Notice: 1. The cumulative tolerance of 10 sprocket hole pitch is ±0.2mm.

2. Carrier camber shall be not more than 1mm per 100mm through a length of 250mm.

3. A & B measured 0.3mm from the bottom of the packet.

4. t measured at a point on the inside bottom of the packet to the top surface of the carrier.

5. Pocket position relative to sprocket hole is measured as the true position of the pocket and not the pocket hole.
