Interferences
1 Unusually high levels of iron (above 10 mg/l) will cause low results for total
hardness.
2 The pH required in the test is closely controlled by a buffer mixture
included in the tablet formulation. However, to avoid exceeding the buffer
capacity strongly acid or alkaline samples should be adjusted to within the
pH range 4 to 10, prior to the start of the test.
