QML stands for Qualified Manufacturers List. It is a list of manufacturers and suppliers that have been qualified by the European Space Agency (ESA) to produce parts and components for ESA space missions.
To be included on the QML, manufacturers and suppliers must meet strict requirements for quality, reliability, and environmental compliance. They must also demonstrate the ability to produce components that meet the demanding performance, safety, and environmental requirements of space missions.
The QML is an important tool for ESA, as it helps the agency to ensure that it is working with suppliers that meet its high standards for quality and reliability. It also helps ESA to streamline the procurement process, by providing a list of qualified suppliers that can be easily accessed by procurement staff.
Overall, the QML is an important part of ESA's efforts to ensure the success of its space missions and to promote excellence in the aerospace industry.
