International Standards are drafted in accordance with the rules given in the ISO/lEC Directives, Part 3. 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. Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of patent rights. IsO shall not be held responsible for identifying any or all such patent rights. International Standard ISO 6601 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 2 Mechanicalproperties. This second edition cancels and replaces the first edition (isO 6601:1987), which has been technically revised. ISO 6601:2002(E) Introduction The resistance to movement of two surfaces against each other (sliding friction) consumes energy, causes wear and generates heat. In some applications, friction is a nuisance; others require a given level of friction (for example: brakes, shoe soles, etc.). It is important to be able to characterize the friction with certain parameters which are identified in this International Standard. Copvriaht International Oraanization for Standardizatior ISO 6601:2002(E) INTERNATIONALSTANDARD Plastics Friction and wear by sliding ldentification of test parameters 1 Scope conditions that test methods should address to determine these characteristics. It is intended to provide a basis for further International Standards dealing with methods of test and the specifications of materials. 2 General The sliding friction behaviour of one material against another can be defined by such terms as the coefficient of friction, rate of wear, resistance to seizure or the "pu-limit" factor1) These terms are dependent on various parameters which may be classified into three groups: a) intrinsic parameters relating to the materials involved, such as their nature, physico-chemical state, surface condition and finish; b) external parameters rela
