This is checked by visual inspection.4.2 MaterialsNo parts of the ski goggle which are in contact with the wearer shall be made of materials that are known to causeirritation, allergic or toxic reaction in a normal state of health amongst a significant proportion of users.This is checked by the inspection of the information supplied by the manufacturer.NOTERare or idiosyncratic reaction to any material may occur and may indicate the need for the individual to avoidparticular types of material. Adverse skin reaction may be due to other causes, e.g. excessive contact pressure.4.3 Sit and fitSki goggles shall sit reliably when used as intended and adapted to the contours of the face. The surfaces incontact with the face shall be made of soft flexible material. The head strap shall be designed to be flexible oradjustable and sit securely on the back of the head or the helmet. The head strap assembly shall withstand anystress which occurs during proper use without tearing or being permanently deformed. This is checked by visualinspection.

Page 5EN 174:20014.4 VentilationDesign measures shall ensure that the inside of the ski goggles is well ventilated during skiing.This is checked by visual inspection.NOTEThe necessary rate of air exchange and the design of the ventilation openings depend heavily on the weather, styleof skiing and the individual conditions (e.g. sweating), which means that generally applicable requirements cannot be stipulated.5 Other requirements5.1 Optical requirements5.1.1 Field of visionThe size of the field of vision is defined in conjunction with the head-form as given in clause 17 of EN 168:2001.Ski goggles shall exhibit a minimum field of vision defined by the two ellipses in Figure 1 when placed and centeredat a distance of 25 mm from the surface of the eyes of the head-form. The horizontal axis shall be parallel to and0,7 mm below the height of the line connecting the centres of the two eyes. The plane of the ellipses shall beparallel to the back flat portion of the head-form.The horizontal length of the ellipses shall be of 32 mm, the vertical width of the ellipses shall be of 25 mm. Thecentre distance of the two ellipses shall be d = c + 20 mm, where c is the pupillary distance. The pupillary distanceis 64 mm, if not specified differently by the manufacturer.The test shall be carried out in accordance with 6.2.Dimensions in millimetresFigure 1 - Definition of the field of vision5.1.2 Lens requirementsThe lens requirements are summarised in Tables 1 and 2.SIST EN 174:2001
