1. General information
Aerotechnik Siegwart GmbH, Friedrichsthal commissioned us to inspect the aling characteristics of an airtight multi-leaf damper (class 4) in accordance with DIN EN 1751. The purpo of the test was to establish whether DIN EN 1751 requirements were met.
条件状语2. Description of inspected system
The description of the inspected damper in accordance with the manufacturer’s specifications is included in enclosure 1. The documents prented to us do not contain production tolerances.
3. Test structure and realisation of measurements
The test station structure is illustrated in the enclosure. A diaphragm gas meter was utilid to measure air volume and a differential pressure measuring instrument (SI) to measure the pressure. 4. Measuring results
Measuring results are listed in Table 1 of the report.
The leaked air volumes measured are less than values specified in DIN EN 1751 (as illustrated in Table 1).
The inspection described here was not intended as a type or design acceptance test, endurance test, material test or production inspection, and no requirement for such existed. The measurement results are only valid for the inspected damper.
