Title Synthetic quartz crystal - Specifications and guidelines for use
Project Number 21390
Abstract/Scope IEC 60758:2008(E) applies to synthetic quartz single crystals intended for manufacturing piezoelectric elements for frequency control and selection. This fourth edition cancels and replaces the third edition, published in 2004. This edition constitutes a technical revision. It includes the following significant technical changes with respect to the previous edition: preparation of AT-cut slice sample for etching is changed to make it easier; etch channel grade classification is changed considering request of the user and explanation of quartz axes difference between IEEE and IEC is added as Annex F.

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of withdrawal (dow) latest date by which national standards conflicting with an EN (and HD for CENELEC) have to be withdrawn

(6) This list of normative references is purely indicative. The only official list of normative reference is the list of the published standard.
