Two mandatory national standards focusing on early warning of gas safety sources have been officially released.

Targeted measures: tailored solutions for each of the two scenarios.

Gas safety is a matter of vital importance to every household and public safety. The two newly released national standards focus on the urgent needs of current gas safety governance, and provide precise technological upgrades for two typical application scenarios: industrial and commercial, and residential. They aim to improve safety assurance capabilities from the source of early warning and provide strong standard support for preventing and mitigating major safety risks.

Industrial and commercial scenarios: Enhancing tolerance to extreme environments

GB 15322.1—2026, "Combustible Gas Detectors Part 1: Point-type Combustible Gas Detectors for Industrial and Commercial Use," mainly specifies the design, manufacturing, and inspection requirements for point-type combustible gas detectors used in industrial and commercial settings.

In response to the complex and harsh environments of industrial and commercial applications, the new standard focuses on enhancing the detectors' ability to withstand extreme environments . The standard specifically adds stringent testing items such as salt spray and environmental corrosion tests , aiming to significantly improve the reliability and lifespan of products in high-humidity, high-salt-spray, and highly corrosive environments such as chemical plants, coastal areas, and restaurant kitchens . This means that future industrial and commercial combustible gas detectors will have stronger resilience, ensuring they don't fail at critical times.

Home use scenario: Comprehensively solve the pain points of false alarms and missed alarms

GB 15322.2—2026, "Combustible Gas Detectors Part 2: Household Combustible Gas Detectors", mainly specifies the design, manufacturing and inspection requirements for household detectors that detect combustible gases such as natural gas, liquefied petroleum gas, and manufactured gas and their incomplete combustion products.

Addressing long-standing pain points for home air quality detectors, such as drastic temperature fluctuations in kitchens, interference from cooking fumes, and inconsistent product quality , the new standard comprehensively improves the detectors' anti-interference performance . The standard specifically adds test items that closely reflect real-world usage scenarios, including resistance to temperature shock, alternating damp heat, and resistance to cooking fume interference , ensuring that products can operate stably in the complex air environment of a kitchen.

Of particular note is the new standard's explicit regulation on alarm response time: requiring detectors to issue alarm messages within a timeframe of no less than 15 seconds and no more than 60 seconds . This quantitative indicator aims to effectively prevent false alarms and unexpected alarms in practical applications, while ensuring timely response in the event of a real leak, thereby significantly improving the product's early warning accuracy, stability, and lifespan, truly achieving zero false alarms and zero missed alarms .

Collaborative Advancement: Strengthening the Gas Safety Early Warning System

It is understood that the State Administration for Market Regulation, together with the National Fire and Rescue Administration and other relevant industry authorities, will intensify efforts to promote the standards and facilitate their early implementation . This move aims to effectively improve the performance and reliability of combustible gas detectors, eliminate outdated and substandard products, and guide the industry towards high-quality and high-reliability development.

Industry experts say the release of the two new national standards marks a new stage in my country's gas safety early warning management, one that is more refined and scientific. By focusing on equipment at the source of early warning, a more accurate and efficient gas safety early warning system will be effectively built, providing a solid guarantee for the safety of people's lives and property and public safety.
