The IPC is conducted as soon as the manufacturer has started production and has 50 – 100 pieces completed and ready for packing. The purpose of the IPC is to determine if the initial batch of products produced by the manufacturer complies with the clientâ€™s specifications. If at this stage, any deviation beyond established tolerance is noticed, timely corrections are made, before bulk production begins. A written inspection report is prepared, confirming observations and a copy is given to the manufacturer. If required a copy can also be sent to the customer.
