Abstract

A medical mouth mask flame retardant property test instrument belongs to the test instrument technical field, and is used to test the flame retardant property of medical mouth masks and all protective mouth masks. The test instrument consists of a combustion testing mechanism and a control mechanism which are connected together, wherein the combustion testing mechanism is a combustion testing box provided with a transparent observation door; the inside of the combustion testing box has a headform sample frame motion device, an ignition device, a flame temperature sensing device, a flame height measuring device and a combustion device; the control mechanism comprises a flame temperature display instrument, a combustible gas pressure-regulating device, a flame height regulating turnbutton, a headform motion control key, an ignition switch and other function-control keys. The invention completes the entire testing process through adopting the special human body headform sample frame and apparatus, automatic control of each motion and testing parts, the special structural design of a given gas source igniter and special air supply tube control mode, etc. Moreover, the test instrument has a simple structure, convenient use, high safety and reliability and high cost performance; meanwhile, the testing efficiency, testing cost, advanced technology and testing precision of the test instrument reach an advanced level.

Description

technical field [0001] The invention relates to a flame retardant performance testing instrument, in particular to a medical mask flame retardant performance testing instrument, which belongs to the technical field of testing instruments. Background technique [0002] The flame retardant performance test instrument for medical masks is mainly used to test the flame retardant performance of medical masks and all protective masks. The test principle is to install the mask sample to be tested on the head model frame to simulate the actual use state, and the mask will pass over the igniter with a constant flame height and flame temperature with the head model at a certain linear speed, observe the burning of the mask, and record The continuous burning and smoldering time of the mask sample after contact with the flame is used to evaluate whether the mask is qualified. [0003] Before the application of the present invention, there were various flame reta...
