TS EN 13318

TS EN 13318 is a terminology standard for screed material and floor screeds. It establishes the technical meanings of the terms used when screed materials are produced, specified and applied, helping designers, manufacturers and contractors use a common vocabulary in work related to flooring systems.

How screed terminology is organised

In general building practice, a screed is the layer applied to a floor to smooth, level or prepare the surface for its intended use. Screed materials are the ingredients and formulations used to create that layer, including the binder, aggregate and related constituents. The value of this standard lies in defining the terms themselves, so that categories such as screed types, application concepts and material descriptions are understood consistently across technical documents.

Why a terminology standard matters

Screeds play an important role in residential, commercial and industrial flooring because they contribute to flatness, load distribution and readiness for the final floor finish. As a terminology standard, TS EN 13318 does not set performance values or prescribe a test method; instead, it supports consistency across the wider family of standards by aligning the language used for these materials and systems.

• Standardised definitions for screed materials and floor screeds
• A shared terminology base for standards prepared by CEN TC 303
• Clear separation between material, application and floor-layer concepts
• Reduced ambiguity in specifications, product descriptions and technical guidance
