Installing the Limiting Oxygen Index Tester

Author:QINSUN Released in:2023-08 Click:21

The limit oxygen index tester is an experimental instrument used to determine the oxygen concentration (percentage by volume) required for polymers in the combustion process. The test equipment independently developed and produced by our company qisnun Precision Electromechanical Technology Co., Ltd. has high cost performance and comprehensive after-sales service. The value of the oxygen index of the polymer is the volume percentage of oxygen in the gaseous mixture of oxygen and nitrogen necessary for the substance to burn 50 mm or burn for 3 minutes after ignition.

Applicable standards:

GB/T2406.2-2009, GB/T5454-1997, GB/T10707-2008, GB/T8924-2005, GB/T2406-93, GB /T10707-2008, GB/T8924-2005

Connect the nitrogen and oxygen connectors on the rear panel of the control box to the outlet ports of the pressure reducing valves of the oxygen and nitrogen cylinders with the plastic reinforced tubes included in the accessories, and tighten secure them with tube clips. Steel cylinders and pressure reducing valves are prepared by the user.
