27、ves NOTE It can be supplied in single or multi-component systems. When applied it produces a cohesive film by the process of solvent evaporation, or solvent evaporation and a chemical reaction. 3.2 cold plastics viscous products supplied in two or multi-component forms (at least one main component a
28、nd a hardener system) and free from solvents NOTE The cohesive film is formed after mixing of all components only by a chemical reaction. Following the reaction, the liquid becomes a solid. 3.3 thermoplastics solvent-free marking substance supplied in block, granular or powder forms NOTE It is heate
29、d to a molten state and then applied. It forms a cohesive film by cooling. DIN EN 12802:2011-12 EN 12802:2011 (E) 5 4 Sampling Samples representative of each component of the material shall be taken from storage, or prior to application, in accordance with EN 13459. Smaller representative samples, o
30、f sufficient quantity to carry out all the tests required, shall be taken from the larger samples. For paints and cold plastics approximately 1 l of the basic component shall be taken. In the case of thermoplastic in powder form, sufficient quantity shall be taken in accordance with EN 13459 so that
31、 it can be melted in a metal container and mixed to a homogeneous mass. After cooling and casting into solid sheets or blocks, representative samples of approximately 1 kg of homogeneous solid material shall be taken for testing. 5 Test methods 5.1 General The standard test methods are listed in 5.2
32、 to 5.4.
