TS EN ISO 6927

TS EN ISO 6927 is a vocabulary standard for technical terms used in building and civil engineering sealants. It establishes a common terminology for self-levelling and gun-grade sealants, helping users describe product types, application behavior, and related sealing concepts with consistency across the industry.

Sealants are used in joints to reduce the passage of water, air, dust, and other external agents, while also accommodating movement between adjoining elements. In practice, precise terminology matters because joint geometry, application method, flow characteristics, and cured properties all influence whether a sealant is suitable for a given use. This standard supports that clarity by defining the language around the subject.

What this vocabulary covers

The document covers terms for sealants intended for aboveground exposed structures, with particular attention to self-levelling and gun-grade materials. In general technical context, these categories describe how the material is placed and how it behaves during application: self-levelling products flow into place, while gun-grade products are applied by extrusion from a gun or cartridge system. A vocabulary standard does not prescribe installation instructions or performance limits by itself; it provides the agreed wording needed to read specifications, test reports, and product literature consistently.

• Self-levelling sealants: materials that flow and level after application
• Gun-grade sealants: materials applied by gun or similar extrusion equipment
• Exposed structures: joints subject to outdoor environmental exposure
• Vocabulary alignment: consistent technical language for design, testing, and specification
