| x 2572 -2- 9.2.21. Contd. of 205 at a frequency of 50.7 when the milliamperes of capacity current taken by the condenser shall lie between the limits 12.5 and 16.0. (3) If satisfactory as regards (1) and (2), the condenser shall now be finally fitted up in its case. (4) The first part of Test (1) should now be exactly repeated except that the 400 volts should be maintained for five minutes only. The capability of holding a static charge should again be verified in a similar manner. Note:- Corresponding capacity limits in microfarads = .19 to .245. EFC. {E.
