Overview - ISO 18651-1:2011 (Internal vibrators for concrete)
ISO 18651-1:2011 defines the terminology and commercial specifications for internal (immersion) vibrators used to compact concrete mixes. It standardizes names, component types and the data that manufacturers and suppliers should provide so buyers, specifiers and users can compare products, ensure correct selection, and communicate technically consistent requirements.
Key topics and technical requirements
The standard addresses terminology, structure and the commercial data that must accompany immersion vibrators. Important elements include:
