TS 11638

TS 11638 is a terminology standard that defines the terms used in classifying wastes and frames how waste classification is organised. Standards of this kind help different organisations and sectors use the same concepts in the same way, reducing ambiguity in waste management, environmental assessment, and technical communication.

What waste terminology is for

In waste management, the word “waste” on its own is not enough; source, hazard character, physical state, and relation to recovery or disposal all influence classification. Terminology standards make those distinctions explicit so that different waste streams can be handled under one common framework while still remaining clearly separated. This supports consistent record-keeping, labelling, transport, storage, and reporting.

What this standard covers

The scope of this standard covers the definitions of terms related to waste classification and the classification of wastes themselves. In other words, its focus is on how waste-related concepts are named and how those concepts are used within a classification system. It provides a basic reference for understanding waste in technical terms, but no special test methods, numerical limits, or operational procedures should be assumed beyond what is explicitly stated here.

In general technical context, waste classification is often linked to hazardous constituents, source activities, recycling potential, and environmental risk. Correct interpretation of distinctions such as general waste or hazardous waste depends on using the standard terminology consistently.
