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
