ISO/TC 100 - Chains and chain sprockets for power transmission and conveyors

ISO 15654:2015 specifies an axial force fatigue test method for transmission roller chains and leaf chains. The tests being of the fluctuating tension type, carried out at room temperature in air, with the force applied along the longitudinal axis of the chain. It also specifies procedures for statistically analysing the test results and gives formats and elements for presenting the results of fatigue tests and analyses.

ISO 4347:2015 specifies the characteristics of chains used for general lifting purposes, together with the rim profiles of sheaves and the chain attachment ends of clevises. It gives dimensions, limits for interchangeability, length measurement, preloading, minimum tensile strengths and minimum dynamic strengths.

ISO 606:2015 specifies the characteristics of short-pitch precision roller and bush chains with associated sprockets suitable for the mechanical 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 their chains, which are covered by ISO 9633 and ISO 10190, respectively.

ISO 10190:2008 specifies the dimensions and mechanical properties of roller and bush chains (together with 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). ISO 10190:2008 covers dimensions, tolerances, length measurement, preloading, minimum tensile strength and minimum dynamic strength.

ISO 1275.2006 specifies requirements for double-pitch precision roller chains suitable for the mechanical transmission of power and for conveyors, together with those for their associated sprockets. It covers dimensions, tolerances, length measurement, preloading and minimum tensile strengths. These double-pitch chains have been derived from some of the short-pitch transmission precision roller chains covered by ISO 606 having certain common dimensions but of double the pitch. The chains are intended for use under less onerous conditions with respect to speed and power transmitted than are the base chains from which they are derived. ISO 1275.2006 primarily applies to sprockets with 5 to 75 teeth inclusive (with intermediate numbers of teeth 5 and a half to 74 and a half inclusive). The preferred numbers of teeth are 7, 9, 10, 11, 13, 19, 27, 38 and 57.

ISO 10823:2004 gives guidelines for the selection of chain drives, composed of a roller chain and sprockets conformant with ISO 606, for industrial applications. The selection procedures and chain ratings it describes provide for roller chain drives operating under specified conditions with a life expectancy of approximately 15 000 h. Owing to the wide variations in loading characteristics, environmental conditions and achieved maintenance, it is desirable that the supplier of the chains and sprockets be consulted to ensure that the performance of the product meets the requirements specified both by the user and by this International Standard.

ISO 6971:2002 specifies the characteristics of cranked-link drag chains of welded construction suitable for conveying bulk materials, together with associated attachments and chain sprockets. The chain dimensions specified in ISO 6971:2002 ensure interchangeability of both complete chains and individual links for repair purposes. ISO 6971:2002 is applicable to sprockets with between 5 and 20 teeth. Specifications are also given for five types of attachment for use with the conveyor chains conforming to ISO 6971:2002.

ISO 6972:2002 specifies the characteristics of cranked-link mill chains of welded construction suitable for conveying bulk materials, together with associated attachments and chain sprockets. The chain dimensions specified in ISO 6972:2002 ensure interchangeability of both complete chains and individual links for repair purposes. ISO 6972:2002 is applicable to sprockets with between 5 and 36 teeth. Specifications are also given for eight types of attachment for use with the conveyor chains conforming to ISO 6972:2002.
