ISO 5872:2025 pdf download,Oil and gas industries including lower carbon energy — Pipeline transportation systems — Vocabulary.
ISO 5872:2025 is a vocabulary standard for the oil and gas (including lower-carbon energy) pipeline transportation sector. Its main purpose is to establish fundamental terms and definitions used across the pipeline lifecycle, so people can communicate consistently when designing, choosing materials, constructing, testing, operating, maintaining, and ultimately abandoning pipeline transportation systems. The document applies to pipeline systems used to transport oil and gas and helps align terminology with related ISO pipeline standards and terminology databases. It also clarifies what is outside its scope—for example, it does not cover process piping within the industrial factory areas of oil refining and chemical companies. By compiling and standardizing core definitions, ISO 5872:2025 reduces ambiguity, supports documentation clarity, and improves interoperability among engineers, regulators, and stakeholders working on pipeline projects.
