English version machine-translated from the Vietnamese original — under review.
Over nearly 2 years, NSCA carried out dozens of different rigorous fire tests on many types of dampers across many size ranges, achieving the highest fire-resistance classes on the market for both E dampers and EI dampers, from small sizes (1200x800) to large dampers (2000x1000), as well as assembled dampers assessed for extended application with unlimited width and heights of up to 1600mm. NSCA is a pioneer that has consistently pursued registration for representative sample certification in the spirit of Decree 136. On 13 March 2023, the Police Department of Fire Prevention, Firefighting and Rescue granted Representative Sample Certificates for all E and EI damper models manufactured by NSCA.
These certificates confirm that the E and EI fire dampers manufactured and supplied by NSCA are fully qualified to meet the fire safety requirements of QCVN 06:2022/BXD. The damper models manufactured by NSCA can supply the market with different types of dampers, in many sizes, as required by most civil and industrial projects nationwide. The inspection certificates for the dampers supplied to each project will be provided by NSCA at the time of delivery. This helps projects stay in control of their work and speeds up acceptance, handover and putting the building into service!
