GENERAL INFORMATIONThe information given below is provided for assistance and clarificationand does not represent requirement(s) to this specification.5.1 Density of the Dry Film See Initial S

28、ample(FLTM BI 154-02) +/- 0.02 kg/L5.2 FILM THICKNESSThe f ilm thickness required in para 3.6.3 is for test purpose onlyand may deviate from the film thickness applied in production.The nominal film thickness is 20 micrometre. The minimum thicknessshall not fall below 10 micrometre.Application of paint in a film thickness more than 20 micrometre maygive the necessity to improve the drying conditi ons. These conditionsmust be determined during a line trial.Drying conditions must also be modified in case IR-drying is used.
