32、ng and snowboarding helmets1 Scope1.1 This Standard applies to helmets intended to provide head injury risk reduction for recreational alpine skiers and snowboarders. These helmets can also be worn for other non-motorized recreational snow sport activities. This Standard defines the areas of the hea

33、d that are to be protected for impact injuries. It covers the basic performance requirements for shock absorption, helmet stability, and retention system strength as well as marking and labelling requirements.1.2 Visors and detachable accessories are not included in this Standard.1.3 Although a helm

34、et that meets the requirements of this Standard will help reduce the risk of some types of injuries to the head, protection is limited. Users are responsible for participating in a sport within their abilities and taking into account snow and other environmental conditions, which can vary widely. Co

35、mpliance with sport safety rules and applicable responsibility codes can help reduce the risk of personal injury.1.4 In CSA Standards, “shall” is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; “should” is used to express a r

36、ecommendation or that which is advised but not required; “may” is used to express an option or that which is permissible within the limits of the standard; and “can” is used to express possibility or capability. Notes accompanying clauses do not include requirements or alternative requirements; the

37、purpose of a note accompanying a clause is to separate from the text explanatory or informative material. Notes to tables and figures are considered part of the table or figure and may be written as requirements. Annexes are designated normative (mandatory) or informative (non-mandatory) to define t

40、e of the headform plane of the headform corresponding to the human Frankfort horizontal plane.Central vertical axis the line relative to the headform that lies in the median plane of symmetry and that is normal to the basic plane at a point equidistant from the front and back of the headform.Crown t

41、he point where the central vertical axis meets the top of the headform.Drop height the vertical distance from the lowest point (impact point) of the elevated helmet to the impact surface on a drop test apparatus.Fastening system the devices used to connect the components of a helmet.Frankfort horizo

42、ntal plane a plane used in craniometry that is determined from the highest point on the upper margin of the opening of each external auditory canal and the low point on the lower margin of the left orbit and that is used to orient a human skull or head usually so that the plane is horizontal.Frontal

43、 plane the vertical plane that is perpendicular to the median and reference planes and passes through the crown (see Figure 1).Headform a model of the human head that is constructed from rigid materials and on which protective equipment is mounted for performance testing.Helmet a device worn on the

44、head that is intended to reduce the risk of head injury to alpine skiers and snowboarders. Note: Helmets can include a) a shock-attenuating system;b) a retention system; andc) manufacturers attachments.Helmet model a category of helmets that have the same essential characteristics. Note: Essential c

45、haracteristics include materials, dimensions, construction, retention systems, and protective padding.Helmet positioning index (HPI) the vertical distance measured at the median plane, from the front edge of the helmet to the basic plane, when the helmet is placed on the appropriate headform.Median

46、plane the vertical plane that passes through the headform from front to back and divides the headform into right and left halves (see Figure 1).Outer covering (shell) outer material that gives the helmet its form.Z263.1-14Recreational alpine skiing and snowboarding helmetsJune 2014 2014 CSA Group9Pe

47、rmanent marking/warning information that remains legible and cannot be removed in its entirety under conditions of normal use.Rear the point at the posterior intersection of the median and reference planes.Reference plane a construction plane parallel to the basic plane of the headform at a distance

48、 based on the size of the headform.Retention system the system that secures the helmet to the head, when adjusted according to the manufacturers instructions, by passing under the mandible in whole or in part.Support assembly the drop assembly in the monorail system minus the weight of the headform,

49、 ball clamp, ball clamp bolts, and accelerometer.Test area the area on and above the test line, where an impact site is located.Test line the line that defines the boundaries of the test area.Visor an attachment to the helmet intended to reduce sun glare.4 General requirements4.1 Construction requirements Materials4.1.1 DocumentationThe manufacturer shall provide written documentation indicating that the materials used in the construction of the helmet comply with the requirements of Clauses 4.1.2 to
