1、CAN/CSA-Dll3.2-M89 Cycling Helmets A National Standard of Canada (Reaffirmed 2004) The Canadian Standards Association (CSA), under whose auspices this National Standard has been pro- duced, was chartered in 191 9 and accredited by the Standards Council of Canada to the National Standards system in 1

2、973. It is a not-for-profit, nonstatutory, voluntary membership association engaged in stand- ards development and certification activities. CSA standards reflect a national consensus of produc- ers and users - including manufacturers, consumers, re ta ilers, u n ions and p ro fess io n a I organ iz

3、a t io n s, an d governmental agencies. The standards are used widely by industry and commerce and often adopted by mu- nicipal, provincial, and federal governments in their regulations, particularly in the fields of health, safety, building and construction, and the environment. individuals, compan

4、ies, and associations across Can- ada indicate their support for CSA s standards develop- ment by volunteering their time and skills to CSA Committee work and supporting the Associations ob- jectives through sustaining memberships. The more than 7000 committee volunteers and the 2000 sustain- ing me

In addition to its head office and laboratory complex in Etobicoke, CSA has regional branch offices in major centres across Cana

General Construction Requirements 4.1 Materials 4.1 .I All materials used in the fabrication of helmets should be known to be suitable for use in the design of protective cycling helmets. The materials should not undergo apprecia

29、ble alteration due to aging or normal use, such as exposure to sun, extremes of temperature, and rain. 4.1.2 For those parts of the helmet coming into contact with the wearers skin, the manufacturer should use materials that will not cause irritation or disease. For materials not in general use, med

30、ical advice as to their suitability should be sought before adoption. 4.2 HeImet Assembly 4.2.1 There shall be no rigid protrusions on the inner surface of the helmet liner. 4.2.2 Below the helmet reference plane, irregularities in the outer surface of the helmet shall be smoothly fai red. 4.3 Reten

31、tion System 4.3.1 The retention system shall be constructed such that when properly fastened and adjusted, the helmet will not readily dislodge from, or shift on the head. 4.3.2 The minimum width of the retention system straps shall be 12 mm. 4.4 Visors Visors shall be removeable and are not covered

The retention system s

33、hall not release and the distance “d“ in Figure 3 shall be observed for conformance with Clause 5.3.1 and recorded. This shall be done using four helmets, each conditioned under one of the requirements of Clauses 6.3(a), (b), (c), and (d). 6.5.2 . 3 During testing at low temperature as in Clause 6.3

34、(b), the fastening device (ie, clip) for retention shall be cycled five times (ie, opened and closed). 6.5.2.4 Stability Test (a) The posterior neck piece of the headform shall be attached on an appropriately sized headform (see Figure 1). The headform shall then be secured to a rigid fixture. (b) T

35、he helmet shall be positioned and secured onto the headform in accordance with the manufacturers instructions. (c) A hook mechanism shall be attached to the front lower edge of the helmet. A force of 250 N shall then be applied upwards at a constant rate, in the sagittal plane of the headform tangen

36、tially to the helmet. This force shall be maintained for a minimum period of 5 s. If the helmet moves more than 10 mm on the headform, the force shall be applied for a further 5 s. (d) This procedure shall be repeated with the hook mechanism attached to the rear edge of the he1 met. (e) The change i

37、n the angle subtended by the basic plane and a plane passing through point Q, tangent to the edge of the helmet where the force is being applied, shall be measured. 7. Labels and Marking 7.1 Labels 7.1 .I All cycling helmets offered for sale shall have a label or tag bearing safety information in bo

38、th English and French. The information label should contain statements similar to the following: (a) This helmet is designed solely for use by cyclists. (b) No helmet can protect the wearer against all possible impacts. For maximum protection this helmet shall be fitted properly and adjusted securel

39、y. 7.1.2 The manufacturer shall supply a label or tag giving instructions on how to fit the helmet properly. 7.2 Markings Ail helmets offered for sale shall bear the following permanent markings: (a) the manufacturers identity; (6) the helmet model identity; (c) the helmet size or size range; (d) th

40、e date of manufacture (year/month); (e) The following warning-“This helmet is designed to absorb the shock of an impact by partial destruction of the shell and liner. Following an accident, this damage may not be visible to the eye. Therefore, if subjected to a severe blow, the helmet should be dest

41、royed“. (f) The following warning-“This helmet should not be painted nor should decals be applied unless they are approved by the manufacturer, as they may weaken the shell structure“. (9) The approved list of cleaning agents should be included with the maintenance instructions. Cycling Helmets May

45、ause 6.4.1 (d), (e), and (f) for specifications of the anvils and rigid mount). The centre of each impact site shall be selected at any point within the area above the test line and separated from the centres of the other impact sites by a surface distance of not less than one-fourth of the maximum

46、circumference of the helmet. 8.2.2.2 If there are mechanical fasteners in the test area, at least one of these shaIl be impacted. 8.2.2.3 There shall be at least one impact at the front, one impact at the rear, and one impact on one side of the helmet. The fourth impact site shall be chosen at the d

47、iscretion of the testing facility. 8.2.2.4 In each series of tests, there shall be at least two impacts of 5.7 m/s on the flat anvil and one impact of 4.7 m/s on the cylindrical anvil. 8.2.3 Test Criteria (See Table 1) When the helmet is tested in accordance with Clause 6.4.2 using the (a) flat anvi
