TS 4607

TS 4607 is a terminology standard that defines the terms used in the petrographic analysis of coal. Coal petrography is the specialist field that examines the microscopic features of coal to understand its organic components, structure, and characteristics related to formation; in that context, clear and shared definitions are essential for consistent interpretation of analytical results.

The role of terminology in petrographic analysis

This standard is concerned with the language of the subject rather than the test procedure itself. In coal petrography, concepts such as vitrinite, inertinite, liptinite, reflectance, texture, and maceral groups are central to comparing samples and writing consistent reports. As a terminology standard, the document is intended to align technical meaning, not to prescribe detailed methods or numerical acceptance limits.

Practical context and technical value

Petrographic terms support coal classification, quality assessment, research work, and laboratory reporting by providing a common conceptual framework. A vocabulary standard like this reduces ambiguity between laboratories and specialists, especially when results are based on microscopic observation. The scope of TS 4607 is limited to the definitions of terms used in the petrographic analysis of coal, so it standardizes the terminology rather than the analytical procedure itself.
