Impact Testing of Horse-Riding Equipment for Equestrian Sports
Falling from heights can cause major fracturing and bruising; falling from a horse is no different. A rider falling from a stationary horse hits the ground at roughly 6 m/s, equivalent to 1.26kJ for a 70kg rider. This is considerably worsened when moving- the rider can have a horizontal velocity of up to 12 m/s, in addition to the 6 m/s vertical velocity. It's not just the fall itself that creates a problem, injuries can be caused by collision with the hooves of the horse and the accessories of the course (poles, fencing etc).
Protective equipment is available for riders but must be thoroughly tested in order to provide sufficient peace of mind and protection to participants, event organizers and manufacturers. Our CEAST drop-towers allow the manufacturer to test their products to stringent international standards. Standards such as BS EN 13158:2009 provide test conditions designed to accurately replicate and measure the response of protected body parts to the simulated fall from a horse. The test is performed by dropping a guided, custom striker onto a bespoke anvil, onto which the protective equipment is placed. The standard specifies exactly how large the sample size should be, what parts should be tested, and how. A succesful product attenuates the force transmission within a defined safe range. We can also perform the penetration test of equestrian helmets in accordance with BS EN 1384:2012, whereby a conical striker with a defined mass is dropped onto the helmet with a pre-determined velocity. Failure occurs if the cone penetrates the helmet.
CEAST 9350 supplies all the energy required by the standard, together with the accuracy and repeatability required for obtaining professional, meaningful results. The versatility of the Instron product range means that standard and specialized fixtures can easily be fitted and replaced for various testing types; and embedded transducers can detect force from the specimen's perspective, which is particularly useful in this situation. Often, as in this case, unusual or uncommon standards can be met by our standard testing machines, simply with the inclusion of a specially-designed custom part. Additionally, our DAS (Data Acquisition System) can easily be configured to collect data from such customized, additional sensors.

Impact resistance is one of the most important properties for component designers to consider, as well as the most difficult to quantify. Impact resistance is a critical measure of service life and more importantly these days, it involves the perplexing problem of product safety and liability. With the combined experience of Dynatup® and CEAST, Instron® has more than 80 years experience in designing impact testing systems to simulate real-life impact conditions.

The new CEAST DAS 64K is a state-of-the-art Data Acquisition System designed for impact testing instruments. Compatible with the full range of CEAST impact testing systems, including pendulum type machines (CEAST 9000 Series) and drop towers (CEAST 9300 Series), it’s the key for instrumented impact testing. The DAS 64K also enables the data collection from instrumented tups or hammers on older models and non-CEAST impact machines.
