TS 7242

TS 7242 is a terminology standard that gathers terms and definitions used in the field of water quality. Its focus is on establishing a shared meaning for concepts used to describe the physical, chemical, and biological condition of water. In practice, water quality work spans environmental monitoring, drinking water, surface waters, wastewater, and aquatic ecosystem assessment, all of which depend on consistent language.

The role of water-quality vocabulary

Terminology standards do not define test methods or numerical limits; they organise the names and meanings of technical concepts. In that sense, TS 7242 supports conceptual consistency for users who prepare reports, compare data, interpret laboratory results, or write technical documents. In water-quality contexts, terms such as turbidity, dissolved oxygen, pH, conductivity, nutrient levels, and pollutant load may be used across disciplines with subtle differences, so common definitions are especially valuable.

What this document covers in general terms

• Terms relating to water quality and their definitions
• A common vocabulary for environmental and technical use
• Conceptual alignment for monitoring, assessment, and reporting
• A reference framework that supports terminological consistency

This standard was published as equivalent to ISO 6107-6:1986 and was later withdrawn. It therefore serves as a historical reference for standardised water-quality vocabulary, rather than as a method standard, performance specification, or product requirement.
