Western Australian Repealed Regulations Western Australian Repealed RegulationsThis legislation has been repealed.
(1) The methods and
apparatus prescribed for the testing of liquid petroleum gas for the purposes
of the Act are as follows:
(a) The
net heating value of gas fixed under section 6(2)(a) or (b) of the Act
shall be ascertained by analysing the gas by the method laid down for
ascertaining the hydro-carbon content of gas in the third edition of the
Handbook Butane-Propane Gases published in the year 1951 by Western Business
Papers of Los Angeles, U.S.A.; and thereafter calculating the heating value of
the gas by reference to the heating value of the hydro-carbons contained in
the gas, the heating values being ascertained from the standard tables showing
the heating values of hydro-carbons.
(b) The
method of testing liquid petroleum gas for the presence of mechanically
entrained water shall be by visual inspection of a sample in a clear glass
Dewar flask. The sample is to be taken from the bottom of the liquid petroleum
gas in a container containing that gas and precautions shall be taken to
exclude atmospheric moisture from the Dewar flask. A cloudy appearance of the
sample in the flask shall be regarded as proof of the presence of mechanically
entrained water.
(c) The
method and apparatus for the testing of liquid petroleum gas for the presence
of hydrogen sulphide shall be as follows:
Apparatus
— A glass vessel containing a strip of bibulous paper
moistened with a solution of acetate of lead containing 3.888 grams of
crystallised acetate of lead dissolved in 28.4 millilitres of water.
Method
— The gas shall be passed through the glass vessel containing
the strip of bibulous paper moistened with the solution of acetate of lead for
a period of at least 3 minutes, and if any discoloration of the paper is
found to have taken place, it shall be regarded as proof of the presence of
hydrogen sulphide in the gas.
(d) The
method and apparatus for the testing of liquid petroleum gas for the presence
and the quantity, if present, of mercaptan sulphur shall be in accordance with
the method known as the “Mercaptan Sulphate
Content — Silver Nitrate Method” and the apparatus for
the time being prescribed therefor as set down in test 1P.104 (as amended) of
the Standard Methods for Testing Petroleum and its Products , as published by
the Institute of Petroleum of England.
(e) The
method and apparatus for the testing of liquid petroleum gas for the total
sulphur content of the gas shall be in accordance with the method known as the
“Sulphur Content — Lamp Method” and the apparatus
for the time being prescribed therefor as set down in test 1P.107 (as amended)
of the Standard Methods for Testing Petroleum and its Products as published
by the Institute of Petroleum of England.
(f) The
method and apparatus for the testing of the vapour pressure of liquid
petroleum gas shall be in accordance with “The Liquefied Petroleum Gas
Vapour Pressure Test” as prescribed for the time being by the Natural
Gasoline Association of America Liquefied Petroleum Gas Specifications and
Test Methods.
(g) The
method and apparatus for the testing of liquid petroleum gas for the presence
of methane or for the proportionate content of C2 or C5 hydro-carbons shall be
in accordance with the “Low Temperature Distillation Method” as
laid down in the third edition of the Handbook Butane-Propane Gases published
in the year 1951 by Western Business Papers of Los Angeles, U.S.A.
(h) The
method and apparatus for the testing of liquid petroleum gas for evaporation
shall be in accordance with the “Weathering Test for Butane-Propane
Mixtures” as laid down for the time being in the Natural Gasoline
Association of America Liquefied Petroleum Gas Specifications and Test
Methods.
(2) Where a method, or
apparatus, is prescribed for any particular test of liquid petroleum gas for
the purposes of the Act, that test shall be carried out by that method and
with that apparatus.
