TS EN 12303

TS EN 12303 is a terminology standard for coal tar based oils, setting out the terms and definitions used for this subject area. Standards of this kind provide a common technical language so that products and processes are identified consistently across specifications, reports and trade documents. Coal tar based oils are related to tar-derived hydrocarbon mixtures obtained from coal processing, and they are encountered in industrial contexts where heavy organic materials are described, handled or classified.

Why terminology matters in this field

Terminology standards reduce ambiguity when the same concept may be described differently by producers, laboratories, purchasers or engineers. In this document, the scope is limited to terminology and definitions for coal tar based oils; it is not a performance test method or a product specification. In chemical technology and petroleum-related fields, precise use of terms such as oil, tar, distillation fraction and related descriptors supports clearer classification, documentation and communication.

What this document covers and what it does not

• Terms and definitions for coal tar based oils.
• A shared vocabulary that supports consistent technical communication.
• Conceptual description of the product family, not production rules or acceptance limits.
• Coverage aligned with terminology use in chemical technology and petroleum-related technologies.

This listing represents the TS EN edition prepared from EN 12303 and it is withdrawn. As with other terminology standards, its value lies in defining concepts and reducing misinterpretation in technical documentation, rather than in prescribing product performance or manufacturing requirements.
