Description

Technical Field

[0001] This utility model relates to the field of fire safety helmet testing, and in particular to a fire safety helmet testing device. Background Technology

[0002] The main purpose of aging tests is to simulate the aging process of fire safety helmets under long-term use or harsh environments, and to evaluate whether their performance can meet the requirements for continuous protection of the wearer. Through testing, the durability, stability, and performance under different conditions of fire safety helmets can be understood. Aging tests include ultraviolet aging tests and thermal aging tests. Ultraviolet aging tests use an ultraviolet aging test chamber to irradiate the fire safety helmet, while thermal aging tests place the fire safety helmet in a high-temperature environment to simulate high-temperature working scenarios. Traditional fire safety helmet testing equipment can only meet one of the ultraviolet aging tests or thermal aging tests, and the test items are limited, so there is an urgent need to improve it.
