Foreword

GB/T 12274 "assessed quality quartz crystal oscillator" is divided into the following sections. --- Part 1. Generic specification; --- Part 2. Guide; --- Part 3. Sectional specification - Capability approval; --- Part 3-1. Blank detail specification - Capability approval; --- Part 4. Sectional specification - Qualification approval; --- Part 4-1. Blank detail specification - Qualification approval. This is Part 1 GB/T 12274 in. Rules in this section in accordance with GB/T 1.1-2009 given draft. This Part replaces GB 12274-1990 "assessed quality quartz crystal oscillators - Part 1. Generic specification", and GB 12274- Compared to 1990, the main changes are as follows. --- Increased 34 terms and definitions; --- According to the general provisions of electronic components quality certification, a comprehensive quality assessment provisions of the rules of procedure; --- Increased by 25 electrical properties measurements, nine mechanical and environmental test items, test methods for durability; --- Added Appendix A, Appendix B, Appendix C and Appendix D. This section uses redrafted law revision adopts IEC 60679-1.2007 "quartz crystal oscillators - Part 1. Generic specification." This portion of IEC 60679-1.2007 technical differences exist compared to the terms of these differences has been involved through its outer margins Vertical single-line position (|) was indicated in Appendix D gives the corresponding list of technical differences and their reasons. This section also made the following editorial changes. --- Normative References 3.2.39 and removed ANSIT1.105.03, ANSIT1.101, TelcordiaGR-253 and ETSIEN300462. --- Chapter 2 raised to the "Priority" in Chapter 3. Location --- straight lines in FIG. 2 are offset, and is corrected to the correct location. --- 8 Videos complement the top-right jitter tolerance line f3 ~ f4 segment. --- 5.5.22.4 "AM frequency response" is calculated on the total distortion to 5.5.22.3 "amplitude distortion" in the. --- Metric instead of imperial Wire Gauge. --- This section with environmental testing of national standards GB/T 2423 instead of the corresponding IEC 60068, they are unskilled in reference to this part of the Surgery difference. This part is proposed by the Ministry of Industry and Information Technology of the People's Republic of China. This part of the frequency control and selection by the National Focal piezoelectric Standardization Technical Committee (SAC/TC182) devices. This section drafted by. China Electronic Components Industry Association Branch of the piezoelectric crystal, China Electronics Standardization Institute. The main drafters of this section. Zhang Yi, Jiang Liansheng, T..
