27、otorcyclists back protectors are devices worn within or on top of other protective clothing, covering at least a portion of the back as corresponding to one of the three shapes of protectors described in the standard. The performance requirements have been chosen as a best practical compromise betwe

28、en 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 kerb stones. The force levels in the tests do not compare directly with the forces to

29、which riders are exposed in accidents, but experiences have shown that products meeting the requirements of this European Standard reduce the incidence and severity of injuries. This standard accommodates three different typologies of back protector, which are offered to encourage the adoption of ce

30、rtified protection within the different disciplines of motorcycling and the type of rider. These are namely full back, central back and lower back (lumbar) protector, the definition of which are provided in Clause 3. Two performance levels are specified for motorcyclists back protectors against impa

31、cts. These are level 1 for protectors designed to give protection whilst having low ergonomic penalties associated with its use and level 2 for protectors providing an increased protection with respect to level 1. There may be, however, weight and restriction penalties associated with level 2 protec

32、tion. DIN EN 1621-2:2014-05 EN 1621-2:2014(E)5 1 Scope This European Standard specifies the minimum coverage to be provided by motorcyclists back protectors worn by riders in normal traffic situations. The standard contains the requirements for the performance of the protectors under impact and deta

33、ils of the test methods. Requirements for sizing, ergonomic requirements, and requirements for innocuousness, labelling and the provision of information are included. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensabl

34、e for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

41、4 55 4 Requirements 4.1 General Motorcyclists back protectors shall meet an overall requirement that they are safe to use, comfortable to wear and fit for their purpose. Back protectors shall be provided with means of restraint and/or adjustments capable to ensure that the protector is maintained in

42、 position during use. This requirement is not applicable for protectors to be inserted or incorporated into garments. Testing shall be carried out according to 5.2. 4.2 Innocuousness The innocuousness shall comply with the requirements of EN 1621-1. 4.3 Minimum dimensions of zones of protection Moto

43、rcyclists back protectors shall have a minimum zone of protection related to the waist to shoulder measure of the largest user indicated by the marking. The minimum dimensions of the zone of protection shall be determined from Table 1, for the upper value of the size range (see 4.6). DINEN 1621-2:20

45、 refer to the waist to shoulder length (100 %) of the biggest user. The dimensions and position of the zone of protection, relative to the coverage provided by the whole product, shall be given in the information supplied by the manufacturer (see Clause 7). NOTE The minimum dimensions of the zones o

46、f protection are usually marked on the specimens during the testing procedures. 4.4 Impact attenuation When impact protection is tested in accordance with 5.1.6.1 (ambient impact test), 5.1.6.2 (wet impact test) and, if required, 5.1.6.3 (high temperature impact test) and/or 5.1.6.4 (low temperature

47、 impact test), the transmitted force shall conform to the values in Table 2. Level 1 or 2 cannot be awarded unless such level is achieved under all of the claimed test conditions.
