19、 the vertical plane; b) all wheels of the caravan, including the jockey wheel, rest on the supporting surface, and its interior floor is horizontal; c) roof vents, doors, and windows are closed; retractable steps are retracted; d) the longitudinal median plane of the caravan is that defined in ISO 6
20、12, clause 5; e) the mass of the caravan, at the moment of measurement, is the maximum authorized total mass (see 5.1.4.2), the load being distributed according to the manufacturers instructions; f) the tyres are inflated to the pressure corresponding to the maximum authorized total mass (see 5.1.4.
