What is ISO 10591 about?
ISO 10591 specifies a method for the determination of the influence of water on the adhesion/cohesion properties of sealants with predominantly plastic behaviour which are used in joints in buildings and civil engineering works.
Who is ISO 10591 for?
ISO 10591 on the determination of adhesion /cohesion properties of sealants is useful for:
- Manufacturers of sealants
- Contractors
- Civil engineers
Why should you use ISO 10591?
Sealants are used in construction to prevent fluids and other substances from passing through material surfaces, joints, or openings. They can also prevent the passage of air, sound, dust, insects, and so on, as well as acting as a fire-stopping component.
ISO 10591 provides you with the necessary test methods to determine the adhesion/cohesion properties of sealants after immersion in water.
ISO 10591 provides preparation methods of test specimens in which the sealant is to be tested after being immersed in water under defined conditions to check the rupture and the elongation at break in the construction.
ISO 10591 also gives information about the apparatus or materials used in laboratory tests to get the dimensions of the sealant bead and the area of adhesion.
Overall, ISO 10591 will enable you to manufacture and select high-quality sealants that provide flexibility, durability and strength against moisture conditions, for your specific engineering needs. Establishing structural integrity with standardised test performance and results will also enhance the reliability and credibility for your products and services.
What’s changed since the last update?
BS EN ISO 10591:2021 supersedes EN ISO 10591:2005. BS EN ISO 10591:2021 includes some technical changes with respect to EN ISO 10591:2005. These include:
- The title of the document has been modified
- The range of variation of extension rate has been changed to (5,5 ± 0,5) mm/min
- The range of variation of relative humidity has been changed to (50 ± 10) %
- The operation sequence for the cleaning substrate materials has been added
- The expression of results has been improved by showing a formula with descriptors
