TS 1729 EN ISO 2064

TS 1729 EN ISO 2064 is a terminology standard for how thickness measurement of metallic and other inorganic coatings is described and discussed. Its role is to align the concepts used around coating thickness so that measurement results, reporting language, and technical communication refer to the same physical idea.

Why coating-thickness terminology matters

Coating thickness is a key dimensional property in surface engineering and quality control. Metallic coatings may be applied for decoration, corrosion protection, wear resistance, or functional electrical performance. Inorganic coatings can be produced by different processes, so clear terminology helps avoid confusion when the same terms are used in specifications, test reports, or laboratory practice.

Technical scope of this document

• Defines terms related to the measurement of thickness of metallic and other inorganic coatings.
• Applies to coatings on any substrate.
• Provides a common vocabulary for thickness-related measurement reporting.
• Supports consistent understanding of the terms used when evaluating coating thickness.

From a general technical perspective, the value of a terminology standard lies in clarifying what a measurement statement actually means, rather than prescribing a specific measuring method. That makes concepts such as nominal thickness, local thickness, and average thickness easier to use consistently across coating engineering, material characterization, and surface inspection work.
