The purpose of an Inspection and Test Plan (ITP) is assemble documentation that records all inspection and testing requirements relevant to a specific process or area. An Inspection and Test Plan identifies the items of materials and work items requiring inspection and/or tested, the inspection parties and frequency of the inspections, as well as Hold and Witness Points.
The ITP will include references to relevant standards, acceptance criteria and the records to be maintained. Inspection and Test Plans, when properly implemented, help ensure through verification that work has been performed to the required specification, standard, site requirements, and sutiable documentation has been collected.
