What is the difference between ITP and fat? - in instrumentation project engineering.
The testing protocols FAT (Factory Acceptance Test) and ITP (Inspection and Test Plan) function similarly but carry unique objectives during quality control and testing operations.
Key Differences the FAT (Factory Acceptance Test) & ITP (Inspection and Test Plan)
| Feature | FAT (Factory Acceptance Test) | ITP (Inspection and Test Plan) |
|---|---|---|
| Definition | A manufacturer-operated testing procedure takes place in their plant to confirm that shipped goods match their contract requirements and operational requirements. | The inspection and testing activities precisely outline the production and installation process in this systematic document format. |
| Purpose | Testing of products or systems must demonstrate correct functionality until the point of customer delivery. | This document offers direction for testing and quality control inspections that take place across repeated production phases and commissioning operations. |
| Scope | Factory testing is directed at complete machines before their factory departure. | Every manufacturing step requires testing through inspections starting from raw materials and continuing to process checks and ending with acceptance testing. |
| Execution Stage | The quality control process starts immediately after production finishes yet before product delivery to customers. | The testing procedures extend across the whole production cycle from the initial raw materials up to the end acceptance phase. |
| Participants | Manufacturers join clients and external inspection entities to participate in this process. | Quality control teams together with engineers and suppliers execute tests while clients may participate. |
| Outcome | The successful completion of tests leads to creation of a FAT report that validates both test results and product specifications compliance status. | A documented strategy guides the execution of quality control procedures while creating complete documentation records. |
Relationship Between FAT and ITP
- The Inspection Test Plan (ITP) mandates the inclusion of FAT as one of its procedures.
- Within ITP occurs the specific testing operation FAT which comprises a separate section.
- FAT performs pre-shipment validation while ITP provides oversight for all the stages of product quality control.
