Resistance to external blows. Round-the-clock method.

Test methods

A sample (pipe) is subjected to impacts from a hammer with a set weight and shape, from a known height. The result is expressed as TIR (number of failures divided by the number of blows, expressed as a percentage as if the entire batch had been tested).
