The test method of NBS smoke density test box originated from NIST (the predecessor of NBS) of the National Institute of Standards and Technology of the United States. It has been popularized and applied in many testing fields. The test method can be used to detect smoke density of plastic products, rail transit non-metallic materials, ship non-metallic materials, wire and cable products, etc. According to the test method, the general applicable standards are ASTM E662, ISO 5659-2 and NES 711 smoke density test method in the Military National Standard; the test standard has more accurate test results than the previous method of building materials smoke density tester, and the optical sensor uses more precise photo multiplier tube. It can capture minute changes of smoke content in the box. If other testing devices are selected, such as Delegate gas detector, it can carry out smoke toxicity test of aviation standard and dock with FTIR Fourier transform device, which can accomplish qualitative and quantitative analysis of smoke content.
The new product NBS Smoke Density Chamber Versatile Fire Testing Instruments just meets the requirements, and is favored by the majority of laboratories, factories and relevant national testing agencies. The products tested are closely related to our lives and relate to various safety features in life.
The inner and outer walls are treated with Teflon coating, which can resist the erosion of strong corrosive gas and prolong the service life of the box greatly; High security performance,Installing explosion-proof aluminium foil device inside the box can reduce the personal risk of the tester in case of accident; High level of standardization, comply with many standards ASTM E662, ASTM F814, BS 6401: 1983, DIN 5510-2, ISO 5659-2:2012, NFPA 258CSN EN 45545-2+A1:2015, IMO FTPC Part 2, NES 711; High level of automation; The overall design of the test box is touch screen and can be connected to a computer to print test reports.
