Hohenstein and DuPont develop innovative tests for ballistic vests

BÖNNIGHEIM (msc) In cooperation with DuPont, the testing and research service provider Hohenstein has developed three innovative and reliable test methods for evaluating soft ballistic inserts. High wearing comfort of protective vests, such as bulletproof vests, and unrestricted mobility are crucial for the performance and endurance of police and military personnel. The new methods eliminate the discrepancy between existing tests and real body movements and positions.

An interdisciplinary team of experts from DuPont and Hohenstein developed the new test methods, which enable a precise evaluation of ergonomic comfort characteristics. "Our aim at Hohenstein is to reflect the real conditions of users as accurately as possible," explains Dr. Jan Beringer, Senior Scientific Expert at Hohenstein. "Targeted wearer tests were used to identify potential conflicts and movement restrictions. Based on decades of experience, tests and associated test devices and modules were then developed in close cooperation between DuPont and Hohenstein to simulate the wearing experience."

"To meet the urgent needs of police and military personnel, it is essential to maximize comfort and flexibility in soft ballistic solutions. The development of test methods to assess pain perception and movement restrictions is an important first step. By leveraging Hohenstein's recognized expertise in textiles and comfort, we can advance these solutions for the industry and improve comfort so that responders can perform their tasks more efficiently," added Christophe Djololian of DuPont.

Three comfort and mobility tests

• The Lower Costal Bending (LCB) test simulates the bending movement of the upper body. On duty, such movements lead to energy loss and faster exhaustion of the wearer. The LCB test quantifies the energy loss due to the stiffness of a ballistic protective vest.
• For maximum mobility, the ballistic protective clothing must adapt optimally to the wearer's body. The Double Curvature Compression (DCC) test replicates the shape of a curved torso and uses digital imaging to assess the adaptability and mobility of the protective clothing in the respective user situations.
• Where the edges of a ballistic vest meet the body - on the lower abdomen, neck or arm - the pressure can be uncomfortable. The Edge Pressure (EP) test simulates the pressure of the edges on the body and measures the resulting local pressure load.

The three test methods for evaluating the comfort and mobility of soft ballistic protective vests are now available from Hohenstein as a testing service. "We offer different solutions depending on the requirements," explains Dr. Jan Beringer. "Independent, certified tests can be carried out in the Hohenstein PPE laboratories using specially developed test equipment. The three test modules can also be purchased to make it easier for manufacturers of protective vests to develop products and assess the impact on end users."
