Goggles Puncture Resistance Testing Machine

The safety goggle puncture resistance testing machine is a device used to test the puncture resistance of safety goggles against impact from sharp objects.

Application

It is to make a certain weight of sharp objects fall from the height specified in the standard and act on the surface of helmet or goggles, so as to determine the ability of helmet or goggles to resist penetration by sharp objects.

Standards

GB 811-2010: Helmets for motorcyclists

ECE R22.05: Uniform Provisions Concerning the Approval of Protective Helmets and Their Visors for Drivers and Passengers of Motor Cycles and Mopeds

EN1077: Helmets for alpine skiing and snowboarding

Parameters

Accessoriess

Perforator (puncture cone)

Drop hammer (impact hammer)

Head fixation device (head mold support)

Guide tube

Electromagnetic release device, etc.

Test Procedures

Sample and Equipment Inspection: Confirm that the goggles to be tested are free of manufacturing defects and are properly installed on the corresponding size safety helmet/headgear according to the standard.

Parameter Setting: Select a matching head form, fix the helmet onto the head form, ensuring the goggles are at a natural wearing angle without extra stretching or compression.

Positioning the Punch: Manually adjust the punch position so that it is vertically aligned with the center area of the goggles, and the bottom of the punch is in contact with the surface of the goggles, leaving a space of at least 5mm above the head form.

Performing the Impact Test: Using a manual pull-type or automatic release device, allow the falling weight to drop freely from a set height, impacting the top of the punch, and transferring the impact force to the goggles through the punch.

Data Recording: Record data at the moment of impact using a high-speed camera or pressure sensor, such as the peak impact force and the deformation of the goggles, for subsequent analysis.
