1. Citation
These regulations may be cited as the Gas Safety (Gas Quality) Regulations.

2. Interpretation
In these regulations, unless the context otherwise requires—
relative density (相對密度), in relation to any gas, means the ratio of the mass of a volume of the gas when containing no water vapour to the mass (expressed in the same units) of the same volume of air containing no water vapour under the same conditions of temperature and pressure;
sulphur (硫磺) includes sulphur compound;
Wobbe number (華白指數) means the number derived by dividing the calorific value of any gas by the square root of the relative density of the gas.

3. Standard of pressure
No person shall supply any gas through—
(a) a service pipe; or
(b) a gas main,
at a pressure which is less than the pressure specified in column 2 of the table to this regulation in relation to the range of Wobbe numbers specified opposite thereto in column 1 of that table applicable to the gas supplied.Table
Pressure of Gas Supplied Through Service Pipes and Gas Mains

Column 1  Column 2   Range of Wobbe numbers in Megajoule per cubic metre  Pressure measured in kPa in excess of atmospheric pressure   Not more than 31   0.5   More than 31 but not more than 40   1   More than 40 but not more than 72   1.25   More than 72   2 

4. Standard of purity
No person shall supply any gas specified in column 1 of the table to this regulation which contains more than the proportion of sulphur specified opposite thereto in column 2 of that table.TablePurity of Gas Supplied

Column 1  Column 2   Type of gas  Maximum proportion of sulphur permitted   Town gas  5 mg of hydrogen sulphide per standard cubic metre   Natural gas  5 mg of hydrogen sulphide per standard cubic metre   Liquefied petroleum gas  0.02% by mass total sulphur 

5. Distinctive smell
(1) Subject to subregulation (2), no person shall supply any gas which does not possess a distinctive smell.
(2) Subregulation (1) shall not apply to the supply of gas for use in—
(a) cigarette lighters; or
(b) aerosol cans.

6. Offences
Any person who contravenes regulation 3, 4 or 5(1) commits an offence and is liable on conviction to a fine at level 3 and, in the case of a continuing offence, to a daily penalty of $1,000.
