TS EN 13143

TS EN 13143 is a standard record devoted to the definitions and conventions used to describe porosity in metallic and other inorganic coatings. In practice, this kind of document provides a shared technical language for discussing coating continuity, defect appearance, and the way porous features are identified and reported across laboratories, manufacturers, and purchasers.

Why porosity matters in coating terminology

In general technical terms, porosity refers to discontinuities in or through a coating that may allow the substrate or an underlying layer to interact with the surrounding environment. That makes the concept important for corrosion protection, barrier performance, electrical behavior, and service life. The value of a terminology standard is that it reduces ambiguity: the same defect can be described consistently, even when the coating system, substrate, or inspection context differs.

How definitions and conventions support technical communication

Standards of this kind typically clarify the vocabulary used in coating engineering so that terms such as discontinuity, pore, channel, opening, and related descriptions are not mixed up. Rather than prescribing a specific test procedure, a definitions standard establishes a common framework for language, reporting, and specification writing. That helps make quality records, inspection notes, and contractual documents more consistent and easier to interpret.

This listing is based on EN 13143:2003 and is marked as withdrawn. It is therefore useful as a terminology reference for the subject area, while current projects and specifications should be checked against the latest applicable standard editions.
