Designed and
tested to comply with all IWF standards, the new manufacturing process enables us to create a much cleaner lined plate, with a higher quality finish than previously. Each and every disc is
calibrated to within weight tolerances of no more than +/- 10 grams of stated weight. Drop tested from a height of 2500mm more than 30000 times! Every plate is calibrated to within the weight
tolerances as detailed below:
