EN 124-3:2015 (E) 7 a) steel according to 4.2; b) stainless steel according to 4.3; c) aluminium alloys according to 4.4.
The minimum thickness of sheet material prior to corrosion protection shall be at least 2,75 mm for C 250 covers and above. Any element made of the materials specified in 4.1 a) to c) can be used in combination with elements of materials specified in EN 124-2, EN 124-4, EN 124-5 or EN 124-6. In such cases the manhole tops or gully tops shall comply with the relevant design and performance and testing requirements as listed in Table 1.
In addition elements shall comply with the requirements for the material related EN 124-2, EN 124-4, EN 124-5 or EN 124-6 as applicable. Each element shall be marked accordingly. The load class to be declared for the combined product shall be restricted to the lower class determined for any constituent element according to the relevant part of EN 124 series. EXAMPLE Where a cover is made of steel, class C 250, and the frame is made of PVC-U, class B 125, the manhole top or gully top is marked with EN 124-3 and the class to be declared for the combined product is the class of the frame according to EN 124-6. 4.2 Steel
4.2.1 General Steel manhole tops and gully tops shall be made from steel according to EN 10130 or EN 10025-1 and shall be resistant to corrosion. For use in normal conditions corrosion resistance can be ensured, e.g. by hot-dip galvanizing on a clean surface in accordance with 4.2.2. Prior to application of any surface corrosion protection system, manhole tops and gully tops shall be fettled.
4.2.2 Hot dip galvanizing Where corrosion resistance is achieved by hot dip galvanizing it shall be in accordance with EN ISO 1461. There shall be no sharp edges resulting from hot dip galvanizing.
After a manhole top or gully top has been hot dip galvanized it can be straightened to overcome any distortion prior to fitting the manhole cover or gully grating in its frame. Any such straightening shall not adversely affect the integrity of the hot dip galvanizing or the structure of the manhole top or the gully top. NOTE 1 Hot dip galvanization is regarded as corrosion protection system and not regarded as an aesthetic coating. NOTE 2
Other supplementary coatings can be applied to the hot dip galvanized surface, e.g. coating or paint systems.
4.3 Stainless steel Stainless steel manhole tops and gully tops for use in normal conditions (see EN 124-1:2015, 5.1) shall be fabricated from austenitic stainless steel grades 1.4301, 1.4306, 1.4307, 1.4401, 1.4404, 1.4432 or 1.4571 in accordance with EN 10088-1:2014. For normal conditions of use no surface corrosion protection system shall be required. Appropriate post fabrication finishing processes are required to avoid iron contamination, e.g. welded joints shall be treated by pickle passivation process or shot blasting. Corrosion protection or another grade of stainless steel should be required if the manhole top or gully top is subject to more severe conditions of use, e.g. in a particularly aggressive chemical environment. Stainless steel manhole tops and gully tops can be supplied with aesthetic surface finishes, e.g. varnish or paint or cleaning or bead blasting. SIST EN 124-3:2015
EN 124-3:2015 (E) 8 4.4 Aluminium alloys Aluminium manhole tops and gully tops shall be fabricated or cast from aluminium alloys according to EN 1706, EN 1676 or EN 573-3 for use under “cyclic wet and dry” conditions and a slightly aggressive chemical environment as specified in EN 124-1:2015, 5.1. Alloys having a declared copper content of less than 0,1 % shall not require additional corrosion protection. Corrosion protection can also be achieved by anodizing according to EN ISO 7599, Class AA 25. Corrosion protection systems other than anodizing or choice of alloys with specific corrosion resistance shall give corrosion protection equivalent to that of anodizing. Corrosion protection or another grade of aluminium may be required if the manhole top or gully top is subject to more severe conditions of use as given in EN 124-1:2015, 5.1, e.g. in a particularly aggressive chemical environment. Aluminium tread plates shall be in accordance with EN 1386. Their use for manhole tops and gully tops is restricted to classes A 15 to C 250. 4.5 Cover fillings
In the case of covers placed on the market in filled condition the filling shall consist of either: a) concrete with a minimum compressive strength class of C35/45 according to EN 206:2013, at least suitable for use in “cyclic wet and dry” conditions, or
b) other material complying with the intended use/place of installation expectations and with appropriate relevant European Standards at least suitable for use in “cyclic wet and dry” conditions. In the case of covers placed on the market in unfilled condition and the filling is applied subsequently, the filling materials shall have a minimum performance comparable to concrete or the surrounding pavement materials and shall fulfil the requirements of the appropriate European Standards. 5 Requirements 5.1 Design and performance requirements Manhole tops, gully tops and gratings made of materials according to 4.1 shall meet the design and performance and testing requirements in accordance with EN 124-1 as listed in Table 1.

EN 124-3:2015 (E) 10 5.2 Covers with fillings When tested in accordance with EN 124-1:2015, Clause 8, covers placed on the market filled with concrete or other filling materials and covers designed to be filled and placed on the market unfilled shall comply with requirements of Clause 4 and Clause 5.
Covers of classes A 15 and B 125, designed to be filled, placed on the market unfilled and which are capable of meeting the declared load class only in filled condition, can be filled subsequently on site with concrete in accordance with 4.5. Those covers shall comply with the requirements of Clause 4 and Clause 5 in the condition filled with concrete.
They shall be tested after being filled in accordance with the manufacturer’s instructions for filling. The manufacturer’s instructions for filling shall be supplied with the product and shall include all information for the filling procedure including the grade of the material used to ensure the declared performance after filling.
Filling materials used after the manhole top or gully top with an unfilled cover has been placed on the market, are subject to selection by the specifier or client. Their performance in service and their durability should be controlled to comply with the intended use/place of installation expectations, and with appropriate relevant European Standards. If freeze-thaw resistance is required, covers filled with concrete shall meet the freeze-thaw requirements in accordance with EN 124-4. 5.3 Material-specific characteristics for gully tops and manhole tops made of mild steel or aluminium alloys 5.3.1 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 or aluminium alloys are classified as Class A1 without the need for testing (CWT), in accordance with the relevant Commission Decision1). NOTE 1 Steel or aluminium alloys, as homogeneously distributed materials for these products (whether in combination with concrete or not), are 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 can be considered as Class A1 material. NOTE 2 The class of reaction to fire performance of manhole tops and gully tops made of steel or aluminium alloys is regarded as the class for the constituent material (e.g. steel or aluminium). 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.
