18、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 body interested in a subject for which a technical

19、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 elect

20、rotechnical 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 technical committees are circulated to the

21、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 not be held responsible for ident

22、ifying any or all such patent rights. ISO 15015 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 11, Products. This second edition cancels and replaces the first edition (ISO 15015:2007), of which it constitutes a minor revision in which the temperature in Tables 2, 3 and A.2

24、irements and test methods 1 Scope This International Standard specifies the requirements and test methods for solid flat extruded sheets of impact-modified acrylonitrile-styrene copolymer materials: acrylonitrile-butadiene-styrene (ABS), acrylonitrile-(ethylene-propylene-diene)-styrene (AEPDS) (comm

25、only known as AES) and acrylonitrile-styrene-acrylate (ASA), without fillers or reinforcing materials. This International Standard also applies to ABS, AEPDS and ASA sheet in rolled form. It applies only to thicknesses from 0,25 mm to 20,0 mm. 2 Normative references The following referenced document

33、 Requirements 4.1 Appearance Sheets shall be substantially free from bubbles, voids, cracks, visible impurities and other defects which would make them unfit for the intended use. Surfaces shall be substantially smooth, if not embossed, and free from grooves, sink marks or damage. Colorants shall be

34、 homogeneously distributed throughout the material. Slight colour variations due to variations in the extrusion compound or processing conditions are admissible. The exact extent of variations in any of the above, as well as gloss level specifications, if required, shall be agreed between the intere

35、sted 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 variation from the nominal value, h1, in millimetres, shall satisfy the requirement h1 u (0,03 mm + 0,04 hn) (1) where hnis the nominal sheet

Within any individual sheet, the maximum thickness variation, h2, in millimetres, shall satisfy the requirement h2 u (0,03 mm + 0,02 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

37、 as agreed between the interested parties. Unless agreed differently, the length shall be in the direction of extrusion. For any individual sheet selected at random 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. T
