IEC 60092-359:1999 pdf download.Electrical installations in ships – Part 359: Sheathing materials for shipboard power and telecommunication cables
1 Scope and object
This standard specifies the test requirements for mechanical and particular characteristics of
sheathing materials intended to be used in shipboard power and telecommunication cables.
2 Sheathing materials
2.1 General
The types of sheating compounds covered by this standard are listed in table I together with
abbreviated designation and operating temperature limits of the conductor of the cables for
which they can be used.
2.2 Mechanical characteristics
The test requirements for mechanical characteristics of both aged and non-aged sheathing
compounds are listed in table II.
If the apparatus has been pre-cooled, a shorter cooling period is permissible, but not less than 4 h provided that the samples have attained the prescribed test temperature. If the apparatus and test specimens have been pre-cooled, a cooling time of 1 h after each test piece has been fixed to the apparatus is sufficient. If the apparatus has been pre-cooled, this period may be reduced to 2 h, and if the apparatus and test piece have been pre-cooled, the conditioning time after the test piece has been fixed in the apparatus shall be not less than 30 min. If the apparatus has been pre-cooled, a shorter cooling period is permissible, but not less than 1 h provided that the test pieces have attained the prescribed test temperature. It shall be consistent with the maximum optical smoke density to be obtained by cable testing.
