Test course. The braking tests shall be done on a flat test surface of sufficient length and width, with a maximum 2 per cent gradient, covered with packed snow. The snow surface shall be composed of a hard packed snow base at least 3 cm thick and a surface layer of medium packed and prepared snow about 2 cm thick. The air temperature, measured about one meter above the ground, shall be between ‑2 °C and ‑15 °C; the snow temperature, measured at a depth of about one centimeter, shall be between ‑4 °C and ‑15 °C. It is recommended to avoid direct sunlight, large variations of sunlight or humidity, as well as wind. The snow compaction index measured with a CTI penetrometer1 shall be between 75 and 85.
