Limited Oxygen Index Tester with Standard ISO4598-2 For Fire Resistance Test Instrument

Equipment description:

Requirements for the assessment of polymer in the combustion performance test conditions, that determine the

polymer just to maintain the minimum combustion volume percentage of oxygen concentration. For plastic,

rubber, fiber, foam, film, and film and other materials, determination of combustion performance. Microcomputer

control, LCD display, data print, easy to operate, elegant appearance.

Application:

Limited Oxygen Index Test Apparatus is designed according to ISO4598-2 , it applies to analysis the minimum oxygen concentration needed to maintain combustion of the sample when the sample is under the test conditions specified in oxygen and nitrogen mixed gas;

This tester is installed with England imported oxygen sensor, and automatic control the oxygen and nitrogen flow with mass flow control meter. It is very easily and quickly to operate; It is used for evaluating homogeneity of solid materials, laminates, foam, film and thin film in the specified conditions of flammability.

Suitable for the determination of combustion properties of plastics, rubber, fiber, foam, film and film and textile materials, measuring the minimum oxygen concentration that will support combustion. The test specimens are burned in a precisely controlled atmosphere of nitrogen and oxygen .
