TS 11297 prEN 1330-6

TS 11297 prEN 1330-6 is a terminology standard for non-destructive testing that defines the special terms used in liquid penetrant inspection. Rather than prescribing how the inspection is performed, it gives the shared language needed for consistent reporting, training, specification writing, and technical communication.

Why penetrant inspection needs controlled terminology

Liquid penetrant inspection is used to reveal surface-breaking discontinuities. Its core technical ideas revolve around applying a penetrant, removing excess material from the surface, using a developer to draw indications out, and interpreting those indications. This standard focuses on the names and definitions of those concepts, helping ensure that terms such as penetrant, developer, inspection surface, and related wording are understood consistently across users and industries.

What this document covers

• It covers the special technical terms associated with liquid penetrant inspection.
• It is a vocabulary document rather than a procedural test method.
• It sits within the broader non-destructive testing terminology family and helps distinguish penetrant terms from those used in other methods.
• The TSE record is based on prEN 1330-6:1994 and is shown as withdrawn.

In general technical use, penetrant systems rely on capillary action to make very fine surface openings visible, and they are commonly associated with metal components, welds, and parts where surface integrity matters. Terminological precision does not change the physics of the method, but it does matter for clear documentation and for consistent understanding between inspection teams, designers, and quality personnel.
