout ISO 4628. This system is intended to be used, in particular, for defects caused by ageing and weathering. and for uniform changes, for example yellowing. The other parts of ISO 4628 provide pictorial standards or other means for evaluating particular types of defect. As far as possible, already existing evaluation schemes have been used as the basis. This part of ISO 4628 is also used for assessing defects not covered by the other parts of ISO 4628. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

ISO 4624-2016 pdf free.Paints and varnishes一Pull-off test for adhesion. ISO 4624 specifies three methods (i.e. one dolly or two dollies on a painted panel and two dollies, one as painted substrate) for determining the adhesion by carrying out a pull-off test on a single coating or a multi-coat system of paint, varnish or related product. These test methods have been found useful in comparing the adhesion behaviour of different coatings. It is most useful in providing relative ratings for a series of coated panels exhibiting significant differences in adhesion. The test may be applied using a wide range of substrates. Different procedures are given according to whether the substrate is deformable, for example thin metal, plastics and wood, or rigid, for example thick concrete and metal plates. To avoid distortion of the substrate during the tensile test, it is common to use a sandwich construction. For example, for special purposes, the coating may be applied directly to the face of a test dolly. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

ISO 4628-7-2016 pdf free.Paints and varnishes – Evaluation of degradation of coatings一 Designation of quantity and size of defects, and of intensity of uniform changes in appearance一 Part 7: Assessment of degree of chalking by velvet method. This part of Iso 4628 specifies a method suitable, in particular, for rating the degree of chalking on white or coloured exterior coatings and coating systems on rough surfaces (i.e. those having a roughness greater than segment 4 of the reference comparator G as described in ISO 8503-1). The test method specified can also be used for the assessment of the degree of chalking of coatings and coating systems on smooth surfaces, but the method specified in ISO 4628-6:2011 is preferable for this purpose. The test method is applicable to coatings and coating systems on mineral substrates, e.g. fibre cement, brick, concrete, and renderings, independent of the structure of the surface. The method can be used quite effectively by experienced operators and is recommended for laboratory use as well as for on- site evaluation. NOTE I When a reference to this test method is included In specifications, the test conditions (I.e. weathering method and substrate) have to be agreed between the interested parties….

ISO 22970-2019 pdf free.Paints and varnishes – Test method for evaluation of adhesion of elastic adhesives on coatings by peel test, peel strength test and tensile lap-shear strength test with additional stress by condensation test or cataplasm storage. This document specifies three methods for testing the peel adhesion, peel strength and tensile lap- shear strength in order to evaluate the adhesive bond as well as the type, location and structure of failures of elastic adhesives on coatings. These methods are used, for example, for testing the assembly with respect to the bond of panes or built-on parts, such as plastic covers, spoilers, instrument panel covers, headlights, with coatings for automobile construction. The two methods of climatic exposure of specimens described herein are the condensation test and cataplasm storage. This document does not specify requirements for adhesives and coatings. NOTE The peel strength test (method B) for rigid car body construction adhesives is described In ISO 8510-2. The tensile lap-shear strength test (method C) for rigid car body construction adhesives is described in EN 1465. Testing of rigid car body construction adhesives is generally conducted on small joint thicknesses. i.e. ci mm. The following documents are referred to in the text…
