Symbols in test conditions have the following interpretation: |
A – without preliminary preparation |
С - preliminary preparation in damp air |
D - preliminary preparation in the distilled water |
E - preliminary preparation at this temperature |
F - testing after a series of heatings by means of hot damp air |
des - preliminary preparation in the form of drying in the drying camera |
T - testing at this temperature |
