These test methods are intended to be referenced in standards for cable construction and for cable materials. NOTE 1 Non-met
25、allic materials are typically used for insulating, sheathing, bedding, filling or taping within cables. NOTE 2 These test methods are accepted as basic and fundamental and have been developed and used over many years principally for the materials in all energy cables. They have also been widely acce
26、pted and used for other cables, in particular optical fibre cables, communication and control cables and cables for ships and offshore applications.

Unless otherwise specified, tests shall be carried out at room temperature. 4.2 Pre-c
31、onditioning All the tests shall be carried out not less than 16 h after the extrusion or cross-linking, if any, of the sheathing compounds. 4.3 Sample and test piece preparation Five test pieces shall be prepared in accordance with the procedures described in IEC 60811-501. 4.4 Determination of the
32、cross-sectional area of the test piece See the test method in IEC 60811-501. BS EN 60811-404:201260811-404 IEC:2012 7 4.5 Oil to be used Unless otherwise agreed, the mineral oil to be used shall be oil no. 2 (IRM 902) as described in ISO 1817. 4.6 Procedure The test pieces shall be immersed in the o
33、il bath, previously heated to the specified test temperature, and shall be maintained in the oil at that temperature for the specified time (see standard for the type of cable). At the end of the specific duration, the test pieces shall be removed from the oil, blotted lightly to remove excess oil a
34、nd suspended in air at ambient temperature for at least 16 h but not more than 24 h, unless otherwise specified in the relevant cable standard. At the end of this period, any further excess oil shall be removed by lightly blotting the test pieces. 4.7 Determination of mechanical properties See the t
35、est method in IEC 60811-501. 4.8 Expression of results The calculation of tensile strength shall be based on the cross-sectional area of the test piece measured before immersion (see 4.2.2). The difference between the median value obtained on the five test pieces immersed in oil and the median value
36、 of the values obtained for the untreated test pieces (see IEC 60811-501), expressed as a percentage of the latter, shall not exceed the percentage specified in the standard for the type of cable. If required by the standard for the material in the relevant standard for the type of cable, the values
37、 found for the aged test pieces shall be calculated, in terms of variation compared to the untreated test pieces according to the following formulae: 100UUET=TTTV (1) 100UUEE=EEEV (2) where VTis the variation of the tensile strength in per cent; TEis the tensile strength of aged test piece; TUis the
38、 tensile strength of untreated test piece; VEis the variation of the elongation at break in per cent; EEis the elongation at break of aged test piece in per cent; EUis the elongation at break of untreated test piece in per cent. NOTE The untreated specimen is kept at room temperature. 5 Test report
