Zhongnuo GB/T 20284 Single Unit Combustion Test Device for Building Materials and Productsmain purpose

Zhongnuo DT-1 typeSingle unit combustion testing device for building materials and productsthistest deviceA specialized testing instrument used to test the reaction of building materials or products (excluding flooring materials) to fire in a single combustion test, in order to determine their physical properties. thistest deviceMeet the requirements of the national standard for testing conditions,Standard basisTest procedures (methods).

passtest deviceAfter testing, the combustion performance (grade) of the sample can be determined, including quantitative (qualitative) testing parameters: sample combustion heat release rate, whether flame lateral propagation occurs, calculation of total smoke production of the sample (smoke production performance), and whether there are droplets and particles produced during sample combustion.

thistest deviceEquipped with multiple testing functions, providing high-quality and cost-effective testing for quality inspection departments and enterprisestool
