TS ISO 6107-9

TS ISO 6107-9 is the part of the ISO 6107 water quality vocabulary that provides an alphabetical list and a subject index for the terms used across the series. Rather than introducing new technical requirements, it serves as a structured access point to the vocabulary established in the earlier parts, helping users locate and navigate water-quality terminology efficiently.

How the vocabulary series is organised

This standard covers the alphabetical list and subject index of the terms given in ISO 6107-1 through ISO 6107-8. In general technical terms, that means it supports a very broad terminology field covering physical, chemical and biological aspects of water quality. It is useful for laboratories, environmental engineers, water managers and technical authors who need consistent access to defined terms, especially where the same concept may appear under different names or in different subfields.

Why an index matters in water quality terminology

Water-quality vocabulary spans sampling, measurement, pollutants, indicators, treatment processes and ecological status. In a multi-part vocabulary standard, an alphabetical list and subject index make it easier to trace concepts and return to the relevant definitions. The key distinction here is that this part does not set test methods or limit values; it is an organised guide to the terminology set itself. The document is based on ISO 6107-9:1997 and is now withdrawn.
