code for the area more than 1 m from the building to which the buried piping system is connected;  D:
code for the area under and within 1 m from the building where the pipes and the fittings are buried in ground and are connected to the soil and waste discharge system of the building NOTE In code D application areas, the existence of hot water discharge in addition to the external forces from the surroundings is usual.

No breakage or leakage shall occur during the one-year conditioning period. After conditioning in one year the pipe shall be tested on ring stiffness in accordance EN ISO 9969 and ring flexibility in accordance with !EN ISO 13968" and meet the relevant requirements in Table 6. Test pieces cut from the pipe shall be subjected to tensile testing in accordance with ISO 6259-3 at (23 ± 2) °C with the following amendments:  5.1.2: test piece type 2 for wall thicknesses < 5 mm and type 1 for wall thicknesses ≥ 5 mm.  Clause 7: test speed 10 mm/min for both type 1 and type 2 test pieces. The test piece shall be prepared by machining. Both tensile strength and elongation at break shall be controlled on five test pieces and the test result shall be calculated as the mean value of the five individual tests. When test results after one year conditioning according to above specified parameters are compared with test results on test pieces taken from non-conditioned pipe, the tensile strength and elongation at break shall not be reduced by more than 25 % after the conditioning.
