Separately and in combination environmental conditions can represent considerable challenges to the railway sec
39、tor as availability, economy, reputation and safety can be severely affected. Both severe summer and winter conditions occur, and more intense weather is predicted for the future. The intention of this Technical Report is to help reduce technical risks related to environmental conditions. All tests
40、of the different clauses in this Technical Report can be performed either in a climate chamber or on track, if the corresponding test conditions are given. 1 Scope This Technical Report gives guidance for designing rolling stock for its specified ranges of environmental conditions according to EN 50
41、125-1. This guidance covers environmental conditions in Europe. The relevant clauses for the particular vehicle should be chosen and described in the vehicle specification. Depending on the ranges selected, design and/or testing provisions described in this Technical Report should be taken into acco
42、unt. This Technical Report is a collection of existing test descriptions and design guidance based on long lasting experience of operators, test centres and industry. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensabl
43、e for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

44、rms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 environmental conditions physical, chemical or biological conditions external to a product to which it is subject at a certain time SOURCE: EN 50125-1 3.2 winter conditions conditions with temperatu
45、res below freezing point of water, where snow and ice can accumulate on the vehicle 3.3 summer conditions conditions with temperatures above 35 C in addition to intensive solar radiation and hot ballast effect PD CEN/TR 16251:2016CEN/TR 16251:2016 (E) 7 3.4 ice is considered as glaze ice or clear ic
46、e Note 1 to entry: It tends to accumulate rapidly and is very hard and therefore more difficult to remove. Such ice forms when large drops of water strike and spread over a surface whose temperature is below the freezing point. Mechanical components and the windscreen are elements typically tested w
47、ith ice. For the test, a certain thickness of the ice layer is defined. 3.5 dry snow form of precipitation where tiny ice crystals bond together into flakes, which have little to no liquid water content and a particle size of about 20 m MVD (Median Volumetric Diameter) Note 1 to entry: The density o
48、f this snow is about 200 kg/m3and can go up to 350 kg/m3if wind pressed. Note 2 to entry: The snow intensity in kg/m3is defined. 3.6 wet snow form of precipitation where tiny ice crystals bond together into flakes, which have a high liquid content and a particle size of 50 m or more Note 1 to entry:
49、 The density of this snow is about 350 kg/m3to 500 kg/m3. Note 2 to entry: The snow intensity in kg/m3is defined. 3.7 rain precipitation in the form of water drops; both the amount that falls and the actual falling action of the water drops are often called rainfall Note 1 to entry: Rain intensity is measured in mm/min. Note 2 to entry: This standard does not scope with tests concerning water tightness of the vehicle and components. 3.8 condensation precipitation of water vapour on a surface when the surface temperature is lower than the dew point tempera
