WARNING The United Kingdom, as a member of CEN, is obliged to publish EN 1621-2:2003 as a British Standard. However, attention is drawn to the fact that during the development of this European Standard, the United Kingdom consistently voted against its approval as a European Standard. The reason for this disapproval is that during discussion of this standard by BSI Committee PH/3/9, which mirrors the work of CEN Committee TC162, WG9, several UK experts expressed the opinion that the transmitted force levels given as requirements in this EN are too high. BSI will assume no liability whatsoever for the failure on the part of any user of this standard to consider this aspect.

About 13% of motorcyclists injured in road accidents have an injury to this back region. However, only 0,8% of the injured riders suffer a fracture of the spine and less than 0,2% of injured riders have a serious back injury resulting in neurological damage. These serious injures are usually caused by axial forces due to blows on the head, or bending and twisting forces on the back caused by blows to the shoulders, hips and other parts of the body. Back protectors do not provide protection from these forces. The majority of the more minor injuries are bruises and strains caused by direct blows, and back protectors can provide some protection against these. The scapula is often injured (1,3%), protection should extend to cover this area. 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 kerb stones. 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 reduce the incidence and severity of injuries. Motorcyclists' back protectors are sometimes combined with a product such as a body belt or lumbar support designed to give support to the lower back in normal riding. These elements, within their limited size, can also provide some impact protection, in this case they are to be called 'lumbar protectors' and are also covered by this standard.

The standard contains the requirements for the performance of the protectors under impact and details of the test methods. Requirements for sizing, ergonomic requirements, and requirements for innocuousness, labelling and the provision of information are included. The provision of this European Standard may not fully cover the needs of particular protectors (e.g. inflatable protector or other types of protector). 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed below. In the case of dated references, subsequent amendments to, or revisions of, any of these publications, apply to this European Standard only when incorporated into it by amendment or revision. In the case of undated references the latest edition of the publications referred to applies (including amendments). EN 340, Protective clothing — General requirements. EN 1621-1:1997, Motorcyclists' protective clothing against mechanical impact — Part 1: Requirements and test methods for impact protectors. ISO 6487, Road Vehicles — Measurement techniques in impact tests – Instrumentation. ISO 7000, Graphical symbols for use on equipment — Index and synopsis. 3 Terms and definitions For the purposes of this European Standard, the following terms and definitions apply: 3.1 general 3.1.1 motorcyclist's back protectors motorcyclist’s back protectors are specific devices worn on the back that are intended to reduce the severity of injuries caused by impacts 3.1.2 motorcyclist's lumbar protector motorcyclist’s back protector with dimensions limited to cover the lumbar region; intended to reduce the severity of injuries caused by impacts 3.1.3 zone of protection the zone of protection is a specific area of the protective equipment that is intended to provide protection and this area is subject to specific testing NOTE The minimum dimensions of the zones of protection will normally be marked on test specimens during the test procedures.
