Flammability of Polymers test

Most plastics are carbon-based materials and will burn and give off gases and smoke when subjected to a flame. Plastics are excellent fuels but are generally classed as ordinary combustibles and fall into the same category as wood, leather and many other common materials. All of these materials will...

Operating Method of Oxygen Index tester

This method describes a procedure for determining the relative flammability of organic films and reinforced composites by measuring the minimum concentration of oxygen in a gaseous mixture of oxygen and nitrogen that will just support combustion. It is based on ASTM Standard D2863-77 but modified to...

Test method for Fogging Tester

The term Fogging refers to the film that collects on the inside of vehicle window glass. Of particular interest is the windshield, because this film can both limit light transmittal as well as refract the light that is transmitted, impairing visibility and creating safety concerns. A fogging test sy...

The Optical Properties Test on Shading Fabric

In order to study the heat insulation and indoor light adjusting ability of fabric, the optical properties of usual shading fabric were tested using spectrophotometer which measurement range is 190nm~3300nm. Under different open porosity, the ultraviolet transmittance, solar direct transmittance, so...
