Practices by Discipline

​This Practice outlines a process to evaluate electrical equipment (e.g., transformers, motor controllers, protective relays, etc.) in terms of degree of obsolescence. Based on the degree of obsolescence and the risk presented from equipment not being available to produce product, this Practice outlines a method to determine the timing of refurbishment or replacement of electrical equipment. ​

This Practice provides information for performing an arc flash hazard analysis as required by NFPA 70E and IEEE C2. It provides guidance on the determination of the arc flash boundary, the incident energy at the working distance, and arc flash pressure. This information can be used to mitigate the possibility of an arc flash event through engineering controls or in the proper selection of personal protective equipment (PPE). Arc flash risk assessment, as required by NFPA 70E, is outside the scope of this document.

​This Practice describes guidelines for design and construction of aboveground storage tanks with uniformly supported bottom foundations based on US customary units. Applicable industry codes and standards are referenced, and data required to determine the most appropriate foundation for a tank are presented. In addition, this Practice addresses tank foundations for different types of soil conditions. This Practice also includes information on settlement and tolerances.​

​This Practice describes the guidelines for selection and installation of instrumentation for liquids and solids level measurement. This Practice does not include guidelines for tank gauging systems or weighing systems. ​

​This Practice provides leak-test procedures, practices, and precautions for piping designed and constructed to ASME B31.3, hereinafter referred to as the Code, and describes requirements that are in addition to those in the Code.

​NA

​Applicable parts of the following industry codes and standards shall be considered an integral part of this Practice. The edition in effect on the date of contract award shall be used, except as otherwise noted. Short titles are used herein where appropriate.​

​This Practice provides requirements for the installation of monolithic refractory linings in process equipment and piping. Included are preparation, installation, curing, and repair of the linings. This Practice also covers heat dryout of newly installed or repaired linings​.

​This Practice provides overall guidelines on the application of Process Safety Management and how to incorporate these principles into a project. ​

​This Practice describes the minimum requirements for design, fabrication, inspection, testing, shipment, and documentation for a Solar Photovoltaic (PV) Energy system. The Solar PV Energy system consists of a Solar PV Array, which produces DC power. The DC power can connect directly to a DC grid, or it can be connected to an AC grid with the use of an inverter that converts the DC power from the Solar PV Array to AC power. The Solar PV Energy system described in this Practice is intended for use in commercial or industrial applications. It is not intended for use in residential applications.
