22、on 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 committee has been established has the right to be represented on that committee
23、. 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 electrotechnical standardization. International Standards are drafted in accordance w
24、ith 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 member bodies for voting. Publication as an International Standard requires appr
25、oval 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 identifying any or all such patent rights. ISO 13000-1 was prepared by Technical Comm

28、s for processed unfilled polytetrafluoroethylene (PTFE) products, which may occur in several forms. The PTFE used to make the semi-finished product is described in ISO 12086-1 and, as provided in ISO 12086-1, may contain up to 1 % of a comonomer. The PTFE used to make the semi-finished product may b
29、e virgin, reprocessed or recycled resin. The addition of up to 1,5 % by mass of pigment or colorant is permitted. This part of ISO 13000 allows for four grades based on tensile strength and elongation at break. The semi-finished products can be as-processed (type P) or dimensionally stabilized (type
30、 S) and may also have specified electrical properties or other properties when they are required for an application. NOTE References to other standard specifications for semi-finished products made from polytetrafluoroethylene are listed in Annex A for information. 2 Normative references The followi
31、ng referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies.

EN ISO 13000-1:20052 3.1.1 moulded basic shape
34、 PTFE semi-finished product made by preforming and sintering without additional processing 3.1.2 semi-finished product material, in the form of skived tape, sheets, rods, tubes, tubing, moulded basic shapes or special shapes, that is produced for use either directly without further fabrication or in
35、 fabricating end use products, or both 3.1.3 skived tape film or sheet prepared by cutting, slicing or shaving NOTE The term “veneered tape” is deprecated. 3.2 Abbreviated terms and symbols The abbreviated terms given in ISO 1043-1 are applicable to this part of ISO 13000. 4 Requirements for PTFE se
36、mi-finished products 4.1 General After considering the specific shape, dimensions and dimensional tolerances, the primary basis for specifying a semi-finished product of PTFE is the tensile strength and percentage elongation at break of the product. Tests to determine the values for specification sh
37、all be run in accordance with the methods in ISO 13000-2. The semi-finished product is identified as “type P” for as-processed or “type S” for stabilized and also may be designated as “type E” with specified electrical properties when required for a particular application. The exclusion of the use o
38、f reprocessed or recycled material shall be specified if needed in order to meet special customer requirements. The values required for other properties are given in their respective subclauses. 4.2 Dimensions and dimensional tolerances 4.2.1 General Dimensional tolerances shall be measured at 23 C

40、n powder The standard tolerance on inner diameter and wall thickness is: Code-letter Dimension Tolerance a Inner diameter 500 mm 20+% The tube shall be capable of being machined concentrically to the required nominal dimensions and the eccentricity of the bore shall not exceed 4,0 % of the nominal i
41、nside diameter. NOTE The machining of the tube to the nominal dimensions with the inner and outer surfaces concentric is feasible if the maximum inner diameter, calculated by difference between the outer diameter and two times the minimum wall thickness, is within the specified tolerance. For a moul
42、ded tube, the tolerance on the outer diameter shall be a minimum value. A larger diameter than is provided for by the plus tolerance is acceptable for moulded tube, either type P or S, that is to be machined to the final dimension. 4.3 Tensile strength and percentage elongation at break The grade fo
43、r semi-finished products is determined by the minimum values of tensile strength and percentage elongation at break shown in Table 1, determined as specified in ISO 13000-2. NOTE There are some configurations of PTFE that might not be able to be produced with a high grade classification. Table 1 Gra

The maximum change in any dimension shall not exceed 0,5 %, determined as specified in ISO 13000-2. EN ISO 13000-1:200554.5 Densit
45、y All semi-finished products shall have a density in the range of 2,13 g/cm3to 2,19 g/cm3except that: a) products made from reprocessed material or blends with reprocessed material shall have a density in the range of 2,14 g/cm3to 2,23 g/cm3; b) tubing extruded from coagulated dispersion powders sha
46、ll have a density in the range of 2,13 g/cm3to 2,23 g/cm3. 4.6 Hardness All products that have a shape or dimensions such that measurements can be made precisely shall have a ball indentation hardness of more than 23 MPa or the hardness determined using the Shore D test shall have a value greater th
47、an 54. Both of the hardness tests are described in ISO 13000-2. 4.7 Colour PTFE that does not contain a colorant shall be white to transparent after sintering. Visual perception of whiteness is usually adequate to appraise this characteristic of semi-finished products. If a quantitative value is req
48、uired for whiteness, the test procedure in ISO 13000-2 shall be used. The value required shall be as agreed upon between producer and purchaser. If pigment or colorant has been added, its presence shall be reported in all documentation related to a particular product. NOTE The presence of pigments o
49、r colorants may affect some properties of the material, e.g. chemical resistance and electrical properties, and it is advisable for the purchaser and supplier to agree upon the type and grade of pigment to be used. 4.8 Dielectric strength (DS), breakdown voltage and electrical flaws 4.8.1 General This requirement applies only to materials coded E with specified electrical properties required for an application. The required values for the various shapes reflect the same dielectric strength when corrected for thickness by the sta
