20、y: London South Bank University, London South Bank University, Wed Jan 02 02:18:44 GMT+00:00 2008, Uncontrolled Copy, (c) BSI iv Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing Interna
21、tional 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
22、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 task of technical
23、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. Attention is drawn to t
24、he 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 15015 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 11, Products, in collaboration with Techn
25、ical Committee CEN/TC 249, Plastics, of the European Committee for Standardization (CEN).

34、er ABS extrusion materials as defined in ISO 2580-1 or AEPDS (AES) or ASA extrusion materials as defined in ISO 6402-1, without fillers or reinforcing materials. The extrusion materials can contain additives such as processing aids, stabilizers, flame-protective agents and colorants. Compounds and a
35、dditives of unknown identity shall not be used. NOTE Legal conditions may necessitate a specific choice of extrusion material (see 4.3.3). 4 Requirements 4.1 Appearance Sheets shall be substantially free from bubbles, voids, cracks, visible impurities and other defects which would make them unfit fo
36、r the intended use. Surfaces shall be substantially smooth, if not embossed, and free from grooves, sink marks or damage. Colorants shall be homogeneously distributed throughout the material. Slight colour variations due to variations in the extrusion compound or processing conditions are admissible
37、. The exact extent of variations in any of the above, as well as gloss level specifications, if required, shall be agreed between the interested parties. Sheets shall be examined in accordance with 5.3. 4.2 Dimensional tolerances 4.2.1 Thickness Within any delivery of sheets, the maximum thickness v
38、ariation from the nominal value, h1, in millimetres, shall satisfy the requirement h1 u (0,03 mm + 0,04 hn) (1) where hn is the nominal sheet thickness, in millimetres. Within any individual sheet, the maximum thickness variation, h2, in millimetres, shall satisfy the requirement h2 u (0,03 mm + 0,0
39、2 hn) (2) Testing shall be in accordance with 5.4.1. 4.2.2 Length and width The nominal length, ln, and nominal width, bn, of sheets shall be as agreed between the interested parties. Unless agreed differently, the length shall be in the direction of extrusion. For any individual sheet selected at r
40、andom from any delivery, the tolerances on length and width shall be in accordance with Table 1. Testing shall be in accordance with 5.4.2.
