I believe what Ing. Gremmen described is the true spirit of immunity testing - you must tailor the test technique to the characteristics of the test sample. As he noted, however, sometimes you have to modify the method of assessing compliant behavior in order to accomplish the test in a reasonable time period. This is all part of engineering, it is more than just lock-step response to standardized test procedures.
