The work of p
16、reparing 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,
17、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, Part 2. The main ta
18、sk of technical committees is to prepare International Standards. 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. Attenti
19、on 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 for identifying any or all such patent rights. ISO 8986-1 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 9, Thermoplastic materia
20、ls. This second edition cancels and replaces the first edition (ISO 8986-1:1993), which has been technically revised. The main changes are as follows: it has been made clear that the standard concerns polybutene-1 as opposed to its isomer polyisobutene; density has been deleted as a designatory prop
21、erty; the only other designatory property, melt mass-flow rate (MFR), has been replaced by melt volume-flow rate (MVR); 190 C/5,0 kg has been added to the sets of conditions which can be used for the measurement of MVR.

23、lybutene-1 (PB-1) moulding and extrusion materials Part 1: Designation system and basis for specifications 1 Scope 1.1 This part of ISO 8986 establishes a system of designation for polybutene-1 (PB-1) thermoplastic materials which may be used as the basis for specifications. For the sake of simplici
24、ty, the designation polybutene and the abbreviation PB are used in both parts of ISO 8986. 1.2 The types of polybutene plastics are differentiated from each other by a classification system based on appropriate levels of the designatory property melt volume-flow rate and on information about basic p
25、olymer parameters, intended application and/or method of processing, important properties, additives, colorants, fillers and reinforcing materials. 1.3 This part of ISO 8986 is applicable to all butene homopolymers and to copolymers of butene with a maximum content of other 1-olefinic monomers of le
26、ss than 50 % by mass and with a content of non-olefinic monomers with functional groups up to a maximum of 1 % by mass. It applies to materials ready for normal use in the form of powder, granules or pellets and to materials unmodified or modified by colorants, additives, fillers, etc. 1.4 It is not
27、 intended to imply that materials having the same designation give necessarily the same performance. This part of ISO 8986 does not provide engineering data, performance data or data on processing conditions which may be required to specify a material for a particular application and/or method of pr
28、ocessing. 1.5 In order to specify a thermoplastic material for a particular application or to ensure reproducible processing, additional requirements may be given in data block 5 (see 3.1). 2 Normative references The following referenced documents are indispensable for the application of this docume
29、nt. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

31、based on the following standardized pattern: Designation Identity block Individual-item block Description block (optional) International Standard number block Data block1 Data block2 Data block3 Data block 4 Data block5 The designation consists of an optional description block, reading “Thermoplasti
32、cs”, and an identity block comprising the International Standard number and an individual-item block. For unambiguous coding, the individual-item block is subdivided into five data blocks comprising the following information: Data block 1: Identification of the plastic by its symbol PB in accordance
33、 with ISO 1043-1 and information about the polymerization process or composition of the polymer (see 3.2). Data block 2: Position 1: Intended application or method of processing (see 3.3). Positions 2 to 8: Important properties, additives and supplementary information (see 3.3). Data block 3: Design
34、atory properties (see 3.4). Data block 4: Fillers or reinforcing materials and their nominal content (see 3.5). Data block 5: For the purpose of specifications, a fifth data block may be added containing additional information. The first character of the individual-item block shall be a hyphen. The
35、data blocks shall be separated from each other by commas. If a data block is not used, this shall be indicated by doubling the separation sign, i.e. by two commas (,). 3.2 Data block 1 In this data block, after the hyphen, polybutene plastics are identified by the symbol PB, in accordance with ISO 1
36、043-1, followed by a hyphen and a single code-letter giving additional information on the polymer as specified in Table 1.

NOTE 1 In
43、 this edition of ISO 8986-1, melt mass-flow rate (MFR) has been replaced by melt volume-flow rate (MVR). If the MVR value falls on or near a range limit, the manufacturer shall state which range will designate the material. If subsequent individual test values lie on, or on either side of, the limit
44、 because of manufacturing tolerances, the designation is not affected. NOTE 2 Not all values of MVR are necessarily provided by currently available polymers.
