(b)Pressure cycle between ≤ 2,0 MPa and ≥ 1,25 times nominal working pressure at a temperature ≥ 85 °C and a relative humidity ≥ 95 per cent, for 1,5 times the number of filling cycles calculated in accordance with section 2.7.6.;
(c)Stabilise at ambient conditions;
(d)Condition the container and test fluid to a temperature ≤ – 40 °C as measured on the container surface and in the fluid;
(e)Pressure cycle at ≤ – 40 °C between ≤ 2,0 MPa and ≥ nominal working pressure, for 1,5 times the number of filling cycles calculated in accordance with section 2.7.6.;
