5.1.2 Stability and strength calculations shall be carried out in accordance with EN 1915-2. 5.1.3 For stairs to be moved on public roadways, the dimensions, laden mass and other characteristics shall meet all applicable government regulations when in fully retracted position. NOTE Applicable government regulations depend on the airport of use. 5.1.4 Passenger stairs shall have an upper (main) platform and, where the number of risers exceeds 18, an intermediate platform shall be provided at least after every 18 risers. The number of risers shall not normally exceed 40. SIST EN 12312-1:2013
