Fire mask resistance to high-speed particle impact testing machine

Fire mask resistance to high-speed particle impact testing machine is a device used to test the impact resistance of fire masks. It simulates the real working environment of the mask under the impact of high-speed particles to ensure that the mask has sufficient protective capabilities. The following is some relevant information about the fire mask resistance high-speed particle impact testing machine:

 

working principle:

Fire mask resistance to high-speed particle impact testing machine usually includes a transmitting device and a receiving device. The launching device can launch high-speed particles (usually metal or plastic balls) to impact the mask sample at a fixed speed and angle. The receiving device is used to measure the performance parameters of the mask sample after impact, such as the degree of deformation, whether it is broken, etc.

 

Test process:

Before testing, the test parameters must first be set according to relevant standards and specifications, including impact speed, impact angle, etc. Then, fix the fire mask to be tested on the test fixture and ensure that the mask is worn normally. After the test starts, the launching device will launch high-speed particles at a set speed and angle to impact the mask sample. The receiving device will record the performance data of the mask after the impact, such as the strength and deformation of the mask.

 

Evaluation indicators:

The fire mask resistance to high-speed particle impact test mainly evaluates the following performance indicators of the mask:

1. Light transmittance: After the test, the field of view of the mask should remain clear and transparent without obvious breakage or distortion.

2. Strength: The mask should remain intact after impact and should not break or crack.

3. Degree of deformation: The mask may deform to a certain extent after being impacted, but it cannot exceed the specified limit.

 

Standard specifications:

Fire mask resistance to high-velocity particle impact testing is usually conducted based on specific international standards, such as EN 166 (European standard) or ANSI Z87.1 (American standard). These standards will specify test parameters, evaluation indicators, and qualification requirements for test results.

 

Summarize:

The fire mask's high-speed particle impact resistance test machine can be used to evaluate the impact resistance of fire masks to ensure that the mask can effectively protect users from high-speed particles in real environments. The use of this kind of testing machine helps to verify the quality and performance of fire masks and improve the safety and protection of operators.
