14 Load Test
14.1 When the locking mechanism or other means used to prevent separation incorporate materials not in compliance with 6.2, the locking mechanism or other means used to prevent separation of the two components shall withstand an axial load of 400 pounds (1775 N) without separating or becoming inoperative, when tested in accordance with 14.2.
14.2 Three samples of the cylinder connection device shall be used. With the two parts connected
together as intended in service, and the cylinder portion rigidly anchored, an axial load of 400 pounds (1775 N) is to be applied to the appliance portion at a rate not in excess of 600 pounds (2700 N) per minute.
15 Endurance Test
15.1 A cylinder connection device and adapter, after being subjected to the Positive Seal and External Leakage Test, Section 11, Seat Leakage Test, Section 12, and Operation Test, Section 10, shall not result in the connection check valve remaining in the open position, nor shall the cylinder connection device or adapter become otherwise inoperative when tested as specified in 15.2. After the test, the cylinder connection device and adapter shall comply with the Leakage Tests, Section 11 and 12, Operation Test, Section 10, Abuse Test, Section 13, and when applicable, the Load Test, Section 14.
15.2 One sample of the cylinder connection device or adapter shall be used. With the supply side connected to a source of aerostatic pressure maintained at 100 psig (689 kPa) and secured to a test stand, the mating part that is closed or blocked is to be connected and disconnected from the cylinder portion using forces and torques as appropriate to make the connection at a rate not exceeding 20 cycles per minute for 10,000 cycles. The locking means for a CGA 810 device is capable of being defeated for the purpose of this test when the locking means incorporate materials complying with 6.2.
16 Bending Test
16.1 A cylinder connection device or adapter shall be capable of supporting a 50 inch-pound (5.7 Nm) bending moment without becoming inoperative or allowing leakage of gas when tested in accordance with 16.2.
16.2 Three samples of each cylinder connection device design shall be used. With the cylinder portion secured to a test stand and the appliance portion connected to the cylinder portion, a bending moment of 50 inch-pounds (5.7 Nm) shall be applied to the appliance portion for 15 minutes at a 90 degree angle from the longitudinal axis of the cylinder portion body and in the direction that is determined to be most severe. The moment shall be measured between the extreme inlet end of the cylinder portion and the extreme outlet end of the appliance portion. After application of the bending moment, each sample shall be subjected to the Positive Seal and External Leakage Test, Section 11.
18 Hydrostatic Pressure Strength Test
18.1 A cylinder connection device or adapter shall be capable of withstanding without rupture, separation or permanent distortion a hydrostatic pressure of 1250 psig (8.6 MPa), or five times the rated service pressure, whichever is greater, when tested in accordance with 18.2 and 18.3. “Without permanent distortion” is defined as compliance with the requirements of the Positive Seal and External Leakage Test, Section 11.
