The safety of industrial operators largely depends on the ability of guards (whether wire mesh, polycarbonate panels, or safety glass) to withstand accidental impacts. To ensure that a protective barrier complies with current regulations, it is essential to subject it to dynamic resistance testing.<\/p>\n\n

At our laboratory, we perform impact tests using the pendulum method\u2014a rigorous procedure that simulates an object colliding with the protective structure.<\/p><\/p>\n\n

<\/div>\n\n

THE PENDULUM TEST: WHAT IS IT ABOUT?<\/strong><\/h3>\n\n

The test aims to verify the mechanical resistance of the panel and its fastening systems (posts, clips, screws). The procedure consists of dropping an impact body (the pendulum) from a predetermined height, causing it to strike the center of the guard or the areas identified as most critical.<\/p>\n\n

Based on relevant standards and customer specifications, we use different types of impactors to simulate real-world scenarios.<\/p>\n\n

SOFT-BODY IMPACT TEST (HUMAN IMPACT SIMULATION)<\/strong><\/h3>\n\n

A large flexible bag is used to simulate an operator accidentally falling against the guard.<\/p>\n\n

Objective:<\/strong> Verify that the guard does not detach and that deformation does not allow the body to pass through the barrier or come into contact with the hazard zone.<\/p><\/p>\n\n

HARD-BODY IMPACT TEST (PROJECTED OBJECT SIMULATION)<\/strong><\/h3>\n\n

The test is performed using a rigid metallic mass. This impact body simulates a mechanical component or workpiece being projected after detaching from the machinery.<\/p>\n\n

Structural resistance:<\/strong> The test highlights whether the panel material (for example, a polymer) tends to crack or if the retention systems fail under the impulsive load.<\/p>\n\n

Multiple impacts: <\/b>Tests can be repeated to evaluate material fatigue.<\/p>
