Compliance overview
Scope and applicability
This standard applies to the design, production, and testing of motor vehicle spark arresters. It covers devices installed at the exhaust system outlet of motor vehicles to intercept and extinguish sparks and flames. It is mandatory for manufacturers producing exhaust spark arresters for the Chinese market. Other equipment utilizing spark arresters may refer to this standard for compliance.
Technical requirements
The standard specifies comprehensive technical requirements for motor vehicle spark arresters, categorized by installation type (generally equipped vs. temporarily equipped), structure (integral vs. non-integral), and cooling method (liquid cooling vs. non-liquid cooling). Key physical and structural requirements include appearance quality, strength under axial and radial loading, and specific material mandates such as stainless steel valve cores. Manufacturers must ensure robust structural integrity to prevent deformation under specified forces. Performance criteria dictate that the arrester must effectively extinguish sparks, limiting the escape of carbon particles to a specified ratio. Furthermore, when equipped, the device must not cause excessive power loss in the engine, nor should it increase exhaust noise or temperature beyond baseline levels. Liquid cooling type arresters have additional thermal and cooling medium requirements. The standard also introduces new requirements for product nameplates and electronic tags (RFID). Electronic tags must be permanently fixed, readable in metallic environments, and encode specific manufacturing and vehicle data according to GB18030.
Testing methods
Testing methods include visual inspection and dimensional measurement for appearance and strength. The spark extinguishing performance is evaluated using a specialized test apparatus with activated carbon particles. Engine performance is simulated using fans to measure power loss, noise, and exhaust temperature. Additional tests cover vibration resistance, drop tests for non-integral types, high-temperature endurance at 200°C, and comprehensive read/write tests for electronic tags.
FAQs
What products are regulated under GB 13365-2025?
GB 13365-2025 regulates motor vehicle spark arresters, including both generally equipped (permanent) and temporarily equipped types, as well as integral and non-integral designs.
Are there any updates from the previous version of GB 13365?
Yes, compared to GB 13365-2005, this version updates appearance and extinguishing performance requirements, and adds new requirements for strength, high-temperature resistance, product nameplates, and electronic tags.
Does GB 13365-2025 include requirements for electronic tags?
Yes, the standard mandates the use of electronic tags (active or passive) for non-integral arresters, specifying read/write distances, metallic environment performance, and data encoding rules according to GB18030.
