THE PROPOSAL
Title of proposal:"Dimensions of special product of vehicular area manhole cover, of round opening, of ductile iron construction, rated size - DN.650mm or 25.80in (D.650/655), and 360 or 400 kN loading class."Material: - ductile iron - of grade to fit the loading class in compliance with thicknesses of pieces.
The proposal comes to settle up a dimensional based private standard normative document (as case, a publication/deliverable) concerning the dimensions of a special product of a street manhole cover - in order to be in concordance with requirements of one or more regional basic standard(s) of cast/ductile iron manhole covers, - e.g. the regional CEN standard "EN124 - Gully tops and manhole tops for vehicular and pedestrian areas. Design requirements, type testing, marking, quality control", - or, with other basic standard concerning street, or residential area, manhole covers - as long as the basic standard (e.g. as the EN124 is) does not apply for dimensions of special products of manhole covers.
As conclusion, the proposed private standard document (norm) aims to specify the main dimensions for a special product of a ductile iron vehicular area manhole cover of a DN.650mm / 25.80in, rated dia. of round opening; - and must, as case may be, completed with other standards which refers to testing, marking, quality control. (e.g. the EN124 CEN standard).
Short description of design related to product and main dimensions:
= Round (circular) frame with round opening;
- overall dia. of lid piece: 650mm (25.625in),
- top opening of frame: dia. 655 (25.75in), - round,
- top dia. of frame: 700mm, (27.5625in), - round,
- lower (inner) opening of base of frame,
dia. 610mm (24in); 685mm (27in); 710mm (28in), 765mm (30.125in), 825mm (32.50"),
> to fit a manhole top opening (entry) of dia. 600mm (24in), 27in, 700mm (28in), 750mm (30in), 800mm (32in)
- clearance (clear opening) of frame, - about 600mm (23.625in),
- 4 vent/key holes of about 40sq.cm. (~6.20sq.in) at all clear opening;
which also allows an easy opening using common tools,
- optional, on designs of lid and frame - a hinge or locking system may be added.
The product which the subject of standardization consists in, may be useful for outdoor networks - water supply, as well sewerage chambers or storm water, - in vehicular areas.
The type of public standard document, as possible the proposal may later transform into:
> concerning the terminology of EN45020:2006 description: - prestandard (3.3), product standard (5.4), technical specification (3.4), unilaterally aligned standard (6.8), - all of these, in order to complete with CEN standard EN124, which is a basic standard (5.1).
> concerning the terminology of ISO/CEI-2:2004: - international standard (3.3), technical specification (3.4), technical report (3.5), publicly available specification (3.7).
