Practice B:
This practice describes the procedure for conducting the
boiling 120-h ferric sulfate–50 % sulfuric acid test.
As result you measure the weight loss and calculate a corrosion rate (millimetre per month).
Practice E:
This practice describes the procedure by which the
copper–copper sulfate–16 % sulfuric acid test...
boiled for 15h to 72h (most common is 24h). After this you bend the specimen and look for "cracks" from IGC.
