Performance Tests

Introduction

Introduction

This section contains instructions for testing the performance of the 11970 Series Mixers. Performance tests are used to check the mixers at incoming inspection and for periodic evaluation. The tests verify the specifications listed for the mixers in Table 1-1.

Test equipment required for the performance tests is listed in Table 3-1.for the 11970K, Table 3-2.for the 11970A, Table 3-3.for the 11970Q, Table 3-4.for the 11970U, Table 3-5.for the 11970V and Table 3-6.for the 11970W. Test instruments other than those listed may be used provided their performance equals or exceeds the critical specifications listed in Tables 3-1 through 3-6.

Test Record

At the end of each test is a test record, which is used for recording the performance test data. Make copies of these test records and use them as worksheets when doing the tests.
