Standards:

GB/T 8626-2007 Building materials flammability test method ISO11925-2:2002 Reaction to fire tests--Ignitability of building products subjected to direct impingement of flame — Part 2: Single-flame source test .

Applications:

Building materials flammability testing machine is designed and manufactured based on GB / T 8626-2007 "building materials flammability test method", suitable for determining whether the building material is flammable. 

Product Information:

Building materials Flammability tester is used to  determine the flammability of building products by  direct impingement of the vertical placed sample with a small flame in the absence of external radiation conditions. The false flame height can make it very easy to locate the placement of the specimen. The flame height measuring device can be very accurate to determine the standard required flame size. Programmable relays displays the test time, the specimen burning state, and gas access time during the entire test. The operator can clearly observe the entire process of the test.

Features:
 1, Test chamber, test stand, the specimen holder, etc. are made of stainless steel, to ensure the equipment’s corrosion resistance, and enhance the service life of the equipment, making the chamber appearance of excellent quality with strong mechanical strength.
2, Combustion control system uses propane solenoid valve for automatic control of propane gas on-off, to ensure the safety of equipment.
3, The burner is equipped with a standard flame height scale. The adjustment  of burner flame is convenient, flexible and accurate.
4, The specimen folder is produced strictly as per the structure required by the standard with fast specimen installation speed and good combustion test process.
5, Key switch design, servo motor control, reset control.
6, Carriage movement system uses the upper and lower displacement limit switch, and the angle of flame is accurate in the test.
7, The carriage is equipped with a drawbar, and it is easy to adjust the distance between the positioned flame height and the bottom of the specimen center.
8, The entire equipment is airtight, using pressure explosion-proof nylon tube made from good materials, effective anti-corrosion, so that the life of the test equipment is longer.
9, The central control device use imported Omron programmable relay with a high degree of automation.
10, During the automatic control process, take every step according to the detailed product manual. The whole test operation is easy to learn.
