A Qualified Product List (QPL) means a list of products, components, or materials that have been examined, tested, and have met all applicable standards or qualification requirements established by a certifying organization or government entity. QPL serves as a reference for organizations and industries seeking reliable and approved products or materials for their projects or operations without further documentation or testing. Typically, the QPL includes essential details such as product/material type, product identification, and test/qualification reference number. It also includes the name and plant address of the manufacturer and distributor, as applicable.

QPLs are typically created and maintained by certifying organizations, government agencies, or industry consortia. This is very often used for Space Qualified components, where NASA or ESA will publish a QPL that meet their specific criteria. These types of entities establish a stringent qualification processes and criteria that manufacturers must meet to have their products listed on the QPL. The qualification process often involves rigorous testing, inspections, audits, and documentation reviews to ensure that the listed products adhere to the specified requirements.

Organizations and industries or customers, procurement agencies, and other stakeholders often rely on QPLs to identify and select products (for use in critical applications or projects) that meet the applicable standards, streamlining the procurement and qualification processes.  QPLs provide assurance that the listed products have demonstrated the necessary quality, reliability, and performance characteristics demanded by the industry or specific standards. 

QPLs are commonly used in industries such as aerospace, defense, telecommunications, electronics, and other sectors, where product reliability & performance and adherence to strict standards are crucial. QPL minimizes risks and promotes consistency in product selection, ultimately contributing to the overall quality and reliability of projects and systems. It's important to note that different industries and organizations may have their own specific QPLs, tailored to their particular requirements and standards.
