(Revision of ISO 2859-1:1989)EN ISO 11833-2:2006 (E)33 MaterialSheets shall be fabricated from unplasticized PVC compounds as defined in ISO 1163-1:1995, subclause 1.3.Compounds may contai
27、n additives such as stabilizers, lubricants, processing aids, impact modifiers, flameretardants and colourants. Compounds and additives of unknown identity and composition shall not be used for theprocessing of sheets.NOTE Legal considerations may cause a specific choice of compound.4 Classification
28、Sheets are classified into four groups (three of which are subdivided into two classes) by the numerical values ofthe two most important properties, i.e. the tensile impact strength and the Vicat softening temperature (see table 3).5 Requirements5.1 AppearanceThe surface shall be free of noticeable
29、flaws, cracks, mottling, voids, bubbles, impurities and other defects whichare not acceptable for the application envisaged. The sheet shall have a smooth surface, except for embossedsheets which shall have a uniform pattern. Any further requirements concerning appearance shall be agreedbetween the
30、interested parties.5.2 ColourColourants shall be distributed uniformly throughout the material. Admissible differences in colour within a sheet andamongst sheets shall be agreed between the interested parties as required.5.3 Dimensions5.3.1 Length, width and rectangularityThe length and width of she

36、.1 General6.1.1 SamplingTake a sample sufficient to determine the compliance of the material with this specification. The sampling proceduregiven in ISO 2859-1 is recommended.6.1.2 Preparation of specimensPrepare all specimens in accordance with ISO 2818. Prepare the specimens for tensile strength,
37、tensile impactstrength and dimensional change on heating by stamping or cutting. The surface of the specimens shall be free ofany damage or faults in order to avoid notch effects. Should any burrs be present on a specimen, remove themwithout damaging the surface.6.1.3 Conditioning and testing of spe
38、cimensUnless otherwise specified in the applicable test method, carry out testing in one of the standard atmospheresspecified in ISO 291, after conditioning the specimens for at least 16 h in the same atmosphere.6.2 Appearance examinationExamine the surfaces and cut edges with the naked eye from a d
39、istance of 60 cm for noticeable flaws, cracks,mottling, voids, bubbles, impurities and other defects, inspecting the sheet in the direction opposite to that of theincident light.6.3 Dimensions6.3.1 Measure the length, width and diagonals of the sheet to the nearest 1 mm, using a calibrated ruler.6.3
