EN 15152:2007 (E) 4 1 Scope This European Standard specifies the functional requirements for cab windscreens of high speed trains including
19、 testing and conformity assessment. The same requirements can be applied to the windscreens of other types of rolling stock if some of the performance criteria are adjusted to suit the application. Such changes should be based on national standards or infrastructure controllers regulations where the
20、y exist. This European Standard does not specify all interfaces between the windscreen and the vehicle. This European Standard does not apply to the renewal of windscreens of high speed rolling stock already in operation. 2 Normative references The following referenced documents are indispensable fo

32、face 4 Functional requirements 4.1 General The windscreen shall be able to withstand the normal operational conditions including environmental conditions according to EN 50125-1. The peripheral area may be deliberately obscured (in whole or in part) e.g. by silk-screen printing for any of the follow
33、ing reasons: aesthetic purposes; elimination of distracting items from the drivers field of vision; for windscreens that are glued into position, to protect the glued area, if necessary, from the effect of Ultra-Violet (UV) radiation. In this case, the obscuration shall not permit more than 0,1 % of
34、 incident UV light to reach the glued area. 4.2 Specific performance requirements 4.2.1 General The windscreen has three optical areas: A: primary vision area; B: secondary vision area; C: peripheral area. The extent of these areas is described in 5.2. 4.2.2 Secondary image separation In the case of
35、 more than one secondary image, a maximum of one secondary image is to be evaluated. The image to be considered is that which appears brightest to an observer looking through the windscreen from the driving position. The secondary image separation shall not exceed: maximum 15 min of arc in area A; m
36、aximum 25 min of arc in area B. EN 15152:2007 (E) 7 See 6.2.1 for the test method. 4.2.3 Optical distortion The limit of optical distortion shall be: maximum 2 min of arc in area A; maximum 6 min of arc in area B. See 6.2.2 for the test method. 4.2.4 Haze The maximum value of haze shall be 2,5 % for
37、 a new windscreen. See 6.2.3 for the test method. 4.2.5 Luminous transmittance The minimum value of luminous transmittance for areas A and B shall be: 65 % when viewed horizontally through the windscreen in its mounted position. See 6.2.4 for the test method. 4.2.6 Chromaticity The windscreen shall
38、not affect the colour of light transmitted through the windscreen to an extent that will cause the driver to misread signals. The minimum requirement for this European Standard is that the windscreen shall not cause a colour shift so that a red signal lamp observed to lie within coordinates of the C
39、IE 1931 Colour Diagram as illustrated in CIE S 004 (0,700; 0,295), (0,705; 0,295), (0,720; 0,280), (0,715; 0,280) would appear, when viewed through the windscreen, to lie outside a zone with co-ordinates (0,680; 0,305), (0,695; 0,305), (0,730; 0,270), (0,715; 0,270). See 6.2.5 for the test method. I
40、f an additional requirement to support recognition of yellow signals is specified for the train to which the windscreen is to be fitted, then the further criterion shall be as follows: The windscreen shall not cause a colour shift such that a yellow signal lamp observed to lie within co-ordinates (0
41、,590; 0,410),(0,575; 0,410),(0,612; 0,382),(0,618; 0,382), would appear, when viewed through the windscreen, to lie outside a zone with co-ordinates (0,560; 0,440),(0,546; 0,426),(0,612; 0,382),(0,618; 0,382). 4.2.7 Impacts The windscreen shall be able to resist the impact of an object accidentally
42、or deliberately hitting the windscreen. This shall be demonstrated by the test requirements as defined in 6.2.6. 4.2.8 Residual visibility after breakage The windscreen, when impacted or cracked under requirement 4.2.7, shall remain in its position and have sufficient residual visibility for the tra
43、in to be driven to a place of safety. EN 15152:2007 (E) 8 4.2.9 Spalling The driver shall be protected from spalling. This shall be demonstrated by the test requirements as defined in 6.2.7. 4.2.10 Resistance against abrasion The interior and exterior surface materials of a windscreen shall be able
44、to withstand abrasion. The resulting change of haze after abrasion shall not exceed 2 % for the test of the outside surface and 8 % for the test of the inside surface. The test requirements are defined in 6.2.8. 4.2.11 Resistance against fire The design of the windscreen shall be such as to minimise
45、 the risk of combustion or production of toxic smoke. If the relevant fire protection requirements of applicable European or national standards are not technically achievable with functionally suitable materials, then it is acceptable to use state-of-art products until and unless a suitable complian
46、t material is developed. The supplier shall demonstrate to a responsible certification body that any such products used are indeed suitable in accordance with this clause. 4.2.12 Resistance to repeated impact from small particles (gravelling) The risk of this type of damage will vary according to tr
47、ain speed, the aerodynamic conditions on the exterior of the driving cab and the construction of the infrastructure on which the train will operate. It is therefore the choice of the customer whether to demand that resistance to gravelling is demonstrated. If a resistance to gravelling is required,
48、then the test requirements shall be as defined in 6.2.9. 4.3 Additional requirements 4.3.1 Appearance 4.3.1.1 General Appearance defects (blemishes) are specifically characteristics of one of the following elements of the windscreen: glass; interlayer; anti-spall layer; assembly; handling. To ensure
49、 an acceptable quality of vision to the driver, the number and size of such defects shall not exceed the limits listed in 4.3.1.3. See 6.3.1 for the test methods. EN 15152:2007 (E) 9 4.3.1.2 Definition and classification of defects Defects are divided into three categories according to their importance: negligible; minor; major. Table 1 is used to classify defects according to their characteristics. EN 15152:2007 (E) 10 Table 1 Classification of defects Negligible Minor Major Point defects Bubble: Ai
