Conditions of Approval

LPG fuel containers are approved subject to the following conditions—

1. That they be permanently and clearly marked, 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 container was manufactured.

   (b) The manufacturer’s name or mark and the serial number of the container.

   (c) The date of the original container inspection and the identification mark of the inspection authority who made the inspection.

   (d) The date of any periodic container test and the identification mark of the cylinder testing station who made each test.

   (e) The container test pressure.

   (f) The nominal water capacity of the container.

   (g) The tare weight of the container.

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

3. That they be provided with valve threads and fittings which provide the following functions:

   (a) Filling connection incorporating a non return valve.

   (b) Service valve incorporating an excess flow valve.

   (c) Contents gauge.

   (d) Pressure relief valve.

   (e) Fixed liquid level indicator.

   (f) Automatic fill limiter which prevents the container being filled beyond 85 percent of the total container capacity.

   Note: Where both items 3 (e) and 3 (f) are not currently fitted to a container, then both items shall be fitted before a new installation of the container, or at the next test of the container, or if the container is removed from the vehicle for any reason, whichever occurs first. If an authorised person (defined in the Traffic Regulations 1976, Amendment No. 7), or a cylinder testing station, considers that the fitting of item 3 (f) is not practicable due to the construction of the container, then a dispensation shall apply allowing the container to be used without item 3 (f). This dispensation shall only be valid until a suitable design of 3 (f) becomes available in New Zealand.

   Valves and fittings shall have a service pressure rating of at least that of the container to which they are fitted and shall be dimensioned, threaded and marked in accordance with the requirements of section 2.2 of New Zealand Standard NZS 5422:1987 “The Use of LPG and CNG Fuels in Internal Combustion Engines—Part 1 LPG Fuel”.

4. That they be tested prior to installation, and at periods stipulated in the Traffic Regulations 1976, Amendment No. 15, in accordance with the requirements of Australian Standard AS 2337.1—1987 or in accordance with the periodic test requirements laid down in the specification to which the container was manufactured.

5. That they be fitted to a motor vehicle in such a position that they will not be subject to the direct rays of the sun, either by fitting them within a suitable vehicle compartment, or by providing a suitable shield if the cylinders are fitted to the exterior of the vehicle.

6. The terms of this approval do not allow the continued importation of such LPG fuel cylinders and it does not apply to cylinders which have not been installed in a motor vehicle by 31 December 1985.

   Note: The effect of this notice is to allow the continued use of LPG fuel cylinders which are known to have been imported into New Zealand prior to the introduction of the Dangerous Goods (Class 2—Gases) Regulations 1980 and which were acceptable under the previous dangerous goods requirements, but whose working pressure rating would disqualify them for approval for general use under the Traffic Regulations 1976. They are approved subject to the additional proviso that they must not be exposed to direct sunlight (to reduce the possibility that solar radiation would raise the temperature of the contents of the cylinder such that the developed pressure of the cylinder contents exceeded the working pressure rating of the cylinder).

   Dated at Wellington this 6th day of October 1987.
