TS ISO 6078

TS ISO 6078 is a vocabulary standard for black tea. It brings together the terms and definitions used for the processing and assessment of black tea in commercial contexts, helping to keep technical language consistent across production, trade, quality control, and related documentation.

What this black tea vocabulary organizes

The focus of this standard is not the tea product itself, but the language used to describe it. Black tea is the tea category obtained through processing that develops the characteristic colour, taste, and aroma associated with fully oxidized tea. Vocabulary standards reduce ambiguity around processing steps and evaluation terms, so manufacturers, laboratories, traders, and inspectors can use the same technical meanings.

Commercial processing and assessment context

According to its scope, this standard covers terms and definitions applicable to the techniques used in processing and assessing black tea. In general technical usage, that includes post-harvest operations such as withering, rolling, oxidation, and drying, as well as the language used to describe quality attributes such as appearance, leaf integrity, colour, and aroma. The value of such a standard is consistency: it links practical tea-sector terminology to a shared technical vocabulary.

• Standardizes the meaning of terms used in commercial tea communication.
• Covers concepts related to black tea processing and assessment.
• Functions as a vocabulary reference rather than a product specification.
• Helps reduce confusion caused by differing tea-sector naming practices.
