IEEE 1673-2015 PDF

This document provides specific requirements for field installed sealing between a pressurized system (stream) containing flammable or combustible process fluids which is connected directly or indirectly to an electrical system where a failure could allow the migration of process fluids directly into the electrical system. The basic requirements for electrical safety are not specifically addressed by this standard. The effects of the loss of containment of the process system in terms of risk to the environment and/or personnel health and safety are also not addressed by this document.
The purpose of this document is to provide construction and performance requirements for sealing devices that are designed to prevent flammable or combustible process fluids from entering the electrical wiring system and to prevent the propagation of an explosion through the cable or conduit system. While certain incorporate a primary seal in their design, a redundant sealing method or secondary seal as defined in NFPA 70(R) NEC(R) (501.17, 505.26) and CSA(R) C22.1 (18-072) is required to provide a backup in the event of the failure of the primary seal. These seals are intended for field installation by qualified individuals.
New IEEE Standard – Active. Provided in this document are specific requirements for field installed sealing between a pressurized system (stream) containing flammable or combustible process fluids which is connected directly or indirectly to an electrical system where a failure could allow the migration of process fluids directly into the electrical system. Not addressed in this document are the basic requirements for electrical safety and the effects of the loss of containment of the process system in terms of risk to the environment and/or personnel health and safety.
