EXAMPLE Where a cover is made of steel reinforced concrete, class D 400, and the frame is made of steel, class C 250, the manhole top or gully top is marked with EN 124-4 and the class to be declared for the combined product is the class of the frame according to EN 124-3 for steel. 4.2 Exposure classes Manhole tops and gully tops according to this standard shall be at least suitable for use in “wet and dry” conditions and a slightly aggressive chemical environment, i.e. normal conditions for domestic sewage and treated industrial effluent, and for most natural soils and ground-waters. If more severe conditions are expected, additional requirements for corrosion protection can be necessary. The exposure class determined in accordance with EN 206:2013 shall be a minimum of XC2. Where resistance against freeze/thaw or chemical attack on concrete is required, the composition and properties of the concrete shall meet the requirements for XF, XD or XA classes taking into account the relevant description of the environment in accordance with EN 206:2013. If more severe conditions are expected higher exposure classes can be necessary. In such cases the higher class shall be declared. SIST EN 124-4:2015
EN 124-4:2015 (E) 7 4.3 Resistance against freeze - thaw with de-icing salts When manhole tops and gully tops are used in specific conditions of use (corresponding to frequent contact of a surface, partially or entirely made with concrete, with standing water containing de-icing salts in frost conditions) the concrete shall not show a mean mass loss higher than 1,5 kg/m2 with no individual result higher than 2,0 kg/m2 when tested according to 6.4. Products complying with this requirement shall be marked with “+R”. 4.4 Compressive strength The compressive strength class of the concrete shall conform to the specific environmental conditions in accordance with 4.2 but not be less than C35/45 according to EN 13369, except for class A 15 covers, where the minimum compressive strength shall not be less than C25/30 according to EN 13369. 4.5 Water content of concrete The ratio of water to cement plus any pozzolanic or latent hydraulic addition in the fully compacted state shall not be greater than 0,5 and shall conform to the specific environmental conditions in accordance with 4.2. 4.6 Cement content of concrete Concrete shall have such a composition that the minimum content of cement plus any pozzolanic latent addition in the fully compacted state is consistent with the serviceability conditions of 4.2 and 4.7 for the exposure classes. 4.7 Chloride content of concrete The maximum amount of chloride ion in the concrete shall be evaluated by calculation in accordance with EN 206:2013, 5.2.8. 4.8 Water absorption of concrete When determined in accordance with EN 13369:2013, 5.1.2, the water absorption of concrete shall not exceed 6 % by mass. 5 Requirements 5.1 Design and performance requirements Manhole tops and, gully tops made of concrete shall comply with the design and performance and testing requirements in accordance with EN 124-1, as listed in Table 1.

Crack widths shall be measured on the surface optically by magnifier or equivalent. No loss of adhesion between concrete and reinforcement shall occur after the total load bearing. 5.2.3 Reinforcement and concrete cover The dimensions, the position, spacing and jointing of the reinforcement shall be in accordance with the design. The concrete cover to steel reinforcement shall be based on the provisions valid in the place of use of the concrete as given in EN 1992-1-1:2004 specific to manhole tops and gully tops or, in their absence, applicable to related products (e.g. drainage channels, pipes or manholes). Where provisions in places of use do not exist, the concrete cover to reinforcement, cmin, shall comply at least with the nominal maximum size of aggregate and be a minimum of 20 mm on all sides for class B 125 to F 900. In applying EN 1992-1-1:2004, 4.4.1.2, the following conditions are recommended for class B 125 to F 900, unless other rules are given in its National Annex: — if stainless steel or galvanized steel is used the concrete cover may be reduced by 5 mm; — when the concrete class is ≥ C40/50 and its water absorption is less than 6,0 % (characteristic value) the concrete cover may be reduced by 5 mm; — for concrete classes higher than C50/60 and water absorption less than 5,0 % (characteristic value) a reduction may be taken to 10 mm. For class A 15, the concrete cover may be reduced in accordance with EN 13369:2013, Table A.2. SIST EN 124-4:2015
EN 124-4:2015 (E) 10 Where freeze-thaw or chemical attack on concrete is expected for class A 15 to F 900, exposure class and concrete composition shall be chosen accordingly. 5.2.4 Reaction to fire Where use of manhole tops and gully tops in accordance with this standard is subject to national regulatory requirements on reaction to fire, their reaction to fire performance shall be declared. Manhole tops and gully tops made of steel reinforced concrete are classified as Class A1, regardless their cushioning insert, securing feature or coating without the need for testing (CWT), in accordance with the relevant Commission Decision1). NOTE 1 Concrete, as homogeneously distributed materials for these products (whether in combination with concrete or not), is considered as material of known and stable performance with respect to the reaction to fire performance as it does not consist of any organic material and consequently does not contribute to fire. Under these conditions it may be considered as Class A1 material. NOTE 2 The class of reaction to fire performance of manhole tops and gully tops made of concrete is regarded as the class for the constituent material. Conversely, where the use of manhole tops and gully tops is not subject to national regulatory requirements on reaction to fire, either the Class A1 (see above) or “No Performance Determined” (NPD) may be declared. NOTE 3 Where the compatibility of seatings is achieved by the use of cushioning inserts, only a negligible area of the cushioning insert material would be exposed to fire, considering the end use situation. There is no relevance in relation to the reaction to fire performance and embedded cushioning inserts would not be able to ignite or to propagate fire there. Their contribution to fire spread is not of concern, nor is an influence expected on the fire behaviour of the neighbouring material and the contribution to fire propagation is negligible. Considering these aspects, separate testing and classification of cushioning inserts is not necessary. 5.2.5 Durability 5.2.5.1 General Steel reinforced concrete is a material of known and stable behaviour with unchanging performance for the defined end use applications with respect to their application within the scope of this standard. The durability of gully tops and manhole tops manufactured from steel reinforced concrete will depend upon design features and exposure conditions (see 4.2). The prescribed framework of requirements and test methods for the mandated performance characteristics according to Clause 5 will also reflect the durability of manhole tops and gully tops 5.2.5.2 Durability of load bearing capacity Durability of load bearing capacity is ensured by meeting the requirements of EN 124-1:2015, 7.2 and 7.3 and the proportion between test load and maximum load to be expected in service and in conjunction with the stable material behaviour against weathering and environmental conditions in the place of use according to 4.2, 4.3 and 5.2.3. 5.2.5.3 Durability of securing of covers/gratings within the frame Durability of securing of covers/gratings in the frame against unintended lifting is ensured by using materials with proven resistance against corrosion and passing the test according to EN 124-1:2015, 8.4.6.
