A qualitative fit test, or QFT for short, is a type of non-destructive testing used to determine how well two objects fit together. In other words, it checks to see if the two objects are compatible and will not cause any leaks. This is an actual test before committing to a manufacturing process, as it can help you avoid costly mistakes.
What should I know about this?
The qualitative test measures the qualitative or non-quantitative features of a mating connection. It is typically done by measuring the size and shape of two objects and determining if they will fit together correctly. Additionally, these tests can be used to determine if there are any leaks in an existing connection. This is essential for quality assurance purposes before committing to total production. Quality fit tests help ensure that parts and components will function as intended when manufactured in large quantities. Manufacturers can save money and avoid costly mistakes down the road by taking the time to perform these tests during product development.
