Standard EN Sample
Products and Systems for the Protection and Repair of Concrete Structures - Test Methods - Determination of Open Time
Also Known As:
BS EN 12189:1999 is a standard that outlines test methods for determining the open time of products and systems used for the protection and repair of concrete structures. The open time refers to the period during which a bonding agent remains workable before it starts to set or cure.
The standard specifies a specific testing procedure that involves bonding concrete prisms together and subjecting them to flexural testing. By measuring the time it takes for the bonding agent to lose its workability and the concrete prisms to fail, the open time can be determined.
This standard is important in the construction industry as it allows manufacturers, contractors, and engineers to assess and compare the performance of bonding agents used in concrete repair and protection applications. Understanding the open time of a product helps ensure that it can be properly applied and that sufficient time is available for bonding and repair work to be completed.
