Foreword

GB/T 12274 "Quartz Crystal Oscillator with Quality Assessment" is divided into the following parts.

---Part 1.General Specification;

---Part 2.Guidelines for use;

---Part 3.Standard shape and terminal connection;

---Part 4.Sub-standard ability approval;

---Part 4-1.Blank detailed specification capability approval;

---Part 5.Sub-specification appraisal and approval;
