A wet sponge Holiday tester at 67.5 volts is employed if coating

thickness does not exceed 500 microns.

Note: Wetting agent such as Foto flow is added to water to

aid in finding holidays.

A dry spark tester is used for holiday detection if the coating thickness

exceeds 500 microns. Holiday test voltage shall be 2400 volts +50 volts.

Note: Holiday test voltage shall be 125 volts DC per 25 micrometers of

maximum coating thickness. However, to eliminate the need for

continual adjustment, a maximum voltage of 2400 volts + 50 volts may

be used for the coating thickness range 350 to 750 micrometers. (09-

SAMSS-089)

B7

Functional operation of the holiday detector is checked.

Note: It is checked by making and testing an artificial holiday in the

coating (not more than 1.6 mm diameter). If the detector is working

properly, it will signal the presence of the artificial holiday.

(SAES-H-200 Para 7.2)

coating (with no visible gaps).

The travel rate of the detector's electrode shall not exceed 300 mm/sec

nor shall it be allowed to remain stationary while the power is on.

Para 8.2.6

B10

Holiday detector is grounded directly to the equipment being tested.

Note: The ground connection shall be made by removing a small area of

coating & attaching the ground directly to the bare surface in such a

manner that electrical arcing does not occur. If the equipment itself is

grounded, it is permissible to ground holiday detector directly to the

earth. (SAES-H-200, Para. 7.3)
