DN630 - Grey cast iron manhole cover - Loading class 400 kN
A PROPOSAL ON THE SUBJECT OF PRIVATE STANDARDIZATION
THE SUBJECT OF INDUSTRY STANDARD DEVELOPMENT
THE PROPOSAL - Title of proposal:
"Dimensions of special product of vehicular area manhole cover, of round opening, of cast iron construction, size DN.630mm or 25in (D.630/635), and 360/400 kN loading class."
Material: - grey cast 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 document (as case, in form of a publication/deliverable) concerning the dimensions of special product of a street manhole cover - in order to be in concordance and to complete 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.
Thus, the proposed private standard document (norm) aims to specify the main dimensions for a special product of a cast iron vehicular area manhole cover of DN.630mm / 25in, 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: 630mm (24.8125in),
- top opening of frame: dia. 635mm (25in), - round,
- top dia. of frame: 680mm (26.75in), - round
- inner opening of base of frame - dia. 582; 670; 717; 757; 825mm (23; 26.375; 28.25; 29.8125 32.50in), to fit a 600; 650; 700; [750]; 800mm (24; 26; 28; 30; 32in) dia. of manhole top opening.
- clearance (clear opening) of frame, - about 575mm ( 22.625in),
- 4 vent/key holes of about 40 sq.cm. (~6.20sq.in) at all clear opening;
which also allow an easy opening using common tools,
- optional, blocks for locking system fixing may be added, - on backside of lid piece.
As conclusion, the proposed document (norm) aims to specify the main dimensions for a special product of a cast iron vehicular area manhole cover of DN.630mm (D.630/635) / 25.00in round opening; - and must, as case may be, completed with other standards which refers to testing, marking, quality control. (e.g. EN124 CEN standard).
The type of public standard document, as possible the proposal may later transform into:
> concerning the terminology of EN45020:2006 description: - pre-standard (3.3), product standard (5.4), technical specification (3.4), unilaterally aligned standard (6.8), - all of these aligned (related) to the EN124 CEN standard 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).
