It can be supplied in single or multi-component systems. When applied by brush, roller, spra
26、y or any other appropriate method it produces a cohesive film by the process of solvent evaporation and/or by a chemical process 3.2 thermoplastics a solvent-free marking substance supplied in block, granular or powder forms. It is heated to a molten state and then applied with an appropriate hand o
27、r mechanical applicator. It forms a cohesive film by cooling 3.3 cold plastics a marking substance which is supplied in single or multi-component forms. Depending on the type of system the components are mixed together in various ratios and applied with an appropriate applicator. It forms a cohesive
28、 film only by a chemical process 4 Sampling Samples representative of each component of the material shall be taken from storage in accordance with prENV 13459-1:1999. Smaller representative samples, of sufficient quantity to carry out all the tests required, shall be taken from the larger samples.
29、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 prENV 13459-1:1999 so that it can be melted in a metal container and mixed to a homogeneous mass. After cooling and
30、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 to 5.4. Alternative quantitative analytical test methods may be used providing that: the
31、resulting values are comparable to those obtained using the standard methods; and the repeatability of the alternative methods, determined in accordance with ISO 5725-2:1994, can be shown to be not less than that of the methods given in this standard. 5.2 Paint 5.2.1 Density The density of the paint

43、f the solids content A.1 Principle The volatile constituents of the paint are evaporated at 105 8C. The residual solids are weighed and the solids content calculated. The solids are used as the basic material for further tests. A.2 Apparatus a) Cooling equipment, refrigerator or water bath, with the
44、rmostat at approximately +10 8C; b) erlenmeyer flasks, two flasks made of heat resistant glass with standard ground neck and stopper (45/40) of 250 ml or 300 ml capacity; c) analytical balance, with an accuracy of 0,001 g, with zero point correction; d) warming cupboard, with forced fresh air ventil
45、ation and flame-proof interior capable of being heated to 105 8C2 8C; e) desiccator, with drying agent, e.g. silica gel. A.3 Reagents Thinner consisting of three parts toluene p.a. to one part acetone p.a. by volume. A.4 Procedure A.4.1 Carry out two determinations. A.4.2 Mark the erlenmeyer flasks
46、and stoppers with numbers. Record both the mass of the empty erlenmeyer flask (L) and that of the flask together with the ground stopper (Ls) to the nearest 0,001 g. Place approximately 2 g of the paint, pre-cooled to 10 8C and homogenized, in the flask with a spoon. Tightly seal the flask with the
47、ground stopper and weigh to the nearest 0,001 g (mass Ml). Swirl the flask to distribute the sample evenly over the bottom. NOTEIn the case of paints that are highly viscous or have a tendency to form a skin it is advisable, after weighing the sample, to add a few millilitres of a suitable thinner (
48、the toluene/acetone mixture or the manufacturers recommended thinner) in order to achieve a better distribution of the sample over the bottom of the flask. Remove the stopper, cover the neck of the flask with a filter paper and store for approximately 16 h (overnight) at room temperature to enable t
49、he solvent to evaporate. Place the flask containing the sample in a warming cupboard at a temperature of 105 8C2 8C and store there for at least 6 h or until constant mass is reached. Constant mass is reached when, after the sample has been in the warming cupboard for a further 1,5 h, the mass loss is less than 0,2 % of the initial mass. Cool the flask to room temperature in the desiccator, reseal with the stopper and weigh to the nearest 0,001 g. Use the solid residue remaining in the flask as the basis for determining the binder content
