12、es (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 committee has been established has the right to be represented on that committee. International organizations
13、, 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 electrotechnical standardization. International Standards are drafted in accordance with the rules given in the IS
14、O/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 member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the
15、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 identifying any or all such patent rights. ISO 15015 was prepared by Technical Committee ISO/TC 61, Plastics, Subc

The extrusion materials can contain additives such as processi
27、ng aids, stabilizers, flame-protective agents and colorants. Compounds and additives 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,
28、 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 homogeneously distributed throughout the material. Slight colour variations due to
29、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 interested parties. Sheets shall be examined in accordance with 5.3. 4.2 Dimensional toler
30、ances 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 hn is the nominal sheet thickness, in millimetres. Within any individual sheet, the maximum thickness vari
31、ation, 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 as agreed between the interested parties. Unless agreed differently, the length sh
32、all 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. Table 1 Tolerances on length and width of sheets Values in millimetres Tolerances No

46、and transversely from locations evenly distributed over the length and width of the sheet. With sheets in rolled form, a 2 m sample shall be cut from the end of the roll to prepare test specimens. The surfaces of the test specimens shall be free from damage and faults in order to avoid notch effects
47、. Should any burrs be formed on the test specimens during preparation, these shall be eliminated without damaging the surfaces of the specimens. If required, the cut edges shall be finished with abrasive paper (grain size 220 or finer), the direction of abrasion being along the length of the test sp
48、ecimens. If it is necessary to machine the sheet to reduce it to the thickness required, one original surface shall be left intact. In particular, test specimens over 4,2 mm thick intended to be used in the tests described in 5.6.1 to 5.6.6 shall be machined down on one side to a thickness of 4,0 mm 0,2 mm in accordance with ISO 2818.
