(d) The date of any periodic cylinder test and the identification mark of the cylinder testing station who made each test.
(e) The cylinder test pressure.
(f) The design charging pressure of the cylinder at 15°C.
(g) The nominal water capacity of the cylinder.
(h) Where required by the marking provisions of the specification to which the cylinder was manufactured, the tare weight of the cylinder.

2. That they be clearly marked or labelled to indicate that the cylinder is suitable for use with CNG.

3. That they be provided with valve threads of the form specified in British Standard BS 341 “Valve Fittings for Compressed Gas Cylinders”.

4. That they be provided with a cylinder shut off valve designed for a working pressure of 16.5 MPa and capable of withstanding the test pressure of the cylinder. Cylinder shut off valves shall be fitted with a handwheel to facilitate ease of opening and closing of the valve and shall be fitted with a pressure relief device, which remains in contact with the gas contained in the cylinder whether the handwheel is in the open or closed position, comprising of a burst disc backed by fusible alloy. The fusible alloy is to have a nominal yield temperature of 100° Centigrade and the burst disc shall yield at a pressure of not less than 24.75 MPa and not more than the test pressure of the cylinder. Cylinder valves shall be provided with an outlet thread of ¼ inch NPT (female) and a stem thread compatible with the cylinder neck thread.

5. That they shall not be charged with CNG to a greater pressure than 16.5 MPa at 15° Centigrade.

6. That they be tested at periods not exceeding 5 years in accordance with the requirements of Australian Standard AS 2337-1980 and in accordance with the periodic test requirements laid down in the specification to which the cylinder was manufactured.
