Title Measurement and test methods for tuning fork quartz crystal units in the range from 10 kHz to 200 kHz and standard values
Project Number 21475
Abstract/Scope IEC 60689:2008(E) 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 second edition cancels and replaces the first edition published in 1980. This edition constitutes a technical revision. It 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.

(1) Date of ratification (dor) date when the Technical Board notes the approval of an EN (and HD for CENELEC), from which time the standard may be said to be approved


(2) Date of availability (dav) date when the definitive text in the official language versions of an approved CEN/CENELEC publication is distributed by the Central Secretariat


(3) Date of announcement (doa) latest date by which the existence of an EN (and HD for CENELEC), a TS or a CWA has to be announced at national level


(4) Date of publication (dop) latest date by which an EN has to be implemented at national level by publication of an identical national standard or by endorsement


(5) Date of withdrawal (dow) latest date by which national standards conflicting with an EN (and HD for CENELEC) have to be withdrawn
