TS ISO 1998-6

TS ISO 1998-6 is a terminology standard focused on measurement in the petroleum industry. It brings together the terms and definitions used for measuring crude oil and petroleum products, helping ensure that the same concepts are understood consistently across technical, commercial, and operational documentation.

Where measurement terminology matters

In the petroleum sector, measurement is closely tied to quantities such as volume, mass, density, temperature, and related corrections. These measurements are central to custody transfer, inventory control, shipping, and production accounting. In that context, a terminology standard is valuable because it standardizes language rather than prescribing a measurement method. The emphasis is on clear definitions, not on a single test procedure or numerical limit.

What this part covers in general terms

• Terms related to measurement of crude oil and petroleum products
• Consistent definitions for measurement-related concepts
• Terminology support for technical, commercial, and documentation use

As general technical context, measurement vocabulary helps separate ideas such as sampling, density correction, temperature effects, volume standardization, and data recording. That distinction is important because petroleum measurement often combines physical properties with commercial decision-making. TS ISO 1998-6 therefore serves as a language reference within the wider petroleum terminology framework. This record is withdrawn, but the subject area remains relevant for understanding how petroleum measurement concepts are defined and communicated.
