Detailed description

Description

The building materials flammability test furnace is in the normal combustion environment, with a small flame directly impacted the vertical specimen to determine the combustibility of the building products. The flammability test furnace for building materials is based on the principle of Kleinbrenner (Klein Brenner), which is directly impacted by a vertical flame. It is used to determine the combustion performance of B grade building materials (namely, the judgement of burning performance and flame retardant grade B of building materials).

Standards

EN ISO 11925-2

Features

①The operation in line with ergonomic design,test all through the touch screen operation,high degree of automation.Otherwise, the previous test results can be stored and can access the previous test data.

②Controllable automatic lifting of servo motor drive pattern frame.

③The Bunsen Burner can be advanced and retreat and adjusted.

④1.5mm stainless steel plate box

⑤Double angle observation test of 2 heat-resistant tempered glass doors, double (with lock) is convenient and practical.

⑥High pressure automatic ignition and durable combustion.

⑦The point fire source can be automatically tilted by 45 degrees.

⑧The height of the flame is adjusted by the precision regulating valve.
