EN 14982:2006 (E) 4 1 Scope This European Standard specifies a test method for assessing the initial (short-term) tangential ring stiffness of riser shafts for thermoplastics inspection chambers or manholes. NOTE
This is intended as a test of the structural integrity of riser shafts supporting product standards prEN 13598-2 [1] and prEN 15229 [2]. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN ISO 9969,

Rubber, vulcanized or thermoplastic Determination of hardness (hardness between 10 IRHD and 100 IRHD) 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 inspection chamber drainage and sewerage fitting used for the connection of drainage or sewerage installations and/or for changing the direction of drainage/sewerage runs. 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 inside 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 equipment and the removal of debris and also providing access for personnel. 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 requirements. 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, injection moulding, blow moulding or rotational moulding
EN 14982:2006 (E) 5 3.5 irregular cross section shaft riser shaft with an irregular asymmetrical design on its 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 determined 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. Table 1 – Relevant standards for determination of ring stiffness External shaft design Type of cross-section Relevant standard for determination
of ring stiffness Regular cross-section
and circular EN ISO 9969 Plain surface Irregular cross-section, circular or square or rectangular EN 14982 Regular cross-section
and circular EN ISO 9969 Structured wall surface 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 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 necessary to produce a deflection of 0,03di diametrically 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 load, 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 compr
