6、 permitted without license from IHS -,-,- ISOISO 6721-10:1999(E) iii Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technic
7、al 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-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely wi
8、th 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 3. Draft International Standards adopted by the technical committees are circulated to the
9、 member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. International Standard ISO 6721-10 was prepared by Technical Committee ISO/TC 61,Plastics, Subcommittee SC 2,Mechanical properties. This second edition cancels
10、and replaces the first edition (ISO 6721-10:1997), which has been technically revised. ISO 6721 consists of the following parts, under the general titlePlastics Determination of dynamic mechanical properties: ?Part 1: General principles ?Part 2: Torsion-pendulum method ?Part 3: Flexural vibration Re
11、sonance-curve method ?Part 4: Tensile vibration Non-resonance method ?Part 5: Flexural vibration Non-resonance method ?Part 6: Shear vibration Non-resonance method ?Part 7: Torsional vibration Non-resonance method ?Part 8: Longitudinal and shear vibration Wave-propagation method ?Part 9: Tensile vib

15、s the general principles of a method for determining the dynamic rheological properties of polymer melts at angular frequencies typically in the range 0,01 rad.s?1to 100 rad.s?1by means of an oscillatory rheometer with a parallel-plate geometry. Angular frequencies outside this range can also be use
16、d (see note 1). The method is used to determine values of the following dynamic rheological properties: complex shear viscosity ?*, dynamic shear viscosity ?, the out-of-phase component of the complex shear viscosity ?, complex shear modulus G*, shear loss modulus G and shear storage modulus G. It i
17、s suitable for measuring complex shear viscosity values typically up to approximately 10 MPa.s (see note 2). NOTE 1The angular-frequency measurement range is limited by the specification of the measuring instrument and also by the response of the specimen. When testing using angular frequencies lowe
18、r than 0,1 rad.s1the test time can increase significantly as the time taken to obtain a single measurement is proportional to the reciprocal of the angular frequency. Consequently, when testing at low angular frequencies degradation or polymerization of the specimen is more likely to occur and have
19、an effect on the results. At high angular frequencies the specimen may distort or fracture at the edge, consequently invalidating the test results. NOTE 2The range of complex shear viscosity values that can be measured is dependent on the specimen dimensions and also the specification of the measuri
20、ng instrument. For a specimen of given dimensions, the upper limit of the range is limited by the machines torque capacity, angular-displacement resolution and compliance. However, correction can be made for compliance effects. 2 Normative references The following normative documents contain provisi
