To be sure the converter is functioning, a series of bench tests is made. These tests are made using the test stand and the test stand calibration correction cards, shown in figure 11-6 in chapter 11 of this manual.

Figure 12-8.-Converter performance test sheet (Sheet 2 of 2). PERFORMANCE TEST SHEET PREPARATION Preparation of the liquid oxygen converter Performance Test Sheet (fig. 12-8), which is used for the performance test and for the bench test described later, requires entering the appropriate indicated flows and pressures in the spaces provided. The indicated flows and pressures are extracted from the test stand calibration correction cards (fig. 11-6 of chapter 11). The test stand calibration correction cards contain all actual flows and pressures required to test all known models of liquid oxygen converters presently in service. Converting actual flows and pressures to indicated flows and pressures is normally accomplished during calibration of the test stand. Refer to chapter 11 for calibration intervals. The Performance Test Sheet is prepared as shown in figure 12-8. The Performance Test Sheet shown is a sample, but may be reproduced for local use. The following tests require the extraction of appropriate indicated flows and/or pressures from the test stand calibration correction cards (figure 11-6 of chapter 11). Fill and buildup time test .
