EN 13595-3:2002 (E) 4 Introduction The only protection a motorcyclist involved in a road traffic accident has against injury is the clothing he or she is wearing at the time. Motorcyclists' clothing is generally worn as an extension of normal clothing, providing protection against ambient conditions of wind, water and cold, but it should also provide some protection from injury in the event of an accident. It is intended not to hinder a rider from controlling his machine. It should be of an acceptable appearance to the wearer. This European Standard is primarily concerned with the protection provided by clothing against injury in accidents. The hazards to which motorcyclists are exposed vary widely depending on the physical environment such as the nature of the road track or mountainside, the climatic environment, the traffic environment, the speed at which the motorcycle is being ridden and the skill of the rider. The number of combinations of possible hazards is very large. Total clothing performance against every identified hazard could be required for each combination. This would be impracticably complicated. Therefore this standard contains the requirements for single characteristics of single items of clothing or simple combinations of garments. This standard is part of a series of standards specifying requirements for particular items of clothing or particular hazards. Further Parts will be issued in due course. 1 Scope This European Standard specifies performance requirements for clothing materials and assembly methodology utilised in the manufacture of professional motorcycle riders jackets, trousers and one-piece and divided suits which are intended to protect the wearer against mechanical injury on metalled road surfaces. It also specifies appropriate test methods whereby conformity against these requirements can be assessed. 2 Normative references This European Standard incorporates by dated reference, provisions from other publications. These normative references are cited at the appropriate places in the text, and the publications are listed hereafter. For a dated reference, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision.

The specimen is gradually stretched into a dome shape by forcing fluid into the chamber at a constant rate. The pressure of the fluid at failure of the specimen and the distension, measured in terms of the height of the dome, are recorded. 4.2 Apparatus and materials 4.2.1A diaphragm bursting test apparatus, similar to EN ISO 13938-1 and EN ISO 13938-2 (exception clamping device); it consists of: 4.2.1.1A rigid chamber filled with fluid and having a circular aperture of diameter equal to, or up to 0,5 mm greater than the diameter of the circular free area (4.2.1.3). 4.2.1.2A circular elastic diaphragm mounted over the aperture in the chamber. The diaphragm and its seal with the chamber shall be able to withstand pressures greater than the burst strength of the material being assessed. The modulus of elasticity of the diaphragm shall be clearly smaller than that of the test specimen. NOTEA value of 5 % of the modulus of the test specimen is recommended. 4.2.1.3A means of clamping the test specimen around its edge, above the diaphragm and over the aperture in the chamber (4.2.1.1), leaving a central circular free area of diameter 113 mm ± 1 mm. The design of the clamping system shall ensure that the test specimen does not slip during the test and shall neither stretch nor compress the central area of the specimen as it is clamped. NOTEThe following has been found to be suitable: six concentric grooves 2,5 mm apart and 1,25 mm deep cut into the lower clamping surface so that the ridges between the grooves have 0,5 mm radius tops. The upper ring is divided into 16 identical segments each of which is clamped against the body with a 25 mm diameter screw. These are tightened with a torque wrench to press the upper ring segments against the lower ring, and to clamp the sample. The complete upper ring has an internal diameter of 113 mm. The upper segments have grooves that interlock with the lower ring ridges. 4.2.1.4A means of pumping additional fluid into the chamber (4.2.1.1) at a constant rate to produce a pressure of up to 2 000 kPa. 4.2.1.5A method of recording the maximum pressure of the fluid in the chamber during the test to the nearest 25 kPa. 4.2.1.6A method of measuring distension of the test specimen, in terms of the height of the dome, in millimetres to the nearest 1 mm. 4.2.2A cutting device, such as a press knife, for cutting test specimens of a suitable size for the clamping system (4.2.1.3). EN 13595-3:2002 (E) 6 4.3 Test specimens 4.3.1For sheet materials, or for each type of seam and slide fastener present in a garment, at least three specimens shall be tested. All combinations of materials beamed in the garment shall be tested, and the test procedure shall accurately replicate the use of the sheet material(s) in finished garments. Where present, exposed row(s) of topstitching thread shall be cut in samples taken from zones 1 and 2, see EN 13595-1:2002, annex C. Use the device (4.2.2) to cut: Option 1: Five individual test specimens of a sufficient size to be clamped firmly in the test machine (4.2.1). Option 2: A single test specimen which is wide and long enough for at least five areas to be clamped and tested in turn. 4.3.2In the case of uncut sheet material, the test positions shall be from a range of locations across the full usable width and length of the material avoiding areas that are within 50 mm of any manufactured edges. NOTEFor a material with a woven structure this should prevent any two specimens containing the same warp or weft threads. Store the test specimens in a standard controlled environment of 23 °C ± 2 °C and 50 % ± 5 % relative humidity for at least 24 h before testing and either carry out the test in this atmosphere or immediately after it has been removed. 4.4 Procedure 4.4.1Ensure that the test machine is reset, with the diaphragm (4.2.1.2) flat and the maximum pressure indicator set to zero. 4.4.2Tightly clamp one of the test specimens into the machine (4.2.1); for strong materials a very high clamping force is necessary whereas with weak thin materials care is required to avoid cutting into the specimen. Delicate materials shall be tested with cotton canvas rings placed against the clamping surfaces of the steel rings. A knitted fabric shall be placed over the elastic diaphragm to support it when testing some mesh fabrics and punched leather. A diaphragm correction is made for whatever materials are used for the diaphragm, or are used to support it (see 4.4.5). Set the distension measuring device (4.2.1.6) to zero. Observe the upper surface of the test specimen and gradually force fluid into the chamber (4.2.1.1) at a constant rate until either the test specimen fails or the specified maximum burst pressure is reached. If the specimen does not fail, the value given in this standard shall be exceeded by at least 50 %. The bursting pressure or 50 % over pressure is recorded. If possible use a fluid flow rate which reaches the desired end point of the test in a time of 30 s ± 10 s. Examine the test specimen and record the direction of the failure. If the failure occurred near to or at the clamped edge of the test specimen or the test specimen slipped in the clamp then discard the results and repeat the test with another test specimen or at another test position. Record the maximum pressure of the fluid to the nearest 25 kPa and the distension of the test specimen to the nearest 1 mm and whether the specimen failed or not. Release fluid from the c
