25、ageBS EN ISO 28121:2017ISO 2812-1:2017(E)ForewordISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member bo
26、dy interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrot
27、echnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of IS
28、O documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held res

The effects of the ex
41、posures are assessed in accordance with agreed criteria.5 ApparatusThe usual laboratory apparatus and, in particular, the following.5.1 Vessel, made of inert material, capable of holding the test liquid and test panels.5.2 Heating cabinet, with artificial ventilation, for carrying out the test at hi
42、gher temperatures (up to 40 C to within 3 C).WARNING To protect against explosion or fire, products containing volatile flammable liquids should be handled with care. 6 Test liquidsOne or more test liquids, as agreed between interested parties, shall be used. Examples of test liquids are given in An
43、nex A.7 SamplingTake a representative sample of the coating material to be tested, in accordance with ISO 15528.Pretest each sample in accordance with ISO 1513 and prepare it for further testing.8 Test pieces8.1 Shape and material8.1.1 PanelsUnless otherwise agreed, use test panels conforming to the
44、 requirements of ISO 1514, with dimensions of approximately 150 mm 100 mm and a thickness of 0,7 mm to 1,0 mm.8.1.2 RodsThe rod shall be made of steel. One end of a rod shall be rounded, with a radius approximately equal to the radius of the rod.NOTE 1 Rods with a length of 150 mm and a diameter of
45、15 mm are suitable.NOTE 2 Rods are used to eliminate edge effects.8.2 Preparation and coating8.2.1 Test panelsPrepare each test panel as described in ISO 1514 and then coat it by the specified application method with the product or system under test.
