Cabinet gas fire extinguishing equipment
柜式气体灭火装置
GB 16670-2006 is a current mandatory Chinese national standard for Cabinet gas fire extinguishing equipment. It appears in the Machinery compliance cluster with a product safety focus and has an implementation date of Oct 1, 2006.
Applicability depends on product scope, certification route, competent authority notices and transition rules. Requst for the translation or verify source before using this record in a compliance decision.
Compliance overview
Scope and applicability
This standard applies to cabinet gas fire extinguishing equipment utilizing high-pressure carbon dioxide, heptafluoropropane, nitrogen, argon, and trifluoromethane. It covers the performance requirements, testing methods, and inspection rules for these self-contained, pre-engineered fire suppression units. This standard is not applicable to cabinet low-pressure carbon dioxide fire extinguishing equipment. Manufacturers of integrated fire suppression cabinets must verify compliance against this regulation.
Technical requirements
The standard mandates that the equipment must support both automatic and manual startup modes, with an optional mechanical emergency override. It sets specific parameters for working temperature ranges, storage pressure, and maximum discharge times. Manufacturers must ensure the device can successfully extinguish Class A and Class B fires within specified timeframes without re-ignition. It outlines strict criteria for component integrity, including structural strength, sealing performance, and temperature cycle leak requirements for agent cylinders and container valves. The standard also specifies that cylinders must use materials compliant with GB 5099 or GB 5100. All pressurized components must undergo rigorous hydrostatic strength and overpressure testing. Additionally, the standard defines the performance of safety and monitoring components. This includes the accuracy and color-coding of pressure gauges, the triggering thresholds for safety relief devices, and the alarm thresholds for leak detection components. Leak detection systems must reliably trigger visual and audible alarms when agent loss reaches 5% or pressure drops by 10%.
Testing methods
The standard specifies a series of evaluations including fire extinguishing tests for Class A (wood crib) and Class B (n-heptane) fires to verify actual suppression efficacy. It also mandates vibration tests to ensure mechanical integrity and agent retention during transport. Furthermore, components undergo salt spray corrosion tests and temperature cycling tests to verify long-term reliability in harsh environments. All components must pass these rigorous evaluations before market authorization.
FAQs
What products are regulated under GB 16670-2006?
GB 16670-2006 applies to cabinet high-pressure carbon dioxide, heptafluoropropane, nitrogen, argon, and trifluoromethane gas fire extinguishing equipment. It does not apply to cabinet low-pressure CO2 fire extinguishing equipment.
Are there any updates from the previous version of GB 16670?
The 2006 version added requirements for heptafluoropropane, nitrogen, argon, and trifluoromethane, while removing parameters for halon 1211 and 1301. It also introduced new requirements for fire extinguishing performance, containers, signal feedback components, and leak detection components.
How does GB 16670-2006 differ from international ISO standards?
GB 16670-2006 establishes specific national requirements for the cabinet form factor and integrated components. However, it extensively references GA 400 and GA 61 for the testing and performance of specific parts like nozzles, drivers, and controllers, aligning with broader Chinese fire safety standards.
