Liquefied Petroleum Gas (LPG) is a type of fuel used in many aspects of daily life. In China, it is used in domestic cooking, heating and vehicle transportation. GB 11174-1997 lays out the technical specifications and safety requirements of LPG.
The specification is provided by the Standardization Administration of the Peoples Republic of China and sets out the technical requirements and methods of test for liquefied petroleum gas. The purpose of the specification is to ensure that LPG is used safely and efficiently.
LPG is composed of hydrocarbons derived from petroleum and natural gas production. It is a flammable, colorless and odorless mix of hydrocarbon compounds that exist as a vapor at normal temperature and pressure, and can easily be converted into liquid form by applying moderate pressure.
The specification is split into several sections, covering the requirements and tests for safety, properties and other characteristics of different types of LPG.
The safety requirements of LPG are among the most highly regulated of any commercial fuel. The specification covers a range of tests to ensure that LPG has the correct flammability and toxicology ratings, odorisation and gas composition in order to meet safety standards.
In addition, the specification covers the properties of the gas and detailed tests to check them. Properties such as vapor pressure, boiling point, water solubility and flash point are tested. These tests are used to ensure that the LPG is fit for use and will not cause any harm when used correctly.
The specification also contains standard requirements for the manufacture, packaging and transport of LPG, as well as detailing the necessary instruments and supplies required for the testing process.
LPG has become increasingly popular in China due to its efficiency, safety and affordability. It is used both domestically and commercially, and can be safely stored in tanks or cylinders for transport purposes. GB 11174-1997 provides a comprehensive framework for the use and safety of LPG, and the tests and requirements outlined in the specification help to ensure safe and reliable LPG use in China.
