EN 13595-3:2002 (E) 4 Introduction The only protection a motorcyclist involved in a road traffic accident ha
21、s 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.
22、 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 d
23、epending 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 per
24、formance 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
25、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 motorcyc
26、le 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 Sta

EN ISO 13938-2, Textiles - Bursting properties of fabrics - Part 2: Pneumatic method for determination of
30、 bursting strength and bursting distension (ISO 13938-2:1999). 3 Terms and definitions For the purpose of this European Standard, the following term and definition apply. 3.1 professional rider person who is employed to provide or contracts to perform for reward, the services requiring the riding of
31、 a motorcycle EN 13595-3:2002 (E) 5 Examples are: a) the delivery of letters, packets or other small freight; b) the transport of passengers by motorcycle; c) emergency medical treatment; d) vehicle breakdown support. 4 Determination of burst strength 4.1 Principle A circular test specimen and an un
32、derlying elastic diaphragm are clamped around their edges over the top of a chamber. 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
33、 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 great
34、er 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 elas
35、ticity 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
36、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 gr
37、ooves 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
38、 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 constan
39、t 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.
40、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
41、. 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,
42、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 s
43、heet 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 wef
44、t 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, wi
45、th 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. De
46、licate 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 u
47、sed 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 bu
48、rst 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
49、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
