7、ACTERISTICS. The following characteristics differ from those listed in the latest issue of A-A-59326. 3.1 Accessories. The coupling shall be supplied with pull rings and gasket. 3.2 Cam arms. The 6-inch 150 rated female cam-locking end shall have 4 cam-arms. 3.3 Hydrostatic test pressure. The 1-inch
8、 through 4-inch couplings shall withstand a hydrostatic test pressure of 300 pounds per square inch gage (psig). The 6-inch, 75 psi rated couplings shall withstand a hydrostatic test pressure of 150 psig. The 6-inch, 150 psi rated couplings shall withstand a hydrostatic test pressure of 225 psig. 3.
9、4 Working pressure. The -inch through 4-inch couplings shall be rated for 150 pounds per square inch working pressure. The 6-inch couplings shall be rated for 75 psi or 150 psi working pressure as appropriate. 4. NOTES 4.1 Part Identification Number (PIN). The following PIN procedure is for governme
