5、ent to the publication of this frestandard, the technical content shall not be changed to an extent that interchangeabilify is affected, physically or functionally, without re-identification of the standard. After examination and review by users and formal agreement of AECMA-STAN, it will be submitt
6、ed as a draft European Standard (prEN) to CEN (European Committee for Standardization) for formal vote and transformation to full European Standard (EN). The CEN national members have then to implement the EN at national level by giving the EN the status of a national standard and by withdrawing any

16、s The individual strands used for the conductors shall be cylindrical and shall be: - of nickel clad copper alloy for nominal cross sections of 0,4 mm2 (004) and 0,25 mm2(002) - of nickel clad copper for nominal cross sections 2 0,6 mm2 (006). The copper shall meet the requirements of IEC 28 and the
17、 copper alloy the requirements of EN 2234. 5.2 Construction 5.2.1 Number of cores See Table I.

18、mic resistance: 1 ,O3 5.2.2 Colour coding Outer insulation shall be white with a red stripe to indicate fire-resistant construction. This red stripe to be helical for cables with conductor sizes from 0,25 mm2 (002) to 5 mm2 (050) and helical or length wise for cables with conductors sizes from 9 mm2
19、 (090) to 68 mm2 (680). In order to allow a legible UV marking, the width of the stripe shall be between 0,3 mm and 0,5 mm. For multicore cable without jacket, each core shall be marked with its own designation. The colour of stripes is given in Table 2: Table 2 Number of cores Red Red Red Red Red R

21、rking The identification and marking of cables by the manufacturer shall be in accordance with EN 2234. As the designation required for orders is generally too long for use in electrical drawings, a shorter cross designation (without colour information) is given by the AECMA TR 6058 plus the corresp
22、onding AWG. This shorter designation shall be used for identification and marking as the following example: EXEMPLE Designation EN2346-003A006 Cross reference DL 20 EN DL 20 Reference to EN standard cable 3 mandatory spaces FRF! Manufacturer country code Type code I 9 Manufacturer code Year of manuf
23、acturing For multicore cable with jacket, the marking shall be optional on cores(s) and mandatory on jacket. For multicore cable without jacket, each core shall be marked with its own designation. The cables shall be capable of being printed with the use-applied markings according to EN 3838. 7 Technical specification See EN 2234.
