40、of the septic tank, allows it to be fitted flush with the ground surface or slightly above ground surface, permits installations to be fitted below the frost line, allows accessibility and enables maintenance work to be carried out. Depending on the requirements, it may be vertical extension pieces
41、of the installation housing, or components, which are fitted over maintenance access holes and manholes 3.2 nominal capacity (NC) numerical designation of the volume of a septic tank, expressed as an integer in cubic metres 3.3 prefabricated septic tank single piece factory made unit, including inle
42、t and outlet level openings which leaves the factory completed, controlled and ready for installation BS EN 12566-1:2016EN 12566-1:2016 (E) 9 3.4 product family group of products in which, for the purpose of evaluation, the selected property(s) is/are similar for all products within the group Note 1
43、 to entry: The definition of family takes into account at least similar shape, equipment, materials and conditions of end use and ensures the minimum hydraulic efficiency and minimum structural behaviour for all the products in the range. Note 2 to entry: The minimum level of performance (hydraulic
44、efficiency and structural behaviour) are given by the test carried out on one model of the family. 4 Product characteristics 4.1 Dimensions 4.1.1 Inlets, outlets and connections Minimum size of nominal diameter of inlet and outlet according to the nominal capacity of equipment is: 100 ND 6 m3; 150 N
45、D 6 m3. For design of outlet devices, see some examples in Annex C (informative). 4.1.2 Ventilation Adequate ventilation of the septic tank and the inlet pipework shall be provided to prevent the accumulation of fermentation gases. 4.1.3 Design Basis Depending on the end use, one or more of the foll
46、owing design criteria may need to be stated. a) Population load; b) Minimum sizing criteria including sludge storage capacity; c) Additional design criteria for domestic wastewater flows from sources such as hotels, restaurants or commercial premises. 4.2 Load bearing capacity Test methods and value
47、s for mechanical characteristics of the materials of the tank, used for calculation of the load bearing capacity of the tank, shall be in accordance with EN 12566-3:2016, Annex D. The septic tank shall resist the loads resulting from handling, installation and use including desludging and maintenanc
