Temperature range for testing: from 270 C to 380 C. Temperature range for the calculation of the melting point energy: from 290 C to 36
21、0 C. 5.2 Requirements To achieve an acceptable PTFE tape sintering: the melting point temperature shall be (327 4) C with a 15 J/g to 25 J/g energy; the recrystallization temperature shall be 310 C minimum; the second melting point shall not exceed an energy of 25 J/g. The manufacturer shall record
22、in the test report which DSC apparatus have been used. NOTE The values recorded in the qualification test report shall be taken for reference of the manufacturing process. If it is necessary to carry out test on production cable, test shall be made with the same DSC apparatus and the values shall be
23、 compared to the reference values. 1) Published by: American Society for Testing and Materials (ASTM), 100 Barr Harbor Drive, PO Box C700, West Conshohocken, PA, 19428-2959 USA. blankBS EN 3475-414:2005 BSI 389 Chiswick High Road London W4 4AL BSI British Standards Institution BSI is the independent
