  • Page 25: Procedure Of A Tightness Test

    Test pressure Test pressure Duration of an automatic measurement The WAIO has a new evaluation algorithm which detects elastic deformation in watches and automatically compensates it. In the standard setting, the WAIO automatically determines the required measuring time for each measurement. The software continues the measurement until a meaningful result is obtained.

  • Page 26: Definitions

    Description Definitions Deformation measurement The measuring method of the WAIO is based on the principle of deformation. The watch is subjected to positive pressure to compress the watch housing, or a vacuum to expand it. The faster the deformation is compensated, the larger the leak in the watch case. The deformation of the case within a certain time serves as the basis for the measurement to determine whether the watch is leakproof or not.

  • Page 27: Reference To Standard Iso 22810

    • Elastic deformation of the test specimen; • Thermal influences. As the measuring time progresses, the measuring algorithm of the WAIO compensates for these influences and displays a more accurate result. This makes it more reliable and faster than an algorithm used for conventional deformation measurement.
