This fourth edition cancels and replaces the

20、 third edition (ISO 606:2004), which has been technically revised. It also incorporates Technical Corrigendum ISO 606:2004/Cor. 1:2006. ISO 2015 All rights reserved vBS ISO 606:2015ISO 606:2015(E) Introduction The provisions of this revised International Standard have been established by including s

21、izes of chains used by the majority of countries in the world, and by unifying dimensions, strengths and other data which differed in current national standards, while eliminating those for which it was considered a universal usage had not been established. The whole field of application open to thi

22、s medium of transmission has been covered by the ranges of chains already established. To achieve this, the sizes of 6,35 mm pitch to 76,2 mm pitch inclusive have been duplicated, on the one hand, by the inclusion of chains derived from standards originating and centred around ANSI, and on the other

23、 by chains representing the unification of the principal standards originating in Europe, the two being complementary for the coverage of the widest possible field of application. The ANSI chain reference numbers (25, 35, 40, 50, etc.) are used world-wide and these numbers have now been introduced i

24、nto this International Standard in place of the previous ISO reference numbers (04C, 06C, 08A, 10A, etc.) To assist in cross-referencing the ANSI and previous ISO numbers, details are included in Annex B of this International Standard. The ANSI heavy series of chains (suffix H) are specified in this

25、 International Standard. The ANSI heavy series of chains differs from the ANSI standard series in that thicker plates are used. The ANSI extra heavy series of chains (suffix HE) are now included. The ANSI extra heavy series are dimensionally as the ANSI heavy series (suffix H) but have a higher mini

26、mum ultimate tensile strength. Clause 4 covers specification details for K and M attachments, and extended pin attachments for use with short-pitch transmission roller and bush chains conforming with this International Standard. Clause 5, covering chain sprockets, represents the unification of all t

27、he relevant national standards in the world and includes, in particular, complete tolerances relating to tooth form. The inclusion of the dimensions of the chains specified ensures complete interchangeability of any given size and provides interchangeability of individual links of chains.vi ISO 2015

29、ical transmission of power and allied applications. It covers dimensions, tolerances, length measurement, preloading, minimum tensile strengths and minimum dynamic strength. Although Clause 5 applies to chain sprockets for cycles and motor cycles, this International Standard is not applicable to the

30、ir chains, which are covered by ISO 9633 and ISO 10190, respectively. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

36、the standard ISO chain number given in Tables 1 and 2. The ISO chain numbers in Table 1 are supplemented by a hyphenated suffix 1 for simplex chain, 2 for duplex chain and 3 for triplex chain, for example, 16B-1, 16B-2, 16B-3, 80-1, 80-2, 80-3. Chains 081, 083, 084 and 41 do not follow this procedur

The chains designated in Table 2 are the ANSI heav y and extra heav y series, which are also supplemented by a hyphenated suffix 1 for simplex chain, 2 for duplex chain and 3 for triplex chain, for example, 80H- 1, 80H-2, 80H-3, 80HE-1, 80HE-

43、erformance requirements 3.4.1 General WARNING The test requirements are not to be taken as working loads. These loads could be selected, indirectly, using ISO 10823. The test results shall be invalid if the chain has previously been in service or stressed in any way (other than by preloading in acco

44、rdance with 3.4.3). The tests given in 3.4.2 to 3.4.5 shall only be performed on unused, undamaged chains to determine whether the subject chain complies with the minimum requirements specified in Tables 1 and 2.6 ISO 2015 All rights reservedBS ISO 606:2015ISO 606:2015(E) 3.4.2 Tensile testing 3.4.2

45、.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 various con

46、structions. 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 the chain centreline, in the normal plane of articulation. Annex E (informative) describes methods to consider using in

47、order to avoid an excessive increase in the rate of stress being applied to the chain during the tensile test. 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

48、force at this point shall exceed the minimum tensile strength stated in Tables 1 and 2. Tests in which failures occur adjacent to the shackles shall be disregarded. 3.4.2.3 The tensile test shall be considered as a destructive test. Even though a chain might not visibly fail when subjected to a forc

49、e equivalent to the minimum tensile strength, 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 cranked links, connecting links or chains with attachments, as their tensile strength could be reduced. 3.4.3 Preloading Chains manufactured in conformance with this International Standard shall be preloaded by applying a minimum tensile force equivalent to 30 % of the minimum tensile strength given in Tables 1 and 2. 3.4.4 Length valid
