BS EN 14187 is a multi-series European standard on cold applied joint sealants. BS EN 14187-9 is the nineth part of the series that specifies a function test for cold-applied joint sealants intended for use in joints in roads and airfield pavements in cold climate areas where the total joint movement can be greater than 35 per cent and the temperature can go below –25°C. Compliance with the function testing can help you manufacture or select high-performance sealants that prevents end-product failure.
BS EN 14187-9 on cold-applied joint sealants is useful for:
The function test described under BS EN 14187-9 assesses damage of the cold applied sealants, arising from the influence of fluctuating temperatures, water-spraying and simultaneous dynamic load.
As concrete has the ability to expand and contract with a change in temperature, the testing of efficient cold-applied joint sealants ensures of high-level sealing properties that will not harden even at low temperatures. In particular, airfields require reliable cold-applied joint sealants to mitigate issues arising from foreign object debris.
The purpose of testing joint sealants as mentioned under BS EN 14187-9 is therefore to prevent infiltration of water and other material into the joint system.
