EN 1621-3:2018 (E) 4 European foreword This document (EN 1621-3:2018) has been prepared by Technical Committee CEN/TC 162 “Protective clothing including hand and arm protection and lifejackets”, the secretariat of which is held by DIN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by June 2019, and conflicting national standards shall be withdrawn at the latest by June 2019. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN shall not be held responsible for identifying any or all such patent rights. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive 89/686/EEC and Regulation (EU) 2016/425. EN 1621 consists of the following parts, under the general title “Motorcyclists’ protective clothing against mechanical impact”: — Part 1: Motorcyclists' limb joint impact protectors - Requirements and test methods — Part 2: Motorcyclists' back protectors - Requirements and test methods — Part 3: Motorcyclists' chest protectors - Requirements and test methods — Part 4: Motorcyclists' inflatable protectors - Requirements and test methods According to the CEN-CENELEC Internal Regulations, the national standards organisations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom.

EN 1621-3:2018 (E) 5 Introduction Motorcyclists' chest protectors are devices worn within or on top of other protective clothing, covering the chest of the rider. The performance requirements have been chosen as a best practical compromise between protection, comfort, and ergonomic requirements. Protectors that are too stiff or heavy will not be worn. The test methods are designed to provide information on protection against impacts against edges such as kerbstones or corner of car roofs. The force levels in the tests do not compare directly with the forces to which riders are exposed in accidents, but experiences have shown that products meeting the requirements of this European Standard may reduce the incidence and severity of injuries. This standard accommodates two different typologies of protector, which are offered to encourage the adoption of certified protection within the different disciplines of motorcycling and the type of rider. These are namely the divided and full protector, the definition of which are provided in Clause 3. Two performance levels are specified for motorcyclists' chest protectors against impacts. These are level 1 for soft protectors which fulfil only the force transmission requirements, and level 2 for more rigid protectors which fulfil both the force transmission and force distribution requirements. There may be, however, weight and restriction penalties associated with providing level 2 protection. SIST EN 1621-3:2019



EN 1621-3:2018 (E) 6 1 Scope This document specifies the minimum coverage to be provided by motorcyclists’ chest protectors. The standard contains the requirements for the performance of the protectors under impact and details of the test methods, dimensions, ergonomic requirements, and requirements for innocuousness, labelling and the provision of information. This document defines a product which provides limited protection against mechanical impacts and falls on the chest. If the product is only intended to protect against lofted stones (commonly used in off-road riding) then EN 14021 will be used. Where a product is intended to protect against mechanical impacts and lofted stones this document will be used. 2 Normative references The following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document.

Chest protectors shall be provided with means of restraint and/or adjustments capable to ensure that the protector is maintained in position during use. This requirement is not applicable for protectors to be inserted or incorporated into garments. Testing shall be carried out according to 5.7. 4.2 Innocuousness The innocuousness shall comply with the requirements of EN 1621-1. 4.3 Minimum dimensions of zones of protection 4.3.1 General
Motorcyclists’ chest protectors shall provide a minimum zone of protection. For full chest protectors this is defined in Figure 1a, and for divided chest protectors in Figure 1b. Dimensions are provided in Table 1.

However, for ergonomic reasons, in certain cases the type B protectors may be unsuitable. In such cases, the alternative type A protectors can be chosen by the user. 4.3.2 Levels of protection — Level 1 Protectors: Protectors made of soft material providing impact attenuation but not impact distribution. — Level 2 Protection: Protectors made of more rigid material providing impact attenuation and impact distribution. NOTE Level 2 protectors give improved protection; however, they can be heavier and have restriction penalties associated. 4.4 Impact Attenuation This requirement is applicable to level 1 and level 2 protectors. When impact attenuation is tested in accordance to 6.3 with samples conditioned to 6.5.1 (ambient impact test), and repeated with samples conditioned to 6.5.2 (wet impact test) and, if required, 6.5.3 (high temperature impact test) and/or 6.5.4 (low temperature impact test), the transmitted force shall record an average peak force
¶ 18 kN and no single value shall exceed 24 kN. The average for each group of impacts conducted from 6.5.1 to 6.5.4 and the individual peak forces are reported. After each test, there shall be no fragmentation of the sample and no sharp edges shall be formed. However, formation of cracks and loss of soft debris is permissible. 4.5 Impact Distribution This requirement is applicable to level 2 protectors only. When impact distribution is tested in accordance to 6.4 with samples condition to 6.5.1 (ambient impact test), and, if required, 6.5.3 (high temperature impact test) a
