Introduction

GB/T 12274 "Quartz Crystal Oscillators with Quality Assessment" aims to provide general requirements and quality assessment for quartz crystal oscillators

The program is planned to consist of 7 parts.

---Part 1.General specifications. The purpose is to specify the terms and definitions of quartz crystal oscillators, as well as the general quality assessment procedures.

Require.

---Part 2.User Guide. The purpose is to give the type, structure and general principles of quartz crystal oscillators, so as to provide users with

Provide guidance on rationally selecting oscillators and meeting usage requirements.

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

Functional definition.

---Part 4.Sub-standard capability approval. The purpose is to give priority values for quartz crystal oscillators based on capability approval

and applicable measurement methods, and give the general performance requirements adopted in the detailed specifications.

---Part 4-1.Blank detailed specification for capability approval. The aim is to give quartz crystal oscillators based on capability approval

Detailed specification of format and minimum content requirements.

---Part 5.Sub-standard appraisal and approval. The purpose is to give priority values for quartz crystal oscillators based on qualification approval

and applicable measurement methods, and give the general performance requirements adopted in the detailed specifications.

---Part 5-1.Blank detailed specification appraisal approval. The purpose is to give quartz crystal oscillators based on qualification approval

Detailed specification of format and minimum content requirements.

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

For customized quartz crystal oscillators, if there is no plan to publish detailed specifications, it is recommended to adopt the homepage format of Appendix A. This format is not

It cannot be modified, but is recommended to be followed whenever possible.

For the numbers in square brackets in the following table, it is recommended to fill in the following corresponding items in the corresponding positions.

[1] The name of the national standards authority that issues detailed specifications under its authority. Where applicable, obtain detailed specifications from the department.

[2] IEC Q number and detailed specification number assigned by IEC.

[3] General specification and related sub-standard numbers and their version numbers. If there are differences, relevant information about national standards can also be added.

[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
