This recommended practice describes how to determine the impact of preventive maintenance on the reliability of industrial and commercial power systems. It is likely to be of greatest value to the power-oriented engineer with limited experience in the area of reliability. It can also be an aid to all engineers responsible for the electrical design of industrial and commercial power systems.

General technical recommended practice for operation of pulverized coal-fired boilers in power plants is provided, including start-up, shutdown, operation and maintenance, and emergency and failure detection/handling/prevention. In this document, a boiler with existing single units with a capacity of 300 MW to 600 MW in thermal power plants, where pulverized coal is combusted to generate electricity and/or to supply heat, is discussed. Development of boiler operation code as a reference to determine detailed operation steps and/or procedures for a particular boiler in the plant is outlined. The specifications of manufacturers, successful experiences from practice, and stipulations defined in other related high-level standards/regulations/codes are also considered.

"Provides information and insights on the factors that determine the useful service life of engineering components and the likely timing and mode of failure. It addresses nearly every stage of the product lifecycle from materials selection and design to manufacturing, operation, maintenance, and repair. It explains how to use life assessment methods to evaluate the effect of corrosion, fatigue, brittle fracture, elevated temperature, and other forms of damage. It also includes a section that examines the effects of casting, forming, welding, heat treating, and other manufacturing processes on component lifetime and performance. The final and by far largest section in the volume presents and analyzes the failure of metal shafts, fasteners, bearings, springs, and gears as well as pressure vessels, boilers, heat exchangers, pipelines, bridges, cranes, rail equipment, and medical devices."--

A common format for the data files and exchange medium needed for the interchange of various types of fault, test, or simulation data is defined. Sources of transient data are described, and the case of diskettes as an exchange medium is recommended. Issues of sampling rates, filters, and sample rate conversions for transient data being exchanged are discussed. Files for data exchange are specified, as is the organization of the data. A sample file is given.
