Here is an overview of the biggest changes in the new standard so you know where to spend your resources and pay attention.
The new edition takes into account the market development that has taken place over the last many years, where existing materials in particular have been challenged by new sustainable materials such as composites.
The standard describes material-relevant requirements and specifications. This means that new types of materials can be measured and weighed on the same terms as cast iron. The standard is thus intended to make it easier to see if your covers comply with the requirements – regardless of the choice of material.
The 6 significant changes in the new version are:
-
Definition of fastening function for the cover in the frame. Including both requirements for attachment, method and how to test it. It is stated i.a. requirements for traction for cover as well as which fastening functions should be used. (Appendix E)
-
Definition and values for slip resistance on the cover. (Appendix C).
-
Introduction of tests to ensure the cover does not lie and tilt. (Appendix D).
-
Recommendation for installation of manhole cover and frame. Here is a description of what preparations you should make, what equipment you should use, how it should be packed and what you should do after installation (Appendix E)
-
CE marking of cover and frame. The European Commission must approve and publish the standard before one can start CE marking.
-
Division into 6 sub-standards. The various parts include height so that new sustainable materials such as composites can be measured and weighed on the same terms as cast iron. Part 1 contains general requirements and parts 2-6 contain specific requirements for performance within different materials.
The six sub-standards are as follows:
-
Definitions, classifications, general design principles, performance requirements and test methods.
-
Cast iron.
-
Steel or aluminum.
-
Steel reinforced concrete.
-
Composite material.
-
Polypropylene (PP), polyethylene (PE) or unplasticized poly (PVC-U).
