TS 10088 EN 932-3

TS 10088 EN 932-3 is a standard focused on the petrographic examination of aggregates and the simplified terminology used to describe rocks intended for aggregate use. It helps users identify the mineralogical and textural character of aggregate materials in a consistent way, so materials from different sources can be compared more reliably.

Purpose of the simplified petrographic description

Petrographic examination looks at observable features such as mineral composition, grain structure, texture, and signs of alteration. In the context of aggregates, this kind of description is used to state what kinds of rocks the material comes from and which broad descriptive features it shows. The “simplified” approach in this standard is aimed at practical classification and shared terminology for aggregates rather than detailed geological interpretation.

Why it matters in aggregate assessment

• It provides a common language for describing the rock type and origin of aggregate particles.
• It improves comparability between materials from different quarries or supply sources.
• It organises petrographic observations for general classification purposes instead of full geological reporting.
• It supports clearer use of examination results in engineering, production, and material selection workflows.

This edition of TS EN 932-3 shows that the document is fundamentally about a basic petrographic procedure for aggregates and the terminology attached to that procedure. The scope presented here defines the general classification context of the standard; it does not, by itself, justify any claim about special performance limits, detailed test thresholds, or broader laboratory calculations for specific rock types.

In practice, the standard is best understood as a terminology-and-description tool rather than a performance standard. It helps define the language used to identify the rock group, visible structural features, and descriptive terms applied during examination, which makes it a useful reference for laboratories, producers, and technical assessors who need consistent material descriptions.
