vakuumtetsprov

Vakuumtestprov, often shortened to vakuumtest, is a method used to assess the airtightness of a component or system. It involves creating a vacuum on one side of the item being tested and then measuring the rate at which air leaks in. This technique is crucial in various industries, including manufacturing, aerospace, and medical device production, to ensure product integrity and safety.

The process typically starts by sealing the object or a section of it and then connecting it to a vacuum pump. The pump reduces the pressure within the sealed volume. Sensitive pressure sensors are then used to monitor any increase in pressure over a specified time. A significant pressure rise indicates a leak. The rate of pressure increase can be used to quantify the leak rate, often expressed in units like Pascal cubic meters per second (Pa m³/s) or standard cubic centimeters per minute (sccm).

Different types of vakuumtestprov exist, including gross leak testing, which detects larger leaks, and fine leak testing, which identifies very small leaks. The specific method and equipment employed depend on the size and sensitivity of the item being tested and the required level of airtightness. Calibration of the test equipment is essential to ensure accurate and reliable results. Vakuumtestprov is a non-destructive testing method, meaning the item being tested is not damaged during the process.
