3.5.2.1 Inner vessel. The inner vessel shall show no evidence of material failure when

tested as specified in 4.6.3.1.

3.5.2.2 Complete assembly. The complete converter assembly shall show no evidence of

system leaks except as noted herein when tested as specified in 4.6.3.2.

3.5.3 Filling time. The time required to fill the converter, which shall have been initially at

room temperature, shall be not greater than 6 minutes when tested as specified in 4.6.4.

3.5.4 Buildup time. The time required to attain the buildup pressure of 70 psig (482 kPa)

shall be not greater than 5 minutes when testing as specified in 4.6.5.

3.5.5 Dielectric strength. The leakage current of the converter sensing element shall be not

greater than 1.0 milliampere when measured as specified in 4.6.6.

3.5.6 Insulation resistance. The insulation resistance of the converter sensing element shall

be 10 megohms between each electrode and converter ground and be not less than 20 megohms

between the electrodes when measured as specified in 4.6.7.

3.5.7 Sensing element calibration.

3.5.7.1 Empty converter. The capacitance of the sensing element shall be 123.5 + 2

picofarads (pf) when tested as specified in 4.6.8.1.

3.5.7.2 Filled converter. The capacitance of the sensing element shall be between the

maximum and minimum limits as derived from the following equations when tested as specified

in 4.6.8.2.

Cmax = (2.33 x W) + 124.7

Cmin = (2.25 x W) + 122.3

C = Capacitance in pf

W = Exact weight of the liquid oxygen in pounds at

the test point.

3.5.8 Relief valve test. The relief valve shall operate between 100 and 120 psig (689 and

827 kPa) and shall allow a minimum flow of 80 liters/min (Lpm) (0.080 cubic meters/min.) at

120 psig (827 kPa) through the valve when tested as specified in 4.6.9.

3.5.9 Evaporation loss test.
