scope:

This ISO Standard specifies the definitions and requirements for thermoplastics covers and frames for manholes, inspection chambers and other such pipeline access products installed in light vehicular access and pedestrian areas and manufactured from unplasticized poly(vinyl chloride) (PVC-U), polypropylene (PP), polypropylene with mineral modifier (PP-MD) or polyethylene (PE). The products are rated up to B 125 max. (see clause 7) and are intended for use either inside or outside buildings including swimming pool areas but are not intended for use in the carriageway of trafficked areas. This ISO Standard is only applicable to those covers and frames where the manufacturer has clearly stated in the documentation how the frames are installed and assembled to the intended access product, identifying as necessary the manufacturer and grades of product or riser to which the frame is intended to fit. Note 1: The cover and frame shall normally be manufactured by injection moulding, low pressure moulding or roto-moulding. Note 2: Fibre reinforced covers and frames are not covered by this standard
