An inspection is, most generally, an organized examination or formal evaluation exercise. In engineering activities inspection involves the measurements, tests, and gauges applied to certain characteristics in regard to an object or activity. The results are usually compared to specified requirements and standards for determining whether the item or activity is in line with these targets. Inspections are usually non-destructive.

A 2007 Scottish Government review of scrutiny of public services (the Crear Review, 2007^[1][2]) defined inspection of public services as '...periodic, targeted scrutiny of specific services, to check whether they are meeting national and local performance standards, legislative and professional requirements, and the needs of service users.'

A surprise inspection tends to have different results than an announced inspection. Leaders wanting to know how others in their organization perform can drop in without warning, to see directly what happens. If an inspection is made known in advance, it can give people a chance to cover up or to fix mistakes. This could lead to distorted and inaccurate findings. A surprise inspection, therefore, gives inspectors a better picture of the typical state of the inspected object or process than an announced inspection. It also enhances external confidence in the inspection process. See section 4.12 of the Crear report.^[1]

  Specific instances

  Business

In international trade several destination countries require Pre-shipment inspection. The importer instructs the shipper which inspection company should be used. The inspector makes pictures and a report to certify that the goods that are being shipped and produced are in accordance with the accompanying documents.

  Government

In government and politics, an inspection is the act of a monitoring authority administering an official review of various criteria (such as documents, facilities, records, and any other assets) that are deemed by the authority to be related to the inspection. Inspections are used for the purpose of determining if a body is complying with regulations. The inspector examines the criteria and talks with involved individuals. A report and evaluation follows such visits.

The Food Safety Inspection Service is charged with ensuring that all meat and egg products in the United States are safe to consume and accurately labeled. The Meat Inspection Act of 1906 authorized the Secretary of Agriculture to order meat inspections and condemn any found unfit for human consumption. The United Nations Monitoring, Verification and Inspection Commission is a regulatory body that inspects for weapons of mass destruction. The Scottish Commission for the Regulation of Care regulates and inspects care services in Scotland.

  Road vehicles

A vehicle inspection, e.g., an annual inspection, is a necessary inspection required on vehicles to conform with laws regarding safety, emissions, or both. It consists of an examination of a vehicle's components, usually done by a certified mechanic. Vehicles pass a pre-warranty inspection, if, and only if, a mechanic provide evidence for the proper working condition of the vehicle systems specified in the type of inspection.

  Engineering, mechanics

Quality related inspection is an essential part of quality control.

A mechanical inspection is usually undertaken to ensure the safety or reliability of structures or machinery.

In Europe bodies involved in engineering inspection may be assessed by acreditation bodies according to ISO 17020 "General criteria for the operation of various types of bodies performing inspection". This standard defines inspection as Examination of a product design, product, service, process or plant, and determination of their conformity with specific requirements or, on the basis of professional judgement, general requirements.

Non-Destructive Examination (NDE)^[2] or nondestructive testing (NDT) describe a number of technologies used to analyze materials for either inherent flaws (such as fractures or cracks), or damage from use.

Some common methods are visual, microscopy, Liquid or dye penetrant inspection, magnetic-particle inspection, X-ray or radiographic testing, ultrasonic testing, eddy-current testing, acoustic emission testing, and thermographic inspection. In addition, many non-destructive inspections can be performed by a precision scale, or when in motion, a checkweigher. Stereo microscopes are often used for examining small products like circuit boards for product defects.

  Medical

An medical inspection is the thorough and unhurried visualization of a client, this requires the use of the naked eye.

  Military

An examination vessel is a craft used to inspect ships entering or leaving a port.
