If a test sample passes, the drop height is increased by one unit. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
The test sample rests on a base plate over an opening of specified diameter. An “impactor” sits on top of the test sample with a nose of specified radius in contact with the center of the test sample. For optimum results using the staircase method, a minimum of 30 test samples are necessary. The most common method to analyze this data is called the “Bruceton Staircase” method.
