24、ns. An inspection chamber terminates at ground level, permitting the introduction of cleaning, inspection and test equipment and the removal of debris but it does not provide access for personnel. The riser shaft connected to these fittings has a minimum outside diameter of 200 mm and a maximum insi
25、de diameter of less than 800 mm 3.2 manhole drainage and sewerage fitting used for the connection of drainage or sewerage installations and/or for changing the direction of drainage/sewerage runs. A manhole terminates at ground level, permitting the introduction of cleaning, inspection and test equi

The minimum inside diameter of a manhole riser shaft is 800 mm 3.3 structured-wall ancillary fitting fitting with an optimized structural design with regard to material usage, but which still achieves the relevant performance r

These fittings could be circular or rectangular in design 3.4 regular cross section shaft riser shaft either fabricated from plain pipe or from structured wall pipe or fittings with a regular symmetrical design on their external surface. These products could be manufactured by extrusion

29、 external surface such as those with additional reinforcing rings or structures intended to strengthen the riser in specific areas. These products could be manufactured by extrusion, injection moulding, blow moulding or rotational moulding 4 Principle 4.1 General The ring stiffness of a shaft is det
30、ermined using the EN ISO 9969 test method when the shaft has a circular and regular cross-section. Where a shaft has a square or rectangular cross-section, or if the shape is irregular, then the EN ISO 9969 test is modified as described in this standard to determine the ring stiffness. See Table 1.

32、 wall surface Regular cross-section and circular EN ISO 9969 Irregular cross-section, circular or square or rectangular EN 14982 4.2 Principle for shafts with circular and regular cross-section The ring stiffness is determined by measuring the force and the deflection while deflecting the shaft at a
33、 constant rate. A length of shaft supported horizontally is compressed vertically between two parallel flat plates moved at a constant speed which is dependent upon the diameter of the shaft. A plot of force versus deflection is generated. The ring stiffness is calculated as a function of the force
34、necessary to produce a deflection of 0,03didiametrically across the shaft. 4.3 Principle for shafts with circular and irregular cross-section or, square or rectangular The ring stiffness is determined by measuring the force and deflection whilst deflecting the shaft at a constant rate or constant lo
35、ad, until sufficient force is applied to obtain a resulting deflection in the range of 2% to 6%. A riser shaft or segment of shaft is placed symmetrically between two rigid parallel plates or beams or alternatively between one rigid beam and a V-shaped support. A compressive force is applied to the
36、shaft or segment using a bearer shaped to the external surface of the test piece.

39、shaft 5.2.1 Loading frame, with two rigid parallel plates or beams between which a compressive force can be applied to the test piece so that the force and the resulting deflection of the test piece in the direction of the force can be measured with an accuracy of 1 %. Where a V-shaped support is us
40、ed, the included angle shall be 170 or more. For shafts with square or rectangular cross sections the bearers shall have a width W not greater than 25 mm. For circular shafts with irregular cross section the maximum width of bearers shall be for: DN/ID 400: 50 mm; 400 1 200: 150 mm. NOTE The above v
41、alues have been taken from 9.2.1 of EN 476:19973. Where the outside of an irregular shaft has a change in cross-section incorporated within the test piece, the bearers shall be shaped to accommodate this (see Figure 4). Where square or rectangular shafts have a regular rib configuration this shall n
42、ot be considered not to be a change in cross-section, and the load imposed shall be applied just to the crests of the ribs. The centre of loading shall be so arranged that the vertical deflection of the two ends of the test piece differs by not more than 0,5 % of the nominal size of the shaft. Where
43、 the surface of the outside of the shaft does not provide a smooth bearing contact, the bearers shall be surfaced with a strip, not less than 3 mm thick, of elastomeric material of (50 5) IRHD hardness in accordance with ISO 48. The length of each bearer shall be not less than the length of the test
