This Practice describes an engineering work process for gathering the necessary information and applying the applicable codes and standards to develop a documented area classification. This Practice addresses the classification of areas containing flammable liquids, gases, or vapors and combustible dust, but does not address ignitable fibers and flyings.This Practice applies to petroleum and chemical process facilities and other related industries that fall within the scope of the standards being used for the assessment of the area classification. This Practice is applicable for new and existing facilities.This Practice should be used with petroleum and chemical industry codes and standards that define the basis for area classification.

This Practice covers the basic requirements for the lubrication of antifriction and hydrodynamic bearings used in electric motors. These requirements apply to induction, synchronous, and DC motors.Excluded from this PracticeOn site vibration analysisOn site mechanical equipment alignmentRepair of the motor, e.g. bearing replacement, rotor repair, stator repair, etc. (PIP ELTFT04 addresses motor repair.)

​This Practice is an overlay to the IEEE document IEEE Std. 1068-2015, IEEE Standard for the Repair and Rewinding of AC Electric Motors in Petroleum, Chemical, and Process Industries. The intent is to use IEEE 1068-2015, with the exception and clarification as given in below, along with PIP ELTFT04-D and ELTFT04-T to define the requirements for repair, modification, and testing of electric motors.

This Practice covers minimum requirements for the maintenance of switchgear. While the maintenance procedures herein can be applied to all types of switchgear, manufacturer instructions should be reviewed for equipment specific maintenance requirements.This Practice does not cover the calibration, settings, or programming of protective devices such as molded case circuit breakers, protective relays, etc.

This Practice provides standardized reliability terminology and a basis for measurement and data gathering for benchmarking the reliability of rotating machinery. This Practice describes reliability terms and definitions that can be applied to economic performance data generation. This Practice describes reliability data gathering techniques. This Practice provides basic steps to implementing reliability indicators in process industry facilities. This Practice describes levels of data gathering and analysis that may be used to provide the appropriate amount of reliability information.
