Decoration materials have become one of the most important sources of fire in urban buildings. Poisonous gas and smoke produced in fires are called “the number one killer of fires”. According to rough statistics, in the past fires in China, nearly 80% of casualties were caused by toxic gases and thick smoke from the burning of building materials. Therefore, it is of great significance to limit the smoke density produced by building materials to reduce the death rate of people in fire and ensure people’s life safety.
The smoke density tester for building materials is developed according to ASTM D2843 standard, which is suitable for testing smoke density grades of various building materials, such as composite materials, thermal insulation materials and coating materials. During the test, the flame directly impacts the sample, and after the material burns to produce smoke, the smoke density can be judged by blocking the transmittance of light.
The instrument box is treated with 304 stainless steel plus Teflon coating to resist the smoke erosion and prolong the service life. Equipped with transparent tempered glass door to facilitate observation and testing. The main burner and the auxiliary burner are equipped, which can impact the test samples and drips with flame. Real-time display of test data and smoke density curve, automatic output of computer, improve user experience.
