Standards
This standard applies to the storage and handling of portable containers used for storage of Liquefied Petroleum Gases (LPG) and to the transportation of these containers.
This standard does not cover the storage, handling and transport of ammonia cylinders.
: This standard applies to the transport of petroleum and petroleum products by road tanker wagons licensed by the Guyana Energy Agency.
This standard applies to the transportation of petroleum and petroleum products by bulk transportation carriers licensed by the Guyana Energy Agency. This standard does not apply to road tanker wagons, marine transport and to the transportation liquid petroleum gases (LPG).
This standard specifies materials, construction, performance and testing requirements for low pressure single or two stage regulators for use with liquefied petroleum gas mixtures in vapour phase up to 4.903kN/m2 [50gf/cm2 or 500mm water column (WC)] outlet pressure.
1.1 This Guyana standard covers seven grades of diesel fuel oils suitable for various types of diesel engines. These grades are described as follows: 1.1.1 Grade No. 1-D S15—A special-purpose, light middle distillate fuel for use in diesel engine applications requiring a fuel with 15 ppm sulfur (maximum) and higher volatility than that provided by Grade No. 2-D S15 fuel. 1.1.2 Grade No. 1-D S500—A special-purpose, light middle distillate fuel for use in diesel engine applications requiring a fuel with 500 ppm sulphur (maximum) and higher volatility than that provided by Grade No. 2-D S500 fuel.2 1.1.3 Grade No. 1-D S5000—A special-purpose, light middle distillate fuel for use in diesel engine applications requiring a fuel with 5000 ppm sulphur (maximum) and higher volatility than that provided by Grade No. 2-D S5000 fuels. 1.1.4 Grade No. 2-D S15—A general purpose, middle distillate fuel for use in diesel engine applications requiring a fuel with 15 ppm sulphur (maximum). It is especially suitable for use in applications with conditions of varying speed and load. 1.1.5 Grade No. 2-D S500—A general-purpose, middle distillate fuel for use in diesel engine applications requiring a fuel with 500 ppm sulphur (maximum). It is especially suitable for use in applications with conditions of varying speed and load. 1.1.6 Grade No. 2-D S5000—A general-purpose, middle distillate fuel for use in diesel engine applications requiring a fuel with 5000 ppm sulphur (maximum), especially in conditions of varying speed and load. 1.1.7 Grade No. 4-D—A heavy distillate fuel, or a blend of distillate and residual oil, for use in low- and medium-speed diesel engines in applications involving predominantly constant speed and load.
The main text of this national standard contains a list of these parameters, their units and references to measurement standards. Informative annexes give examples of typical values for these parameters, with the main emphasis on health and safety. In defining the parameters governing composition, physical properties and trace constituents, consideration has also been given to existing natural gases to ensure their continuing viability.
The question of interchangeability is dealt with in Annex A (see Clause A.2).
Fuel meeting the requirements of this part of ISO 15403 should:
(a) provide for the safe operation of the vehicle and associated equipment needed for its fuelling and maintenance;
(b) protect the fuel system from the detrimental effects of corrosion, poisoning, and liquid or solid deposition;
(c) provide satisfactory vehicle performance under any and all conditions of climate and driving demands.
Some aspects of this part of ISO 15403 may also be applicable for the use of natural gas in stationary combustion engines.
1.1 This specification (see Note 1) covers grades of fuel oil intended for use in various types of fuel oil-burning equipment under various climatic and operating conditions. These grades are described as follows:
1.1.1 Grades No. 1 S5000, No. 1 S500, No. 1 S15, No. 2 S5000, No. 2 S500, and No. 2 S15 are middle distillate fuels for use in domestic and small industrial burners. Grades No. 1 S5000, No. 1 S500, and No. 1 S15 are particularly adapted to vaporizing type burners or where storage conditions require low pour point fuel.
1.1.2 Grades B6–B20 S5000, B6–B20 S500, and B6–B20 S15 are middle distillate fuel/biodiesel blends for use in domestic and small industrial burners.
1.1.3 Grades No. 4 (Light) and No. 4 are heavy distillate fuels or middle distillate/residual fuel blends used in commercial/industrial burners equipped for this viscosity range.
1.1.4 Grades No. 5 (Light), No. 5 (Heavy), and No. 6 are residual fuels of increasing viscosity and boiling range, used in industrial burners. Preheating is usually required for handling and proper atomization.
