16、any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non-governmental organizations liaising with the IEC also participate in this preparation. The IEC collaborates closely with the international Organization for St
17、andardization (ISO) in accordance with conditions determined by agreement between the two organizations: 2) The formal decisions or agreements of the IEC on technical matters, prepared by technical committees on which all the National Committees having a special interest therein are represented, exp

19、 promote international unification, IEC National Committees undertake to apply IEC International Standards transparently to the maximum extent possible in their national and regional standards. Any divergence between the IEC Standard and the corresponding national or regionai standard shall be clear
20、ly indicated in the latter. International Standard IEC 444-5 has been prepared by IEC technical committee 49: Piezoelectric and dielectric devices for frequency control and selection. It forms Part 5 of a series of publications dealing with the measurements of piezoelectric quartz crystal unit param

Part 2: Phase offset method for measurement of motional capacitance of quartz crystal units, is issued as IEC 444-2.
22、 Part 3: Basic method for the measurement of two-terminal parameters of quartz crystal units up to 200 MHz by phase technique in a n-nework with compensation of parallel capacitance Co, is issued as IEC 444-3. Part 4: Method for the measurement of the load resonance frequency ffi load resonance resi
