19、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 technical committees. Each member body interested in a subject for which a t

20、echnical 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 with the International Electrotechnical Commission (IEC) on all matters

21、 of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulate

22、d 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 document may be the subject of patent rights. ISO shall not be held responsible

23、for identifying any or all such patent rights. ISO 1628-1 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 5, Physical-chemical properties. This third edition cancels and replaces the second edition (ISO 1628-1:1998), of which it constitutes a minor revision intended primaril

24、y to correct an error in Subclause 9.1, paragraph 4 (starting: “The intrinsic viscosity shall be calculated from”), where, in line 2, “intrinsic-viscosity values” has been replaced by “inherent-viscosity” values.

36、solution. It defines the standard parameters that are applied to viscosity measurement, and can be used to develop standards for measuring the viscosities in solution of individual types of polymer. It can also be used to measure and report the viscosities of polymers in solution for which no separa

In non-Newtonian behaviour, which is the usual case with high-polymer solutions, the ratio varies with the shear rate. Su
