(b) Using a double balanced bridge or a four-terminal milliohmmeter, measure the resistance between selected points of the signal ground network. Where lower frequency ground networks exist, measure the resistance between those points on the network where equipment interconnections are made. Measurements between equipment cabinets should not exceed 20 milliohms. Measurements between the cabinet and ground or the cabinet and the structure should be no more than five milliohms. (6) A comprehensive survey of the bonding subsystem should include the following items (figure 6-2). (a) Visually check a representative number (5 to 10 percent) of the various types of bonds in use throughout the facility. Welded, brazed, or silver soldered connections should be examined for broken or cracked seams, presence of voids, size of filler deposit length and number of deposits (if discontinuous), and evidence of corrosion.
