TS 11638/T1

TS 11638/T1 is a terminology standard that defines the terms used in waste classification and provides a common conceptual framework for classifying wastes. In waste management, consistent naming is essential for clear communication, comparable records, and coherent classification decisions across different organizations and contexts.

Why waste terms are organised in a separate standard

In the waste field, expressions can vary according to source, composition, hazardous characteristics, recovery route, disposal route, or stage of management. A terminology standard reduces ambiguity in technical communication and helps the same concept be understood consistently by authorities, laboratories, and practitioners. The focus of this standard is the vocabulary connected with waste classification; it is not, by itself, a test method standard or a document that sets numerical limits or detailed procedures.

Technical context of waste classification

From a general technical perspective, waste classification helps identify where a material comes from, what physical or chemical characteristics it has, and which management route is appropriate. That distinction matters in environmental protection, health and safety, transport, storage, and recovery operations. As a terminology standard, TS 11638/T1 supports that work by organising the definitions that make different waste categories easier to distinguish and discuss.

• Defines terms related to waste classification.
• Establishes a common vocabulary and conceptual structure for waste categories.
• Supports consistent communication in environmental and waste management practice.
• Functions as a terminology standard rather than a test method or performance specification.
