IEEE P62.42.1/D3, October 2014

P62.42.1/D3, October 2014 is a technical standard focused on Part 1 Gas Discharge Tubes (GDTs), with relevance to power, energy, and industrial applications as well as components, circuits, devices, and systems. It is useful for defining the expected characteristics, evaluation approach, and documentation needed when selecting or comparing GDTs for surge protection and related engineering work. For teams handling procurement, design, or compliance, P62.42.1/D3, October 2014 helps anchor decisions to a common technical reference.

P62.42.1/D3, October 2014 overview

This standard provides a specific framework for understanding gas discharge tubes as protective components in electrical and electronic systems. Its focus on Part 1 suggests a foundational document that may address core definitions, ratings, or test considerations for GDTs rather than a broad system-level specification. In practical use, P62.42.1/D3, October 2014 supports consistent evaluation of device behavior under electrical stress, helping engineers and buyers align on performance expectations, terminology, and acceptance criteria for this component category.

Typical use cases

P62.42.1/D3, October 2014 is typically relevant when specifying GDTs for surge and transient protection in equipment exposed to electrical disturbances. That can include power distribution interfaces, industrial control hardware, communications entry points, and other circuits where controlled discharge behavior is important. It may also support component qualification, supplier comparisons, and internal testing workflows for designs that rely on repeatable protection performance. For technical teams, the standard helps connect device selection to the requirements of the end application.

Why this standard matters

In practice, this standard matters because GDT performance can affect safety, reliability, and long-term equipment integrity. Clear requirements help reduce uncertainty during design review, procurement, and acceptance testing, especially when multiple component options are being considered. P62.42.1/D3, October 2014 can support more consistent communication between engineering, quality, and sourcing teams by defining a common technical basis for evaluation. That consistency is valuable when controlling risk in power and industrial applications where transient protection is a critical design element.
