These standards define a series of tests that ensure the safety and finish of a wheel. THESE TESTS ARE THE MINIMUM STANDARD USED TO DEFINE THE ENDURANCE OF FRPP WHEELS. Impact Testing: This test simulates a curb impact on the side of a tire\/wheel assembly. During testing, a tire\/wheel assembly is mounted at a 13-degree angle to a test fixture by the hub. A weight is dropped from 9 inches onto the assembly at the tire\/wheel intersection. The mass of the weight is determined by a formula, using the vehicle weight. Dynamic Cornering Fatigue Testing: This test simulates lateral loads applied to a wheel by the vehicle. During testing, a wheel is clamped to a fixture by the front face and a constant bending moment is applied through the hub. A wheel of new design will run a minimum of 1,000,000 cycles before approved. The load applied is determined by a formula, using the vehicle weight. Dynamic Radial Fatigue Testing: This test simulates axial loads applied to a wheel by the vehicle. During testing, a tire\/wheel assembly is mounted to an axle by the hub. A large drum drives the assembly while a load is applied perpendicular to the tire patch. A wheel of new design will run a minimum of 5,000,000 cycles. The load applied is determined by a formula, using the vehicle weight. Chrome Quality Testing: Copper-accelerated acetic acid-salt spray, commonly known as CASS testing, is the standard method used to test the corrosive performance of copper\/nickel\/chromium-plated wheels. The test is performed in a sealed chamber with a highly acetic spray directed onto the wheel for a predetermined amount of time, usually 66 hours.","brand":"Ford Performance Parts","offers":[{"title":"Default Title","offer_id":48183459086584,"sku":"BDXX_M-1007-P2085MB","price":360.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0725\/1538\/7640\/files\/M-1007-P2085MB.jpg?v=1775191774","url":"https:\/\/nadersautosupply.com\/products\/2015-2020-f-150-20-x-8-5-six-spoke-matte-black-wheel","provider":"Nader's Auto Supply","version":"1.0","type":"link"}
