29、 specified temperature. The test panel is evaluated for any uniform or local change such as blistering or corrosion (e.g. red rust, white rust). 5 Apparatus and materials 5.1 Purified absorbent cotton-wool, single layer, of rectangular shape of about 250 mm 650 mm and weighing (22,5 2,5) g. 5.2 Heat
30、 resistant and thermally sealable waterproof plastics bag and the relevant sealing equipment. The plastics bag can be made of polyethylene, for example, and should be at least 0,22 mm thick. 5.3 Specific solution.
