1 Name of Determination
This Determination is the Fuel Standard (Autogas) Determination 2003.
2 Commencement
This Determination commences on 1 March 2004.
3 Interpretation
(1) In this Determination:
autogas means liquefied petroleum gas that is supplied or represented as fuel suitable for motor vehicles but excludes liquefied petroleum gas supplied in cylinders.
(2) A reference in this Determination to ASTM International, European Committee for Standardisation (CEN), International Organization for Standardization (ISO) and Japan LP Gas Association is a reference to the standards development organisation of that name.
4 Fuel standards for autogas
(1) Autogas that contains a substance mentioned in the following table must not contain more than the amount mentioned for the substance.
| Item | Substance | Amount |
| 1 | Dienes | 0.3% (molar) |
| 2 | Residue on evaporation | 60 mg/kg |
| 3 | Sulfur (after stenching) | 50 mg/kg |
| 4 | Volatile residues (C5s and higher) | 2.0% (molar) |
(2) The standard for the presence of hydrogen sulfide in autogas is that the autogas tested must be ‘hydrogen sulfide negative’ within the meaning of the testing method mentioned for hydrogen sulfide in section 5.
(3) A property of autogas mentioned in the following table must meet the specification mentioned for the property.
| Item | Property | Specification |
| 1 | Copper strip corrosion | Class 1 |
| 2 | Water | No free water at 0°C |
| 3 | Motor octane number | 90.5 minimum |
| 4 | Odour | Detectable in air at 20% lower flammability limit |
| 5 | Vapour pressure (gauge) at 40°C | 800 kPa minimum 1 530 kPa maximum |
5 Testing methods
(1) Compliance with the standard set out in section 4 for the substance or property is determined by the testing method for the substance or property in the following table:
| Item | Substance or property | Testing method |
| 1 | Copper strip corrosion | EN ISO 6251 |
| 2 | Dienes | ISO 7941 |
| 3 | Hydrogen sulfide | EN ISO 8819 |
| 4 | Water | EN 589:2004 |
| 5 | Motor octane number | Composition by ISO 7941 Calculation by EN 589 Annex B |
| 6 | Odour | EN 589:2008 Annex A |
| 7 | Residue on evaporation | JLPGA-S-03 by mass method at 105°C |
| 8 | Sulfur | ASTM D6667 |
| 9 | Vapour pressure | ISO 8973 |
| 10 | Volatile residues (C5s and higher) | ISO 7941 |
(2) For subsection (1):
ASTM followed by an alphanumeric code means the testing method developed by ASTM International under the alphanumeric code.
EN or EN ISO followed by a number means the testing method developed by the European Committee for Standardisation (CEN) under the code and number.
ISO followed by a number means the testing method developed by the International Organization for Standardization (ISO) under the code and number.
JLPGA followed by an alphanumeric code means the testing method by mass developed by the Japan LP Gas Association under the alphanumeric code.
