Drop ball test for Basic Impact safety lenses: a ONE inch steel ball dropped from a height of 50 inches. High Velocity Impact test for High Impact lenses: a 1/4 inch steel ball hitting the lens at 150 feet/sec. The steel ball drop test is commonly used in product development to test the durability and impact resistance of materials. It can help engineers and designers determine the strength of a material and make necessary improvements to ensure its reliability and safety in real-world applications. 5. Are there any safety precautions to consider when . Pick up a steel ball by sticking it to a freshly washed finger and drop it into the capillary tube. This works better than using forceps. When dropped into the capillary, the tiny ball is usually stuck at the air-liquid interface. Use a magnet to move the steel ball below the meniscus and to a desired position inside the test solution.
