The ISO 1720, Requirements for the operation of various types of bodies performing inspection specifies characteristic of these kinds of inspection agencies. Based on these requirements, these agencies must be impartial and independent in their inspection activities and in their inspection reports and results. All interested companies such as traders, buyers, sellers, engineering companies, construction companies must have access to the third party inspection services of these inspection companies. Impartial and independence conditions are very important factors for third party Inspection companies. In this direction, ISO17020 does not allow these companies to be participated or involved in any procurement, purchasing, construction, installation and even design activities. They must only provide third party inspection services and nothing else. Based definition of the ISO 17020,these inspection companies are category A inspection organization. Based on this standard, there are two more inspection organizations that are not independent. A category B inspection organization is an inspection department in a large scale company that is involved in the design, procurement, construction, installation, etc. and this inspection department provides third party inspection services to its own company. Usually a category B inspection organization is a quality control department in an engineering or EPC company. This department assists the company in procurement and purchasing projects and makes inspections on the equipment and materials that are purchased by its own company. Example for Third Party Inspection Services Company in Oil and Gas Industry. Suggest an EPC company has a contract with an oil company for design, procurement, and construction of a desalting plant. Then the quality control department of this EPC Company inspects on the equipment and material that have been ordered by EPC contractor for this desalting plant. So this is what we name second party inspection and based the ISO 17020 is category B type inspection. This inspection will not be enough by end user or in this example, an oil company. The oil company will hire an independent third party inspection company or in other words, a category A inspection company to conduct inspection on the procured equipment and material by EPC company. Sometimes the end user or oil company in this example decides not to hire an independent third party inspection company by itself but mandates that the EPC Company to hire an independent inspection agency that is in their approved list.
