Inspection and Test Plan (ITP)
Definition - What does Inspection and Test Plan (ITP) mean?
An inspection and test plan, or inspection test plan, is a document or series of documents used for quality assurance purposes. An inspection and test plan outlines how the quality of a particular object will be ensured both at its beginning and throughout its service life.
Corrosionpedia explains Inspection and Test Plan (ITP)
An inspection and test plan will highlight many different testing and inspection tasks. For instance, destructive testing of materials may be done during the initial construction phase of the project to ensure that the materials have adequate properties and that the employees working with the materials have the required skill level for the project. Once the service life has begun, nondestructive methods are primarily used.
The inspection methods include ultrasonic testing, radiographic testing, visual inspection, pH testing and many others. The timing and frequency of these inspections are determined in the inspection and test plan. The plan will also set up intervals of auditing to make sure that the necessary inspections have been performed and are sufficiently documented.
An inspection and test plan is used in a variety of industries, especially the construction industry. Bridges, buildings and roads must be periodically inspected and tested to ensure that they are safe for their users or inhabitants. Another sector that uses inspection and test plans frequently is the oil and gas industry. Pipelines, for example, can be subject to corrosion because of the contents they carry. An inspection and test plan will dictate how often inspections will be conducted to prevent a pipeline failure. Although less common, service industries can also undergo inspection and test plans; these are usually more audit-focused and rely less on mechanical inspection methods. These audits are aimed at making sure the service operation is achieving its quality goals.
