The safety of industrial operators depends largely on the ability of guards (whether metal 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 tests.<\/p>\n\n

At our laboratory<\/a>, we perform impact tests using the pendulum method, a rigorous procedure that simulates the collision of a body against the protective structure.<\/p>\n\n

<\/div>\n\n

WHAT THE PENDULUM TEST INVOLVES<\/h3>\n\n

The test aims to verify the mechanical strength of the panel and its fastening systems (uprights, clips, screws). The test consists of dropping an impact body (the pendulum) from a predetermined height, causing it to collide with the center of the shelter or at the points considered most critical.<\/p>\n\n

Based on regulations and customer specifications, we use different types of impact to simulate real-life scenarios.<\/p>\n\n

Soft Body Test (Human Impact Simulation)<\/p>\n\n\n\n

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

Objective: To 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 hazardous area.<\/p>\n<\/div><\/div>\n\n

Test with \u201cHard\u201d Body (Simulation of object projection)<\/p>\n\n\n\n

The test is performed with a rigid metal weight. This impact body simulates the projection of a mechanical component or workpiece that detaches from the machine.<\/p>\n\n\n\n

Structural strength: The test shows whether the panel material (e.g., a polymer) tends to crack or whether the restraint systems fail under impulse loading.<\/p>\n\n\n\n

Multiple impacts: Tests can be repeated to test the fatigue of the material.<\/p>\n<\/div><\/div>\n\n
