Inspect the crimping dimension in the die-set area as indicated in the picture. Take four measurements across the crimped ferrule at 45° to each other using a vernier calipers in the middle section of the crimped length of the ferrule. Verify that all four measurements are according to the designated crimping diameter. Tolerance 0/-0,2 mm. Step 2. Inspect the crimp taper values Measure the diameter at the top of the ferrule and at the bottom of the ferrule (see picture) Verify that the ferrule taper satisfies the following limits: Taper ≤ 0,3 mm. for hose size up to and including 5/8 inch Taper ≤ 0,6 mm. for hose size from 3/4 inch up to and including 3 inch Marketing/bvs/28.05.2021
