Scope
NB/T 10757-2021 is the English-translated version of 矿用泡沫降尘装置.
NB/T 10757-2021 is the product standard for foam dust suppression devices used in mines, which mix foam concentrate with water and air to generate foam that blankets and captures dust at its source.
It defines model designations and working conditions, sets technical requirements and describes the test methods, inspection rules, and marking, packaging, transport and storage.
The references show what is tested beyond the device itself: acute oral toxicity and skin irritation of the foaming agent, metal corrosion, flame retardancy and antistatic properties of polymer parts, and hose performance.
Terms such as foam concentrate and premixed foam solution are aligned with the foam fire extinguishing design code GB 50151-2010. Equipment makers and mine ventilation and dust control departments use it. Issued on 16 November 2021, it has applied since 16 February 2022.
