Foreword

GB/T 2900 "Electrical terminology" consists of many parts. This part is part 99 of GB/T 2900. This part is drafted in accordance with the rules given in GB/T 1.1-2009. This part of the part of the GB/T 2900.13-2008 "electrical terminology credibility and service quality", compared to the main technical changes as follows. --- instead of GB/T 2900.13-2008 in the 2.1 ~ 2.18 related content; --- not included in the quality of telecommunications services (2.19 ~ 2.20), power system quality of service (2.21 ~ 2.30) and the quality of service related to the content. This part uses the translation method equivalent to IEC 60050-192..2015 "International Electrotechnical Vocabulary Part 192. Credibility". The term entry numbers in this section are consistent with IEC 60050-192..2015 and differ from IEC 60050-192..2015 as follows. --- Removes the contents of Chapter 1 that do not apply to "scope". This part is presented by the National Electrotechnical Standardization Technical Committee (SAC/TC232). This part of the National Electrotechnical Electronics Reliability and Maintenance Standardization Technical Committee (SAC/TC24) and the national electrical terminology standardization Technical Committee (SAC/TC232). This part of the drafting unit. Ministry of Industry and Information Technology Electronics Fifth Institute, in the machine productivity promotion center. The main drafters of this part. Kong Xuedong, Ji Chunyang, Yu Min, Yang Chunhui, Pan Yong, Kuang Zhili, Li Guifang. This part of the part of the replacement GB/T 2900.13-2008. The previous releases of GB/T 2900.13-2008 are. --- GB/T 14733.3-1993; --- GB/T 3187-1994. Electrotechnical terminology credibility

1 Scope

This part of GB/T 2900 specifies general terms in the field of credibility. This section applies to all areas of credibility technology, including electrical technology applications.

2.1 basic concepts 192-01-01 Product item Consider the object. Note 1. The product may be a single component, component, device, functional unit, device, sub-system or system. Note 2. The product may consist of hardware, software, personnel, or any combination thereof. Note 3. The product is usually composed of elements that can be considered separately. See sub-products (192-01-02) and the agreed level (192-01-05). Note 4. The term "entity" is defined in GB/T 2900.13-2008 (Appendix A gives the processing of each entry in GB/T 2900.13-2008 of this section) (Entity) "is a synonym for" product ", but it is not applicable to all situations. Note 5. In GB/T 2900.13-2008 on the definition of the product, not so much a definition, as it is described. The new definition is an important alternative to the whole Text. The previously defined terms are given in Note 1. 192-01-02 Sub-product subitem Consider a part of the object. Note. Sub-products can be considered products when considered separately. 192-01-03 System (credibility field) system, independability A collection of interrelated products that together meet specific requirements. Note 1. The system has a defined real or abstract boundary. Note 2. System operation may require external resources (from outside the system boundary). Note 3. The system structure can be hierarchical, such as. systems, subsystems, components and so on. Note 4. Use and maintenance conditions should be expressed or implied in the request. Note 5. Rewritten GB/T 2900.83-2008 defines 151-11-27, and its extension is modified to follow the content of the trust. 192-01-04 Sub-system (credibility domain) subsystem, independability A part of the system itself is also a system. Note. The sub-system usually has a lower level of convention than its system. 192-01-05 Agreed level indenturelevel The hierarchical level in the system hierarchy. Examples. systems, subsystems, components, and components. Note. from the maintenance point of view, the level of agreement depends on different factors, including the complexity of product composition, accessibility of sub-products, maintenance personnel skills level, testing Equipment capacity and safety considerations. ...
