The w
13、ork of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-govern
14、mental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The
15、 main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.
16、 Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 10190 was prepared by Technical Committee ISO/TC 100, Chains and chain sprockets for power trans
17、mission and conveyors. This second edition cancels and replaces the first edition (ISO 10190:1992), which has been technically revised. BS ISO 10190:2008ISO 10190:2008(E) ISO 2008 All rights reserved vIntroduction This International Standard has been produced to meet the increasing demands for diffe
18、rent chains suitable for motorcycle applications. Precision roller chains specified in IS0 606 do not necessarily have the required performance for motorcycle use. The values given in this International Standard are derived from values in Imperial units; the original values are given in Annex B for
19、reference purposes. BS ISO 10190:2008BS ISO 10190:2008INTERNATIONAL STANDARD ISO 10190:2008(E) ISO 2008 All rights reserved 1Motorcycle chains Characteristics and test methods 1 Scope This International Standard specifies the dimensions and mechanical properties of roller and bush chains (together w
20、ith details of associated chain sprockets), in the range 6,35 mm to 19,05 mm pitch, for use in motorcycle applications. These chains are suitable for external drives (e.g. rear drives). It covers dimensions, tolerances, length measurement, preloading, minimum tensile strength and minimum dynamic str
21、ength. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies.

25、nsions Chains shall conform to the dimensions shown in Figure 3 and given in Table 1. NOTE Maximum and minimum dimensions are specified to ensure interchangeability of chains produced by different makers over the same sprockets. They are not the actual manufacturing tolerances. 3.4 Performance requi
26、rements and tests 3.4.1 General The tests given in 3.4.2 to 3.4.5 shall be performed to determine whether the subject chain conforms to the minimum requirements specified in Table 1. WARNING The test requirements specified do not relate to actual chain applications; therefore, neither the values spe
27、cified nor the test results should be taken as working loads. The test results will be invalid if the chain has previously been in service or stressed in any way (other than by preloading in accordance with 3.4.3). BS ISO 10190:2008ISO 10190:2008(E) ISO 2008 All rights reserved 33.4.2 Tensile testin
28、g 3.4.2.1 The minimum tensile strength is that value which shall be exceeded when a tensile force is applied to a sample tested to destruction in accordance with 3.4.2.2. NOTE This minimum tensile strength is not a working load, but is intended primarily as a comparative figure between chains of var
29、ious constructions. For chain application information, the chain manufacturers or their published chain data should be consulted. 3.4.2.2 Apply a tensile force slowly to the ends of a chain length containing at least five free pitches by means of fixtures permitting free movement on both sides of th
30、e chain centreline, in the normal plane of articulation. Failure shall be considered to have occurred at the first point where increasing extension is no longer accompanied by increasing force, i.e. the summit of the force/extension diagram. The force at this point shall be equal to or exceed the mi
31、nimum tensile strength stated in Table 1. Tests in which failures occur adjacent to the fixtures shall be disregarded. 3.4.2.3 The tensile test shall be considered as a destructive test. NOTE Even though a chain might not visibly fail when subjected to a force equivalent to the minimum tensile stren
32、gth, it will have been stressed beyond the yield point and will be unfit for service. 3.4.2.4 These requirements do not apply to connecting links. 3.4.3 Preloading The chains shall be preloaded by applying a minimum tensile force equivalent to at least 30 % of the minimum tensile strength given in T
33、able 1. 3.4.4 Length validation Chain length validation shall be carried out after preloading but before lubrication. The standard length for measurement shall be a minimum of 610 mm and the chain shall terminate with an inner link at each end. The chain shall be supported throughout its entire leng
34、th and the measuring force given in Table 1 shall be applied. The measured length shall be the nominal length 0,250+%. 3.4.5 Dynamic testing Chains shall meet the requirements of the conformity test as described in ISO 15654, using the minimum dynamic strength values shown in Table 1 for the particu
35、lar chain. The maximum test force to be used shall be determined as shown in Annex C. 3.5 Marking The chain shall be marked with the manufacturers name or trademark, and the chain number quoted in Table 1 should be marked on the chain. 4 Chain sprockets To ensure interchangeability between motorcycl
36、e chains and their respective chain sprockets, the sprockets for external drives shall conform to the dimensions specified in ISO 606 or alternatively to those dimensions specified in Annex A of this International Standard.
