We have received all the instruments, and will test them, for the moment we have very good feelings. Thank you.

—— Mr.Brett Cirulis

I really would like to work with YUYANG, their professional service on the laboratory solution and reliable products help me win much market!

—— Mr. Allan Ken

Nice cooperation! We appreciated for your company's kind support on our projects. Very good service.

—— Mr. Jaleshwar Prasad

I was set up your machine one week ago. İt’s good working. Thank you for all.

—— Ms.Erdem Traina

Quality is your factory culture, Quickly response is your core! Keep it and let YUYANG brand testing machine around the world.

—— Mr. Komarov Mihail

There are seldom suppliers willing to do small spare parts for us, while YUYANG spends time with us, only for three burners, we appreciate them.

—— Mr.Yavuz Yazgan

ASTM E84 Building Materials Surface Burning Characteristics Test Apparatus


This method is applicable to determine surface burning characteristics of building materials and flame propagation rate of exposed surfaces such as walls and ceilings (including solid plastics), at the same time measure smoke density.
This test method applies to the exposed surface which includes ceiling or walls, provided that the materials or the whole assembly, with its own structural quality or the aspect in which is tested and intended to use is able to support itself in position or being supported during the period of test. The method is used to determine the corresponding burning behavior of the material by observing the flame spread along the test specimen. Reports are made for the flame spread and smoke density developed and it is not necessarily a relationship between the two measurements.
ASTM E84: standard test method for surface burning characteristics of building materials
UL723: test for surface burning characteristics of building materials
1. Power: AC380V±10%
2. Max Power: 5KW
