What is the #BS_EN_124 classification?
We explain the standard behind covers and gratings rated A15 to F900 in groups 1 to 6.
Under BS EN 124:2015, manhole covers, access covers , and gully grates are graded by different loading applications, ranging from class A15 up to F900. Each loading application has a specific meaning and it is very crucial that the right one is selected, otherwise, if the loading is wrong, the covers or gratings will not last and could become dangerous.
The loading applications are the first thing you should consider when looking to purchase manhole covers, access covers or gully grates, to guarantee that you are selecting the right one. But what is BS EN 124 and how does it help you choose the right product? Let's have a stroll down the ol' British Standard highway!
BS EN 124 history & definitions
BS EN 124 (Gully Tops and Manhole Tops for Vehicular and Pedestrian Areas) superseded BS 497:1976 Specification for Manhole Covers, Road Gully Gratings and Frames for Drainage Purposes in 1994, and was updated to become BS EN 124:2015. It is the British adoption of the European standard for covers and gratings that separates products into a number of classes based on a static load test, and also groups the locations where each class should be installed (and the minimum class that should be used in each). It was produced and is published by the BSI Group.
BSI Group (English: BSI Group), the full name of "British Standards Institute", belongs to the British International Standards statutory body. The British Standards Institute formulates product and service scope standards, and also provides supply certification and standard-related services and businesses. The British government recognizes BSI as the UK's national standards body. This includes recognition of BSI as a UK member of ISO (International Organization for Standardization) and CEN (European Committee for Standardization).
The standard is split into one general part and five material-specific parts,
and brings products made of different materials into the scope of BS EN 124.
BS EN 124-1:2015 — Definitions, classification, general principles of design, performance requirements and test methods:
BS EN 124-2:2015 — Gully tops and manhole tops made of cast iron.
BS EN 124-3:2015 — Gully tops and manhole tops made of steel or aluminium alloys.
BS EN 124-4:2015 — Gully tops and manhole tops made of steel reinforced concrete.
BS EN 124-5:2015 — Gully tops and manhole tops made of composite materials.
BS EN 124-6:2015 — Gully tops and manhole tops made of polypropylene (PP), polyethylene (PE) or unplasticized polyvinyl chloride (PVC-U).

To strictly control the ratio of raw materials, digital metering is been adopted,
which can achieve high accuracy, i.e.within 50g.
BS EN 124 Classes
Next up the classes that BS EN 124 to rate a cover's static load capabilities, ranging from A15 to F900.
Class A15 — covers and gratings capable of withstanding a 15kN test load.
