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.
