21、1183-1:2012ISO 1183-1:2012(E)ForewordISO (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 intereste

22、d 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 Com

23、mission (IEC) on all matters 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 technica

24、l 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 document may be the subject of patent rights. ISO shall

25、 not be held responsible for identifying any or all such patent rights.ISO 1183-1 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 5, Physical-chemical properties.This second edition cancels and replaces the first edition (ISO 1183-1:2004), which has been technically revised.

26、The main changes compared to the previous edition are as follows:a) the equation used to calculate the dependence of the density of air on pressure and temperature in Clause 6 has been replaced by two equations, one for non-tropical conditions, the other for tropical conditions;b) a new annex (Annex

27、 B) has been added showing how the basic air buoyancy correction equation Equation (5) is derived.ISO 1183 consists of the following parts, under the general title Plastics Methods for determining the density of non-cellular plastics: Part 1: Immersion method, liquid pyknometer method and titration

29、ERNATIONAL STANDARD ISO 1183-1:2012(E)Plastics Methods for determining the density of non-cellular plastics Part 1: Immersion method, liquid pyknometer method and titration methodWARNING The use of this part of ISO 1183 might involve hazardous materials, operations or equipment. This part of ISO 118

30、3 does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this part of ISO 1183 to establish appropriate health and safety practices and to determine the applicability of any regulatory limitations prior to use.1 ScopeThis part

31、 of ISO 1183 specifies three methods for the determination of the density of non-cellular plastics in the form of void-free moulded or extruded objects, as well as powders, flakes and granules. Method A: Immersion method, for solid plastics (except for powders) in void-free form. Method B: Liquid py

32、knometer method, for particles, powders, flakes, granules or small pieces of finished parts. Method C: Titration method, for plastics in any void-free form.NOTE This part of ISO 1183 is applicable to pellets as long as they are void-free. Density is frequently used to follow variations in physical s

33、tructure or composition of plastic materials. Density might also be useful in assessing the uniformity of samples or specimens. Often, the density of plastic materials will depend upon the choice of specimen preparation method. When this is the case, precise details of the specimen preparation metho

34、d will have to be included in the appropriate material specification. This note is applicable to all three methods.2 Normative referencesThe following referenced documents are indispensable for the application of this document.

39、here shall be in accordance with ISO 291. In general, conditioning specimens to constant temperature is not required, because the determination itself brings the specimen to the constant temperature of the test.Specimens which change in density during the test to such an extent that the change is gr

When changes in density with time or atmospheric conditions are the primary purpose of the measurements, the specimens shall be conditioned as described in the materia
