Description

Vertical combustion testing device Technical Field The utility model belongs to the technical field of machinery, and relates to a vertical combustion testing device. Background The flame retardant property refers to the ability of a material to inhibit combustion, slow flame propagation or self-extinguish when contacting a fire source, and is an important index for measuring the fireproof safety of the material. Among flame retardant standards, the UL94 standard is a standard commonly used for testing the combustion performance of materials, and is formulated by the american security laboratory (UL), so that the UL94 standard is applicable to not only conventional electronics and electrical industries, but also many other fields, such as new energy automobiles, airplanes, military equipment, aviation, medical equipment, smart home, internet of things equipment and the like, and is also used for testing the flame retardant performance of many materials. The UL94 standard evaluates the flame retardant property class of materials by testing the vertical and horizontal combustion properties of the materials, thereby ensuring the safety properties of the materials in the event of fire. The sample needs to be pretreated when performing the combustion test, namely: the samples were placed in an environment at a temperature of 23±2 ℃ and a relative humidity of 50±5% for at least 48 hours to ensure consistent test conditions. In the prior test operation, the sample is usually placed in an incubator with a relatively small space.
