Introduction
This article defines, explains and evaluates the requirements of the GB 17258-1998 standard for motor vehicle use of compressed natural gas cylinders. This standard was issued by the State Council of the Peoples Republic of China and was developed to provide a consistent and standardized procedure for the safe use of compressed natural gas cylinders in motor vehicles.
Definition
The State Council of the Peoples Republic of Chinas GB 17258-1998 Standard for Motor Vehicle Use of Compressed Natural Gas Cylinders is a national consumer-oriented instrument governing compressed natural gas cylinders used as a fuel to power motor vehicles in the Peoples Republic of China. The standard applies to all types of motor vehicle powered by compressed natural gas, including passenger cars and light trucks. The purpose of the standard is to ensure the safe, efficient, and economic use of the vehicles by preventing the release of hazardous or polluting material and by providing for the safety of passengers and personnel in the vicinity.
Requirements
The GB 17258-1998 standard contains requirements for the design, inspection, testing, and use of compressed natural gas cylinders used in motor vehicles. It specifies that the cylinders must be constructed from steel, aluminum, or other materials of an equivalent strength and durability. The cylinders must meet specifications set by the state authority, including minimum distances between the cylinder and combustible materials, minimum pressure ratings, minimum wall thickness, and those specified in the state regulations. The standard requires that each cylinder be fitted with a pressure-relief device, leak detector, and pressure-shutoff valve, and that all necessary safety information is provided with the cylinder.
The standard also outlines requirements for the installation and maintenance of the cylinders and their auxiliary equipment in the motor vehicle. The cylinders must be installed in accordance with the manufacturers instructions, and any modifications must be approved by a qualified person. The manufacturer must provide instructions for the use of the cylinder, including instructions on the proper filling, unloading, and handling of the cylinders. The standard also requires that all cylinders comply with the relevant legislation and that regular inspections, tests, and maintenance be performed on all cylinders and related systems.
Evaluation
The GB 17258-1998 standard is an important part of the motor vehicle safety regulations in the Peoples Republic of China. The standard provides specific requirements for the design, installation, maintenance, and use of compressed natural gas cylinders in motor vehicles, ensuring that the cylinders are safe to use and reducing the risk of accidents. The requirements of the standard are comprehensive and provide a strong basis for the safe operation of motor vehicles powered by compressed natural gas cylinders.
The GB 17258-1998 standard is a comprehensive guide for the safe use of compressed natural gas cylinders in motor vehicles. Its provisions are well-outlined and provide a good framework for the safe operation of motor vehicles and the cylinders used to power them. The standard is an important contribution to motor vehicle safety in the Peoples Republic of China and should be adhered to by manufacturers and users alike.
