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.

EN 124-4:2015 (E) 11 5.2.5.4 Durability of skid resistance Durability of skid resistance is ensured by meeting the requirements of EN 124-1:2015, 7.4, in conjunction with the use of the relevant exposure class and the stable resistance of the material itself against loss of grip. 5.2.5.5 Durability of effectiveness of child safety characteristics Durability of the child safety characteristics concerning the resistance of manhole tops and gully tops against the removal by children is ensured by re-inspecting the weight or the locking accessory or the securing feature, as appropriate, is still functional after testing the securing in accordance with EN 124-1:2015, 8.4.6. 5.2.6 Dangerous substances National regulations on dangerous substances may require verification and declaration on release, and sometimes content, when construction products covered by this standard are placed on those markets. In the absence of European harmonized test methods, verification and declaration on release/content should be done taking into account national provisions in the place of use. 6 Testing 6.1 General Gully tops and manhole tops according to this standard shall be tested as complete units in their intended position of use where cover/grating is suitably positioned within the frame in accordance with EN 124-1:2015, Clause 8, as listed in Table 1. In addition manhole tops and gully tops made of steel reinforced concrete shall be tested according to 6.2 to 6.5. All tested products shall be visually inspected without magnification. 6.2 Concrete strength The compressive strength shall be determined in accordance with EN 13369:2013, 5.1.1. 6.3 Edge and contact surface protection The thickness of edge and contact surface protection shall be measured to the nearest 0,1 mm. The thickness of the hot-dipped galvanizing shall be measured in accordance with EN ISO 1461. 6.4 Freeze–thaw with de-icing salts The freeze–thaw resistance with de
