The applicable British Standard in the UK for access covers and gully grates is BS EN 124:2015. This standard divides access covers, and gully grates into several classes by static test load. It also categorises the various places where they may be installed, from Group 1, the least demanding environment, to Group 6, the most demanding environment. It provides guidance on the minimum class to be used against each installation group.
