Annotation of standard text IEC/TR 60444-4-ed.1.0 :

Specifies a simple method of measuring load resonance frequency. The method uses the change in resonance frequency which occurs when a load capacitance is inserted in series with the crystal unit. Definit une methode simple de mesure de la frequence de resonance. Elle utilise le changement de la frequence de resonance qui a lieu lorsquune capacite de charge est inseree en serie avec le resonateur a quartz. Cette publication a le statut dun rapport technique.
