Foreword
The guidance of technical documents instead of GB/T 10962-1989 "General principles of reliability of machine tools," the guidance of technical documents and GB/T
10962-1989 Compared to the main changes are as follows.
--- "1 Scope" in the clear technical documents for the guidance of this machine contactor relays, machine contactors, machine tools
Travel switches, machine tools and other buttons with the contacts of the machine electrical components;
--- The original standard "4 classification and characteristic parameters" and "5 technical requirements" to "4 reliability index";
--- The original standard test method No. 6 to 5, delete the original standard test method has nothing to do with the reliability of the contents of the test added
Product testing and failure criteria and so on;
--- Remove the original standard and reliability has nothing to do with the "7 Inspection Rules" and "8 manufacturers to provide documents and information" and "Appendix A"
And other content, an increase of "6 reliability verification test program and test procedures" and "7 test records and test reports" and so on.
Appendix A of this Guidance Document is an informative annex.
This guidance document is proposed by China Electrical Equipment Industry Association.
The guidance of technical documents by the National Standardization Technical Committee of low-voltage electrical (SAC/TC189) centralized.
This Guidance Document is drafted by. Hebei University of Technology, Shanghai Electric Apparatus Research Institute (Group) Co., Ltd.
The main drafters of this technical guidance document. Lu Jianguo, Ji Hui Yu, Suxiu Ping, Chen Xiaodong.
This Guidance Technical Document replaces the standards previously issued as follows.
--- GB/T 10962-1989.
General principles of machine tool electrical reliability
1 Scope
This Guidance Document specifies the reliability requirements for machine tool electrical components (referred to as machine tools) and the general requirements for reliability verification tests
Summation methods, including the reliability level of machine tool electrical components, test methods, reliability verification test programs and test procedures.
This guideline is applicable to contactors relays for machine tools, contactors for machine tools, stroke switches for machine tools, buttons for machine tools, etc.
Machine electrical components with contact, but also for machine tools with other micro-switches and other electrical contact with the electrical components for reliability verification test
Inspection reference use.
