Alcance y aplicabilidad

This standard applies to safety helmets used for head protection in industrial and occupational workplaces. It is mandatory for all manufacturers producing head protection for the Chinese market. It explicitly excludes head protection designed for firefighting, emergency rescue, sports, and vehicle use. The standard covers both ordinary type (P) and special type (T) helmets.

Requisitos técnicos

GB 2811-2019 specifies stringent material, structural, and performance requirements for safety helmets. It mandates that materials must be non-toxic, non-allergenic, and recycled materials are strictly prohibited for load-bearing components such as the shell and headband. The standard defines critical basic performance criteria, including impact absorption and puncture resistance. Helmets must undergo specific pre-treatments—such as high temperature, low temperature, water immersion, and ultraviolet (UV) exposure—before testing. For special type (T) helmets, the standard outlines additional performance requirements. These include flame retardation, lateral rigidity, electrical insulation (Class G and E), anti-static properties, and low-temperature resistance. New additions to this version include requirements for extreme high-temperature resistance (+150°C) and resistance to molten metal splash. Manufacturers must ensure these specialized helmets do not exhibit penetration, excessive deformation, or prolonged afterflame during testing.

Métodos de ensayo

Testing procedures are primarily conducted in accordance with the referenced standard GB/T 2812. Key evaluations include impact absorption tests using a headform to measure force transmission, and puncture resistance tests using a steel cone. Specialized assessments involve lateral rigidity testing, electrical insulation leakage current measurement, and anti-static surface resistance testing. For extreme conditions, the standard introduces specific pre-treatment apparatuses, such as a high-temperature chamber (detailed in Annex A) and a molten metal pour test (detailed in Annex B).

Preguntas frecuentes

What products are regulated under GB 2811-2019?

GB 2811-2019 applies to safety helmets used in general industrial workplaces. It explicitly excludes head protection used for firefighting, emergency rescue, sports, and vehicles. It is a mandatory standard for industrial head protection in China.

Are there any updates from the previous version of GB 2811?

The 2019 version introduces new classification categories (Type P and Type T), adds requirements for extreme high temperature resistance (+150°C) and molten metal splash resistance, and modifies requirements for mass, wearing height, and ventilation holes. It also updates the permanent marking requirements.

How does GB 2811-2019 differ from international standards like ISO or EN?

GB 2811-2019 references international standards like ANSI/ISEA Z89.1 and EN 397 in its bibliography. However, it establishes China-specific classification codes (e.g., T, LD, J, MM) and distinct testing parameters, particularly for the newly added extreme high temperature and molten metal splash performance tests.
