TS 1729

TS 1729 is a terminology standard that brings together the definitions and conventions used when measuring the thickness of metallic and other inorganic coatings. Its role is to make the language of coating-thickness measurement consistent; it addresses how the subject is described and interpreted rather than prescribing a specific measurement process itself.

Why coating-thickness terminology matters

Metallic coatings are widely used to improve corrosion resistance, wear performance, appearance, and sometimes electrical behavior. In practice, coatings such as nickel, chromium, zinc, and tin can only be assessed meaningfully when thickness is defined in a common way. Clear terminology helps laboratories, production teams, and quality control personnel interpret measurements consistently, even when different instruments or methods are used.

Technical scope reflected in this document

Based on the supplied scope, the standard covers the terms associated with determining the thickness of metallic and other non-organic coatings applied to any material. It establishes a shared vocabulary across coating types, but nothing in the supplied record supports claims that it mandates a particular instrument, requires one test method, or sets numerical acceptance limits. Its technical value lies in consistency of naming, definitions, and measurement conventions.

TS 1729 is recorded as equivalent to ISO 2064:1973 and was adopted in 1974 before being withdrawn in 2001. It therefore serves as a historical technical reference for coating-thickness terminology rather than a current active standard.
