EN 13484:2001 (E)3ForewordThis draft European Standard has been prepared by Technical Committee CEN/TC 158 "Headprotection", the secretariat of which is held by BSI.This European Standard shall be given the status of a national standard, either by publication ofan identical text or by endorsement, at the latest by May 2002, and conflicting national standardsshall be withdrawn at the latest by May 2002.This European Standard has been prepared under a mandate given to CEN by the EuropeanCommission and the European Free Trade Association, and supports essential requirements ofEU Directive(s).For relationship with EU Directive(s), see informative annex ZA, which is an integral part of thisstandard.Annex A is informative.According to the CEN/CENELEC Internal Regulations, the national standards organizations ofthe following countries are bound to implement this European Standard: Austria, Belgium, CzechRepublic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg,Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom.SIST EN 13484:2002
EN 13484:2001 (E)4IntroductionThe intention of helmets is to reduce the risk of injury to the skull and part of the head surroundedby the helmet.The protection given by a helmet depends on the circumstances of the accident and wearing ahelmet cannot always prevent death or long term disability.In this standard, the concept of optimum level of protection has been taken into account. Thismeans that the protection efficiency is as high as possible, without decreasing the wearer’sacceptance to the extent that she/he will not wear it, because of discomfort caused by the increaseof the mass and dimensions.A proportion of the energy of an impact is absorbed by the helmet, thereby reducing the force of theblow sustained by the head. The structure of the helmet can be damaged in absorbing this energyand any helmet that sustains a severe blow should be replaced even if damage is not apparent.To achieve the performance of which it is capable, and to ensure stability on the head, a helmetshould be as closely fitting as possible consistent with comfort. In use it is essential that the helmetis securely fastened, with any chin strap under proper tension at all times.SIST EN 13484:2002

Materials shall not be used which are known to cause skin disorders. Testingaccording to 5.1.4.2Construction4.2.1GeneralThe helmet normally consists of means of absorbing impact energy and means of retaining thehelmet on the head even in an accident.The helmet shall be so designed and shaped that parts of it (visor, rivets, ventilators, edges,fastening device and the like) are not likely to injure the user in normal use.NOTE
Helmets should- have low weight;- be easy to put on and take off;- be usable with spectacles;- not significantly interfere with the ability of the user to hear;- have good durability and withstand normal handling;- permit cleaning.Testing in accordance with 5.14.2.2Retention system4.2.2.1GeneralMeans shall be provided for retaining the helmet on the wearer's head. All parts of the retentionsystem shall be securely attached to the system or to the helmet.NOTE 1
It is recommended that the opening mechanism be marked with red or orange colour.NOTE 2
The colour of any part of the retention system should not be green,as green is used for helmets withan emergency release system.Testing in accordance with 5.1.4.2.2.2Chin strapsThe chin strap shall not include a chin cup.Any chin strap shall be not less than 15 mm wide.Chin straps can be fitted with means of enhancing comfort for the wearer.Testing in accordance with 5.1.SIST EN 13484:2002

In this test, slippage of the fastening device may be measured and recorded separately from othercontributions to the extension, but this is for information only and is not subject to separate requirement.4.6.2EffectivenessWhen tested in accordance with 5.10 the helmet, selected to be of appropriate size, shall not comeoff the headform.4.7DurabilityAfter being tested the helmet shall not show damage that would cause an additional injury to thewearer (sharp edges, points, etc.).

Calculate and record themean value in grams rounded off to the nearest 10 g stating the size of the helmet.5.5Helmet positioning and determination of field of vision and area of coveragePlace the helmet on a headform of largest appropriate size and complying with the requirements forshape in EN 960. Apply a load of 50 N on the crown of the helmet in order to adjust the helmet onthe headform. Ascertain that the vertical median plane of the helmet coincides with the verticalmedian plane of the headform.Adjust the helmet on the headform according to the manufacturer's instructions. In that positiondetermine if the helmet complies with the requirements for field of vision in 4.2.3 and the extent ofcoverage in 4.3.To determine whether the helmet complies with the requirements for field of vision in 4.2.3, the testhouse shall select the size it considers likely to yield the least favourable result for the helmet type.If any of the requirements in 4.2.3 and 4.3 are not fulfilled, adjust the helmet on the headform aslittle as possible to satisfy both requirements.In that position draw the following line(s) on the helmet:SIST EN 13484:2002
