Standards Development
This document specifies the general rules and technical requirements for the prognostics and health management (PHM) system for rolling stock.
This standard is applicable to the diagnostics and prognostics for rolling stock subsystems and components.
1 Scope Data collection Diagnostics Prognostics PHM system Operation and maintenance Data Ground and onboard data Data Remaining useful life Health indicators
Purpose and justification for developing the international standard Benefits after standard implementations
1. Technological benefits
Fault diagnostic and prognostic technologies have been widely used in rolling stock in different countries, guided by certain common frameworks. According to our survey of numerous application cases, the feasibility of standardization is relatively high.
2. Economical benefits
PHM system can be used on rolling stock to reduce operation/maintenance costs.
3. Social benefits
The efficiency of maintenance of rolling stock can be improved with PHM system.
The safety and reliability of rolling stock operations can be enhanced with PHM system.
4. Intended benefits
This standard facilitates the definition and use of PHM system for railway rolling stock applications.
