Product Standard
HFL products are manufactured as per BS EN 124-2 with all key criteria such as load-bearing ability with extra features of said product.
- Access covers and gully grates installed in Doha should meet the requirements of the European Standard BS EN 124.
- This applies to all situations, on and off-load and to all materials.
- Products designed to BS EN 124 are grouped and classified depending on their place of installation.
- It is the responsibility of the engineer to ensure that the correct product is specified.
- The appropriate class of manhole top or gully top to be used depends upon the place of installation
- The selection of the appropriate class is the responsibility of the designer.
- Where there is any doubt the stronger class should be selected.
- This standard divides access covers and gully grates into a number of classes by static test load. It also categorises the various places where they may be installed from Group 1, the least demanding environment, through to Group 6, the most demanding environment. It provides guidance on the minimum class to be used against each installation group.
