The work of preparing International Standards is normally carried out through ISO technical 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 with 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, Part3. 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 part of ISO1628 may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. International Standard ISO1628-3 was prepared by Technical Committee ISO/TC61, Plastics, Subcommittee SC9, Thermoplastic materials. This third edition cancels and replaces the second edition (ISO1628-3:2001), of which it constitutes a minor revision (the third confirms Ubbelohde viscometers type in 5.1, and in 7.4.2 the solution method is modified ). ISO1628 consists of the following parts, under the general title Plastics Determination of the viscosity of polymers in dilute solution using capillary viscometers: Par1: General principles Part2: Poly(vinyl chloride) resins Part3: Polyethylenes and polypropylenes Part4: Polycarbonate (PC) moulding and extrusion materials Part5: Thermoplastic polyester (TP) homopolymers and copolymers Part6: Methyl methacrylate polymers Licensed CopyChinese University of Hong Kong, 21/10/2008 04:22, Uncontrolled Copy, (c) BSI Licensed CopyChinese University of Hong Kong, 21/10/2008 04:22, Uncontrolled Copy, (c) BSI 1 Scope This part of ISO1628 defines particular conditions for determining the reduced viscosity (also known as viscosity number) and intrinsic viscosity of polyethylenes and polypropylenes at 135°C in dilute solution.
