Abstract

The invention provides an oxygen index tester and belongs to the technical field of plastic testing. The oxygen index tester comprises a tester body and a suspension support, wherein the tester body comprises a housing, a testing module, an oxygen pipe and a nitrogen pipe. The testing module is arranged in the housing, and the oxygen pipe and the nitrogen pipe respectively penetrate through the housing and are communicated with the testing module. The suspension support comprises a support body, a suction disc and connecting rods, wherein the cross section of the support body is arc-shaped, stepped holes are formed in the center of the support body, the connecting rods are arranged in the stepped holes, a press cover is arranged at one end of each connecting rod, the other end of each connecting rod extends out of the corresponding through hole and is connected with the suction disc, connecting buckles are arranged on the support, and buckles and fixing seats are arranged at the upper portion of the housing and are used for supporting the housing. The using environments of the oxygen index tester are increased by arranging the suspension support which can be suspended on the wall face, the stability of the oxygen index tester can be always kept, and testing results can be more accurate.

Description

technical field [0001] The invention relates to the technical field of plastic testing, in particular to an oxygen index tester. Background technique [0002] Oxygen index meters can determine the oxygen index of a variety of materials such as plastics, rubber, textile fabrics, wood, foam and other polymeric materials. Oxygen index (LOI) refers to the minimum oxygen concentration required for a material to burn flamingly in an oxygen-nitrogen mixed flow under specified conditions. It is expressed as the numerical value of the volume percentage of oxygen. According to the national standard Gβ / T2406.2-2009 "Determination of Combustion Behavior of Plastics by Oxygen Index Method", the test principle is: a sample of a specified size is vertically supported in a transparent combustion cylinder of a specified size, and there is a certain concentration in it from bottom to top Use the igniter to ignite the upper end of the sample with the mixed gas of oxygen and nitrogen flowing ...
