What is BS EN 14187‑7- Cold applied joint sealants about?
BS EN 14187 is a European Standard that discusses test methods for cold applied joint sealants.
BS EN 14187‑7 is the seventh part of the multi-series that specifies a test method for the determination of the resistance to the flame of cold-applied joint sealants for use in joints in roads, airfields, and other trafficked areas.
Who is BS EN 14187‑7 - Cold applied joint sealants for?
BS EN 14187‑7 on cold-applied joint sealants is relevant to:
- Manufacturers of joint sealants
- Manufacturers and suppliers of sealing materials
- Road and airfield construction companies
- Airport authorities
- Construction industry
- Civil engineers
Why should you use BS EN 14187‑7- Cold applied joint sealants?
The resistance to the flame of cold-applied joint sealants is determined by subjecting it to the flame for a specified time.
The function test described under BS EN 14187-7 assesses the 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 cold-applied joint sealants ensures high-level sealing properties are retained due to which product failure at extreme temperatures can be avoided. 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 14187-7 is therefore determine the ignitability and burning behaviour of construction materials. This can help prevent infiltration of water and other material into the joint system.
