適用範囲

This standard specifies the general requirements for preventing electrostatic accidents, including management measures, hazardous area classifications, and protection measures for solid, liquid, gaseous, and powder materials. It applies to the design and management of electrostatic hazardous areas. This standard is mandatory for facilities handling flammable materials where electrostatic discharge poses an ignition risk. It does not apply to the prevention of electrostatic hazards for explosives, electric initiating devices, and fireworks. (GB 12158-2024 replaces GB 12158-2006 and GB 13348-2009).

技術要求

The standard outlines comprehensive electrostatic protection measures across various operational environments. It defines the limits for different electrostatic discharge types, such as spark and brush discharges, and their ignition capabilities. Facilities must implement basic anti-static measures, including reducing static charge generation, accelerating static dissipation, and adopting supplementary shielding. Grounding requirements are strictly specified, indicating that all insulated static conductors in hazardous areas must be grounded, with specific resistance limits for grounding and leakage. For liquid materials, the standard details operational protocols for filling, sampling, and mixing to prevent static accumulation. It is mandatory to control flow velocities, ensure proper relaxation times, and use grounded equipment during the transfer of flammable liquids. Requirements for road tankers, ships, and aircraft refueling are also established to mitigate electrostatic risks during fluid transfer operations. Regarding gaseous and powder materials, the standard mandates the use of inerting technologies, conductive piping, and proper grounding of dust collection systems. Facilities handling combustible dust must ensure all metal equipment and piping are equipotentially bonded and grounded to prevent dust explosions. The standard also specifies requirements for human electrostatic protection, including the use of anti-static clothing and footwear in designated zones.

試験方法

The standard references various testing methods to ensure material compliance, such as conductivity testing for conveyor belts according to GB/T 3684 and resistance measurement for hoses per GB/T 9572. It also involves evaluating the minimum ignition energy (MIE) of materials and measuring surface and volume resistivity to classify materials as static conductors, sub-conductors, or non-conductors. Regular monitoring and third-party calibration of electrostatic monitoring devices are required to maintain compliance.

よくある質問

What products or facilities are regulated under GB 12158-2024?

It regulates the design and management of electrostatic hazardous areas, including facilities handling solid, liquid, gaseous, and powder materials where static discharge could cause fire or explosion.

Are there any updates from the previous version of GB 12158-2024?

Yes, it integrates and replaces GB 12158-2006 and GB 13348-2009, adding new terms, management measures, hazardous area classifications, and requirements for insulating dust filters and inerting technologies.

Does GB 12158-2024 align with international standards?

The standard references international practices and standards like IEC TS 60079-32-1 and NFPA 77 in its bibliography, ensuring its methodologies for electrostatic hazard prevention are aligned with global best practices.
