About This Item
1142-2009 is a technical standard focused on moisture barriers and/or longitudinal water blocking for power, energy, and industrial applications. It addresses how barrier and blocking materials are used to limit the movement of moisture along cables or related constructions, helping support reliability in service. For systems exposed to damp environments, buried installations, or other moisture-prone conditions, this specification can be an important reference for design and procurement decisions.
Overview of 1142-2009
This standard provides guidance around moisture control features used in electrical and power-related assemblies, with emphasis on longitudinal water blocking and moisture barrier performance. In practical terms, it helps define expectations for materials and construction methods intended to reduce moisture migration after exposure or damage. The document is relevant where cable integrity and environmental resistance are important, and it may be used alongside other engineering requirements for insulation, protective layers, and installation conditions.
Typical use cases
1142-2009 is commonly relevant for power cables, utility distribution equipment, and industrial wiring systems where moisture ingress can affect performance. It may be used when specifying materials for underground runs, wet locations, or installations that need additional protection against water travel along the cable length. Engineers, purchasers, and test teams may refer to it when evaluating barrier materials, blocking compounds, or construction details for field reliability in energy infrastructure.
Why it matters
Moisture management is a practical issue in many power and industrial applications, and 1142-2009 helps bring consistency to that area. Using a clear standard can support better design control, improve comparison between products, and reduce uncertainty during acceptance or testing. It also helps limit the risk of moisture-related failures that can lead to service disruption, maintenance costs, or shortened equipment life. For organizations working with cable systems, the standard can support more dependable specification and procurement choices.
