Overview
EN ISO 6927:2021 - Buildings and civil engineering sealants - Vocabulary (ISO 6927:2021) is a harmonized CEN/ISO vocabulary standard that defines the technical terms used for self‑levelling and gun‑grade (gunnable) sealants intended for above‑ground exposed structures. The 2021 edition supersedes EN ISO 6927:2012 and standardizes terminology across manufacturers, specifiers and test laboratories to improve clarity in specifications, testing and product development.
Key topics covered
The standard organizes and defines terminology across several practical domains:
Practical applications and users
EN ISO 6927:2021 is a vocabulary resource rather than a prescriptive performance standard. Typical users include:
- Manufacturers - for consistent product datasheets and labeling.
- Architects and specifiers - to write unambiguous specifications for façade, glazing and expansion joints.
- Contractors and façade installers - to interpret installation instructions and select appropriate sealant types (self‑levelling vs gun‑grade).
- Test laboratories and conformity assessors - to ensure test reports use standardized terminology.
- Research & development teams - for product development and cross‑industry communication.
Using a common vocabulary reduces ambiguity in procurement, testing and regulatory compliance for building and civil engineering sealant systems.
