LIQUEFIED PETROLEUM GAS (LPG)-
ORDORIZED COMMERCIAL PROPANE HD-5 11/17/11 GMS 9010
1. DESCRIPTION:
LIQUEFIED PETROLEUM GAS (LPG)
- ODORIZED COMMERCIAL PROPANE HD-5
2. SCOPE:
This specification defines the properties of Liquefied Petroleum Gas (LPG)-Odorized Commercial
Propane HD-5.
3. APPLICATION:
Commercial propane is a hydrocarbon product for use where high volatility is required. It is suitable for
certain low severity internal combustion engine applications. At Olympian, generators and other
equipment using combustion engines are tested using LPG, typically available in USA and Canada,
with chemical and physical properties listed below. The variations from this fuel standard can lead to
lower power output, pre-ignition, detonation and corrosion.
4. CHEMICAL DATA:
4.1 Chemical Name: Propane
4.2 Chemical Family: Liquefied Petroleum Gas (Paraffinic Hydrocarbon)
4.3 Molecular Formula: C
