Introduction

GB/T 22317 "Piezoelectric Filters with Quality Assessment" aims to provide general requirements and quality assessment procedures for piezoelectric filters. It is planned to be

It consists of the following 6 parts.

Part 1.General specifications. The purpose is to specify the terms and definitions of piezoelectric filters, as well as the general requirements for quality assessment procedures.

Part 2-1.Quartz Crystal Filter Usage Guide. The purpose is to give the types, structures and general principles of quartz crystal filters.

Therefore, it provides guidance for users to reasonably select quartz crystal filters and meet their usage needs.

Part 2-2.Guidelines for the use of piezoelectric ceramics. The purpose is to give the type, structure and general principles of piezoelectric ceramic filters, so as to provide

Provide guidance for users to choose piezoelectric ceramic filters appropriately and meet their usage needs.

Part 3.Standard shape and terminal connections. The purpose is to give the commonly used appearance diagrams and terminal functions of quartz crystal oscillators.

definition.

Part 4.Sub-standard capability approval. The purpose is to give priority and applicable requirements for piezoelectric filters based on capability approval.

Measurement methods and give the general performance requirements adopted in the detailed specifications.

Part 4-1.Blank Detailed Specification Capability Approval. The purpose is to give detailed specifications for piezoelectric filters based on capability approval

format and minimum content requirements.

The blank detailed specification is a supplementary document to the sub-specification and contains the minimum content requirements of the detailed specification.

The following detailed specification home page format is only applicable to standard product piezoelectric filters.

For customized piezoelectric filters, if there is no plan to publish detailed specifications, it is recommended to use the home page format in Appendix A. This format is not mandatory

Sexual, but recommended to be followed whenever possible.

For the numbers in square brackets in the home page format, it is advisable to fill in the following corresponding items in the corresponding positions.

[1] The national standardization authority that issues detailed specifications according to its authority. Where applicable, obtain detailed specifications from the department.

[2] IEC Q number and assigned detail specification number.

[3] The number and version number of the relevant IEC general specification or sub-standard, if there is any difference, plus the relevant information of the national standard.

[4] The country number, publication date of the detailed specification that is different from the IEC Q number, as well as other content required by the national standard and any

Revision number.

[5] A brief description of the piezoelectric filter or range of piezoelectric filters (e.g., center frequency and filter type).

[6] Information on typical structures (when applicable) (such as resistance welding, cold pressure welding).

For [5] and [6], the detailed specification should give the complete content required by IEC QC001005 and IEC QC001004.

[7] Outline drawings marked with main interchangeable dimensions, in compliance with IEC 60368-3 and/or in compliance with corresponding national or international standard documents
