22、Manufacturers Association F.8.3 Test Sequence The sequence of tests to be performed on a new sample is as follows: Note: Each detergent or sanitizer chemical shall be tested and evaluated independently in the test sequence given below. Test 1: Chemical compatibility test if applicable. Chemicals to

23、be used shall be defined by the end use application (see F.8.1.1). Test 2: High-pressure power wash test shall be performed on same sample after test 1 is completed.
