Escopo e aplicabilidade

This standard applies to the design, manufacturing, and inspection of household combustible gas detectors used in residential environments to detect natural gas, liquefied petroleum gas, artificial coal gas, and their incomplete combustion products. It is specifically targeted at detectors intended for home use, distinguishing them from industrial or commercial models covered in other parts of the GB 15322 series. The standard classifies detectors into system-based detectors and stand-alone detectors.

Requisitos técnicos

The standard outlines comprehensive technical requirements for household gas detectors. It specifies general performance criteria, including power supply configurations, alarm set points (typically within the 5%LEL to 25%LEL range), and enclosure protection ratings (IP30). Detectors must feature clear visual indicators for various states—normal monitoring, fault, and alarm—and include a dedicated yellow indicator for gas sensor life expiration. Manufacturers must ensure detectors have structural anti-detachment measures for sensors and clear polarity protection for power inputs. Additional functional requirements cover control output capabilities, particularly for triggering electromagnetic gas emergency shut-off valves. The standard mandates specific response times, alarm sound pressure levels, and wireless communication functions for transmitting event data to manufacturer platforms. Detectors must also maintain historical event logs, including alarm, fault, and power cycle records, with specified minimum storage capacities. The standard details robustness criteria against environmental and electromagnetic interference. This includes tolerance to temperature variations, humidity, vibrations, and drops. Furthermore, detectors must demonstrate anti-poisoning performance and resistance to interference from common household contaminants like cooking oil fumes and alcohol vapors. Specific testing parameters for these conditions are defined in the full document.

Métodos de ensaio

Testing procedures are designed to verify compliance with the technical requirements. Key tests include the alarm action value test to determine the exact concentration at which the detector triggers, and the response time test to measure the delay between gas exposure and alarm activation. Environmental tests simulate extreme conditions such as high/low temperatures, constant and alternating damp heat, and temperature shocks. Electromagnetic compatibility (EMC) tests assess resilience to electrostatic discharge, radiated electromagnetic fields, and electrical fast transients. Specialized tests like the anti-edible-oil-fume interference test and the anti-poisoning performance test ensure reliability in typical household scenarios.

Perguntas frequentes

What products are regulated under GB 15322.2-2026?

GB 15322.2-2026 regulates household combustible gas detectors designed for residential use, including both system-based and stand-alone detectors that monitor gases like natural gas, LPG, and carbon monoxide.

Are there any updates from the previous version of GB 15322.2?

Yes, the 2026 version introduces several updates from the 2019 edition, including new requirements for wireless communication functions, anti-detachment measures for gas sensors, resistance to cooking oil fumes, and the inclusion of a product quality safety traceability code.

Does GB 15322.2-2026 specify requirements for wireless communication?

Yes, detectors with wireless capabilities must transmit event information—such as alarms, faults, and sensor life expiration—to the manufacturer's platform within 2 minutes. They must also have a unique identity identifier code as specified in the standard's appendix.
