Strauss Test

Strauss Test

Strauss Test

(OP)
Does anyone know the key differences,if any, between ASTM A262 Practise E and ISO 3651 Method 2A. Both are classed as Strauss tests and utilise CuSO4 and H2SO4 in the test solution but I am not sure if the concentrations are the same or if the immersion temperatures are the same.

RE: Strauss Test

While they may not be exactly identical the results are identical.
There was ongoing work to harmonize the two, but I don't know if that actually happened.

I managed to find the information I required which is as follows: -

ISO 3651-2A
Sensitized @ 700C for 30 mins.
20 Hours in boiling Copper Sulphate solution - (100g CuSO4/100mls H2SO4/700mls Water) - Made up to 1000mls with distiller Water
Examine @ x10 after bending through >90 degrees 1T.

ASTM A262-E
Sensitized @ 675C for 60 mins.
24 Hours in boiling Copper Sulphate solution - (100g CuSO4/100mls H2SO4 - Made up to 1000mls with distiller Water)
Examine @ x20 after bending through 180 degrees 1T.
