15、defined in ISO 12086-1, without fillers or reinforcing materials. The extrusion materials can contain additives such as processing aids, stabilizers and colorants. Materials and additives of unknown identity shall not be used. NOTE Legal conditions may necessitate a specific choice of extrusion mate

DIN ISO 15014:2015-1254 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 and free from sharp grooves, sink marks

17、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. The exact extent of variations in any of the above shall be agreed between the interested parties. Sheets sha

18、ll be examined in accordance with 5.3. 4.2 Dimensional tolerances 4.2.1 Thickness For any individual sheet, the thickness tolerance with reference to the nominal thickness shall be as given by h u (0,08 mm + 0,03 hn) (1) where h is the tolerance on the thickness, in millimetres; hnis the nominal thi

19、ckness, in millimetres. 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

20、 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.

22、hall be cut both longitudinally 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 extrusion direction shall be marked on the test specimens. The surf

23、aces of the test specimens shall be free from damage and faults in order to avoid notch effects. Should any burrs occur 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

24、 (grain size 220 or finer), the direction of abrasion being along the length of the test specimens. 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 te

25、sts described in 5.5 to 5.7 shall be machined down on one side to a thickness of 4,0 mm 0,2 mm in accordance with ISO 2818. 5.1.2 Conditioning Any production quality control test specimens shall be conditioned for at least 16 h in accordance with ISO 291 or as specified in the appropriate material s

26、tandard. Shorter conditioning times may be used by agreement between the interested parties when it can be shown that there is no significant difference in the results obtained. 5.1.3 Testing Testing shall be carried out under conditions which are in accordance with ISO 291 or as specified in the ap

27、propriate material standard unless otherwise agreed between the interested parties or specified in the individual test standards. 5.2 Delivery condition Sheets shall be visually examined when delivered to ensure freedom from mechanical damage or other obvious defects. Sheets can be inspected by ultr

28、asonic or X-ray methods where required. DIN ISO 15014:2015-1285.3 Appearance Where possible, sheets shall be examined for visual defects by transmitted light using a suitable light source. Otherwise, sufficiently bright reflected light shall be used. Any defects thus identified shall be compared wit
