| Название (рус.): | Лаки и краски. Определение контрастного отношения (непрозрачности) красок светлых тонов при установленном расходе (с использованием черно-белых карт) |
| Название (англ.): | Paints and varnishes; Determination of contrast ratio (opacity) of light coloured paints at a fixed spreading rate (using black and white charts) |
| Описание (англ.): | The method is based on the observation that contrast ratio is an approximately linear function of reciprocal film thickness, over a restricted film thickness range which also corresponds to that used for normal application ofwhite or ligth coloured paints. It is thus possible to interpolare graphically or by computation between results on films of different thickness, with satisfactory accuracy. Because wet film thickness cannot be determined with sufficient accuracy, the method involves determination of dry film mass per unit area and a calculation of the corresponding wet film thickness. |
