25、c) BSI ISO 8986-1:1993(E) BSI 04-2000iii 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 b
26、ody 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 Electro
27、technical Commission (IEC) on all matters of electrotechnical standardization. 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
28、vote. International Standard ISO 8986-1 was prepared by Technical Committee ISO/TC 61, Plastics, Sub-Committee SC 9, Thermoplastic materials. ISO 8986 consists of the following parts, under the general title Plastics Polybutene (PB) moulding and extrusion materials: Part 1: Designation system and ba
29、sis for specifications; Part 2: Preparation of test specimens and determination of properties.

30、led Copy, (c) BSI ISO 8986-1:1993(E) BSI 04-20001 1 Scope 1.1 This part of ISO 8986 establishes a system of designation for polybutene thermoplastic material which may be used as the basis for specifications. 1.2 The types of polybutene plastics are differentiated from each other by a classification
31、 system based on appropriate levels of the designatory properties a) density b) melt flow rate and on information about basic polymer parameters, intended application and/or method of processing, important properties, additives, colorants, fillers and reinforcing materials. 1.3 This part of ISO 8986
32、 is applicable to all butylene homopolymers and to copolymers of butylene with a maximum content of other 1-olefinic monomers of less than 50 % (m/m) and with a content of non-olefinic monomers with functional groups up to a maximum of 1 % (m/m). It applies to materials ready for normal use in the f
33、orm of powder, granules or pellets and to materials unmodified or modified by colorants, additives, fillers, etc. 1.4 It is not 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 dat
34、a or data on processing conditions which may be required to specify a material for a particular application and/or method of processing. A part 2 to this International Standard covering the preparation of test specimens and determination of properties is being prepared for use if such data are requi
35、red. 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 clause 3, introductory paragraph). 2 Normative references The following standards contain provisions which, through refer
36、ence in this text, constitute provisions of this part of ISO 8986. At the time of publication, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on this part of ISO 8986 are encouraged to investigate the possibility of applying the most recent
37、editions of the standards indicated below. Members of IEC and ISO maintain registers of currently valid International Standards. ISO 1043-1:1987, Plastics Symbols Part 1: Basic polymers and their special characteristics. ISO 1133:1991, Plastics Determination of the melt mass-flow rate (MFR) and the
38、melt volume-flow rate (MVR) of thermoplastics. ISO 1183:1987, Plastics Methods for determining the density and relative density of non-cellular plastics. 3 Designation and specification system The designation and specification system for thermoplastics is based on the following standardized pattern:
39、 The designation consists of an optional description block, reading “Thermoplastics”, and an identity block comprising the International Standard number and an individual-item block. For unambiguous coding, the individual-item block is subdivided into 5 data blocks comprising the following informati
40、on: Designation Description block (optional) Identity block International Standard Number block Individual-item block Data block 1 Data block 2 Data block 3 Data block 4 Data block 5 Data block 1:Identification of the plastic by its symbol PB in accordance with ISO 1043-1 and information about the p
41、olymerization process or composition of the polymer (see 3.1). Data block 2:Position 1: Intended application or method of processing (see 3.2). Licensed Copy: sheffieldun sheffieldun, na, Mon Nov 20 02:22:52 GMT+00:00 2006, Uncontrolled Copy, (c) BSI ISO 8986-1:1993(E) 2 BSI 04-2000 The first charac
42、ter of the individual-item block shall be a hyphen. The 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 (,). 3.1 Data block 1 In this data block, after the hyphen, polybutene plastics a
43、re identified by the symbol “PB”, in accordance with ISO 1043-1, followed by a hyphen and a single code-letter, giving additional information on the polymer as specified in Table 1. 3.2 Data block 2 In this data block, information about intended application and/or method of processing is given in po
44、sition 1 and information about important properties, additives and colour in positions 2 to 8. The code-letters used are specified in Table 2. If information is presented in positions 2 to 8 and no specific information is given in position 1, the letter X shall be inserted in position 1. 3.3 Data bl
45、ock 3 In this data block, the range of the density is represented by a 2-figure code-number (see 3.3.1) and the melt flow rate by a 3-figure code-number (see 3.3.2). The code-numbers are separated from each other by hyphens. If a property value falls on or near a range limit, the manufacturer shall
46、state which range will designate the material. If subsequent individual test values lie on, or on either side of, the limit because of manufacturing tolerances, the designation is not affected. NOTE 1Not all the combinations of the values of the designatory properties have to be provided for current
47、ly available polymers. 3.3.1 Density The density shall be determined in accordance with ISO 1183, method D, on a piece of melt-indexer extrudate. The sample, uncoloured and unfilled, is extruded from a standard melt indexer at 190 C in accordance with the method described in ISO 1133, under suitable
48、 conditions in order to obtain a strand of suitable length free of voids with a smooth surface. After being cut off, the strand is allowed to fall on a cool metal plate. It is then kept at a temperature of 23 C 2 C and (50 5) % relative humidity for 10 days prior to performance of the test. The poss
49、ible values of density are divided into 7 ranges, each represented by a 2-figure code-number as specified in Table 3.
