We use a duplicate of the impact testing machine that measures armor for the CE standard compliance. A transducer on the testing machine measures the amount of force transferred through a pad at impact. The higher the number, the more force is transferred. Lower transferred force means that the pad better disperses the force of the impact, before it can reach your body. The chart below displays a series of test results comparing TF Pad impact absorption with other types.
Aerostich Suits and Jackets comes with TF energy absorbing material. This viscoelastic material is unique because the faster and harder it is struck, themore it will resist impact. Its remarkable characteristic of stiffening in high-speed impacts yet remaining soft and moldable for comfort make it the perfect choice for protective, comfortable body armor.
TF PAD PERFORMANCE
TF is sensitive to temperature, and each pad is optimized for specific temperature ranges. Fortunately, your body warmth and the microclimate inside your riding suit or jacket keeps the pads within the most desirable range. If you TF pads exposed to freezing temperatures, they become stiff and may split if flexed sharply. Such accidental damage can be repaired using any brand of contact cement.
*Test data based on results from Aerostich impact testing, series number 211108-RH, performed Nov. 2008. Measures indicate materials resilience to impact as a reading of kilonewtons (kN). A kilonewton is an SI (International System of Units) measurement equal to 1000 Newtons; A Newton is defined as the force required to accelerate a mass of 1 kilogram at the rate of 1 meter per second. 1 kN = 224 lbs. Testing sensors measure the amount of force transferred through the pad at impact. Lower kN readings indicate greater overall energy absorption and better impact dampening ability. The average (mean) of multiple impacts: TF2=28.71kN, TF3=25.83kN, TF4=19.83kN, TF5=19.11kN
'NOT CE APPROVED' LABELS
TF 2-4 pads were developed years before CE standards existed to provide effective protection when fitted into our Roadcrafter and Darien Suits. When we introduced TF armor, all protective garments, including road racing suits, featured sewn-in padding made from felt, foam rubber or other less effective materials. Roadcrafters were the first riders garments in the world to use removable armor pad systems, and to use an advanced energy absorbing material like TF. Our armor was tested at a CE lab in England and using a duplicate test apparatus there. The CE impact standards involve both energy absorption capability, and pad shape and size. Because of their shapes (not their energy absorption capabilities), Aerostich TF 2-4 pads do not match these European standards. In the hard-shelled areas, TF armor tested significantly better than most other CE approved armor. Around the softer edges, it tests lower.
INSTALLING TF PADS INTO NON-AEROSTICH GEAR
Additional adhesive backed sections of hook & loop are provided to allow you to install hip or back pads into any garment. Our experience has been that the adhesive will stay attached to lining fabrics for several years, but it also makes it simple to hand sew the hook & loop into place without opening the lining.
