2.3.2 The cylinder portion is to be connected to a regulated source of aerostatic pressure maintained at 25 psi (172 kPa) and the appliance portion is to be capped, and a means connected to verify flow. While separated, both parts shall be submerged in a water bath maintained at approximately 70°F (21°C). AllI trapped air is to be expelled from the cylinder portion. While submerged, the appliance portion is to be connected to the cylinder portion,as intended in service, and observed for 30 seconds for bubbles which would indicate that a leak-tight seal was not achieved before the flow of gas was permitted; no external leakage shall be observed. The test shall then be repeated at 100 psi (690 kPa) and 250 psi (1.7 MPa) or rated service pressure, whichever is greater.
Note: This recognizes that the seal and flow of gas may be coincident, and is acceptable.
2.5.1 The connection check valve provided in the cylinder connection device, shall not allow leakage of gas by the insertion of simple tools into the recess of the cylinder portion with a force less than 5 pounds (22 N) when tested in accordance with 2.5.2.
2.5.2 With the cylinder portion secured to a test stand and subjected to a source of aerostatic pressure maintained at 50 psi (345 kPa), a force gauge fitted with a radiused end probe of an appropriate diameter, to simulate a simple tool such as a screwdriver, penknife, or needle-nose pliers, shall be inserted into the recess and the force needed to allow the flow of gas shall be measured.
2.7.2 With the supply side of the cylinder portion connected to a source of aerostatic pressure maintained at 100 psi (690 kPa) and secured to a test stand, the mating appliance portion 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 may be defeated for the purpose of this test. If the locking means is defeated, the locking means must be tested separately, per this paragraph.
2.8.2 With the cylinder portion of the device secured to a test stand and the appliance portion of the device connected to the cylinder portion of the device, a bending moment of 50 pound-inches (5.7 Nom) shall be applied to the appliance portion for 15 minutes at a 90 degree (3.14 rad) angle from the longitudinal axis of the cylinder portion 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 of the device and the extreme outlet end of the appliance portion of the device.CSA 6.25 pdf download.
