Abstract

Language: EN IEC 60689:2008 applies to measurements and test methods for tuning fork quartz crystal units in the range from 10 kHz to 200 kHz and standard values for frequency control and selection. This edition includes the following significant technical changes with respect to the previous edition: a) The title of the first edition is Measurements and test methods for 32 kHz quartz crystal units for wrist watches and standard values. The title is modified and the frequency range of this second edition is extended to the range from 10 kHz to 200 kHz. b) The Lissajous method is defined in the first edition as the standard measurement method. The PI network and bridge method are used in this second edition. c) The PI network has a transformer for impedance matching. This composition differs from that of IEC 60444-1.
