TS EN 12303

TS EN 12303 is a terminology standard for coal tar based oils, setting out the terms and definitions used in this technical field. Standards of this type help different parties use the same technical language when discussing materials, samples, and product families, which reduces ambiguity in quality control, trade, and engineering communication.

Why terminology matters in this product area

Coal tar based oils are materials associated with coal carbonisation processes and can vary widely in composition, appearance, and intended use. In a field where similar names may be used differently by manufacturers, laboratories, and users, a shared terminology framework is valuable. It helps distinguish concepts that may sound alike but are not necessarily interchangeable. As a terminology standard, however, this document is about naming and definitions rather than prescribing product performance or acceptance limits.

What this standard covers

According to its scope, this standard covers the terminology and definitions of coal tar based oils. In practical terms, it aims to provide a consistent vocabulary for the subject area rather than instructions for manufacture, testing, or certification. That makes it useful as a reference point for technical documentation, specification writing, and cross-border communication.

Coal tar based products sit alongside other bituminous materials and related petroleum products in industrial classification systems, so precise wording is especially important. The standard supports conceptual clarity across the sector, but it is not itself a product specification or a procedure document.

• Focuses on terms and definitions for coal tar based oils.
• Supports consistent technical communication across the sector.
• Does not set product performance requirements.
• Helps align laboratory, manufacturing, and commercial terminology.
