CNG cylinders are approved subject to the following conditions—

  1. That they be permanently and clearly marked, either on a thickened portion of the cylinder or on a suitably attached metal plate, with characters not less than 6 mm high if space permits but in any case not less than 3 mm high, displaying the following information:
    (a) The specification to which the cylinder was manufactured.
    (b) The manufacturers name or mark, and the serial number of the cylinder.
    (c) The date of the original cylinder inspection and the identification mark of the inspection authority who made the inspection.
    (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 charging pressure of the cylinder at 15°C.
    (g) The nominal water capacity of the cylinder.
    (h) The tare weight of the cylinder.
    (i) An identification that the cylinder is suitable for use with CNG.
  2. That the cylinders be tested at periods not exceeding five years in accordance with the periodic test requirements laid down in the specification to which the cylinder was manufactured.
  3. That the cylinder 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 hand wheel to facilitate ease of opening and closing of the valve and shall be fitted with a pressure relief device comprising of a burst disc backed by fusible alloy. The fusible alloy is to have a nominal yield temperature of 100°C 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.
