4 Functional sizes 4.1 General The drawings are examples only and products need not correspond. However, dimensions are binding. The rungs and steps of a ladder shall be equally spaced with a tolerance of ± 2 mm. The inner width b1 shall be measured at the upper edge of the shortest rung/step. The outside width b2 shall be measured at the lower end of the ladder. In addition to tests on the complete ladder sections which can be dismantled without the use of tools shall conform, section by section, with the requirements
