This standard has made the following editorial changes.

--- China's credibility standard system is currently based on an independent standard system structure, in line with China's existing credibility standards system,

Introduction

Reliability, maintainability and availability are the basic characteristics of the system. These features, together with maintenance support, constitute a system we know well.

Believe.

In the system, any characteristic of credibility is important, as other characteristics of the system's technical indicators, size and quality, etc.

Define and define in the same way.

The level of reliability, maintainability, availability, and maintenance support of the system depends on the conditions of use of the system, ie the tasks of the system.

section. When system credibility requirements are specified, it is essential to clarify the future storage, transportation, installation and use conditions of the system. important

It is necessary to consider the conditions under which the system operates, as well as the system maintenance strategy and maintenance support organization.

In order to assess the magnitude of the system's credibility characteristics, the application of statistical models is essential.

As with other performance characteristics of the system, the credibility feature can be specified in three ways.

1) specifications written by the supplier;

2) specifications prepared by the purchaser;

3) Specifications negotiated or prepared by the supplier and the purchaser.

This standard applies to all three types of specifications described above.

IEC 62347 deals with the definition of the system and its components and how these elements are defined. This standard supplements IEC 62347 and

The credibility requirements of these elements are specified. The primary task of IEC 62347 is to identify system requirements from a system engineering perspective and

A process for converting a purchaser's perspective on the application of a system into a systematically engineered technical overview. IEC 62347 emphasizes the structure of functional implementations and

Functional design, through the appropriate selection of hardware, software and personnel factors to achieve the system-related credibility requirements of the purchaser.

Application Guide Credibility Requirements Specification Guide

1 Scope

This standard gives guidelines for the credibility characteristics specified in the specification, as well as methods and criteria for verification and validation of these characteristics.

This standard includes the following.

--- Recommendations for specifying quantitative and qualitative requirements for reliability, maintainability, availability and maintenance support;

--- System purchaser's advice on how to ensure that the supplier meets the specified requirements;

---Help the supplier to meet the buyer's requirements.

Other documents, such as laws and government regulations, may also be required by the system, except for any specifications consistent with this standard.

Should be considered for adoption.

NOTE 1 Although the system and equipment level reliability is primarily addressed, the methods described in the different sections of IEC 60300 apply equally to the product, unit or component level. The

The term system is used throughout this standard.

Note 2. This standard does not give an indication of the credibility management program and the activities required to achieve the required availability, reliability, maintainability and maintenance support requirements.

south. See these other guidelines for these general guidelines.

Note 3. This standard does not directly consider safety and environmental specifications. However, many of the guidelines in this standard also apply to safety or environmental regulations.

Note 4. This standard does not consider the credibility norms of services, including the terms of service provided through the procurement of public-private partnerships.
