Title of Technical Report:
"Municipal castings. Manhole tops. Covers, – lids and frames, – for use in vehicular and pedestrian areas."
"Particulars of product; Dimensional specification, – RD 825 mm \ 32.50 in."
"Assembly of lids and frames – heavy duty loading class – 210/250…350/400 kN / 40,000-100,000 LBS."

"Particulars of product; Dimensional specification, – RD 825 mm \ 32.50 in."
"Assembly of lids and frames – heavy duty loading class – 210/250…350/400 kN / 40,000-100,000 LBS."
Relevant documents to be considered: Basic standards, as
are AASHTO(M306), GOST3634, EN124, and others.
The dimensional particulars refers to heavy duty manhole covers of 210/250…350/400 kN or 40,000-100,000 LBS loading class – which are commonly casted by medium or high grade grey iron or medium grade ductile iron in compliance with loading class and pieces (plates/walls/reinforcements) structure.
Note!
Hinges or locking device are not subject of the Technical Report.

Measurements in metric or in English units must be considered
apart.
Mechanical
drawings in which the Technical Report consists are considered as drafts, and
there are provided as-is.
Dimensions which are not mentioned, even in the case there are or not structural thickness of pieces, are not the subject of the Technical Report, therefore each manufacturer is setting them as he considers properly.
