order
This translation is based on the original Japanese industrial
standards and revised by the Minister of economy, trade and
industry and the Minister of land, infrastructure, transport
and tourism. The Japanese Industrial Standards Committee
adopted its deliberations.Japan wire and cable manufacturers
association and Japan Standards Association proposed to
revise Japan's industrial standards. They attached
importance to the drafting of the draft, requiring that the
draft should be based on Article 12, Article 1 of the

industrial standardization law and be applicable to the
revised Article 14.
Therefore, JIS C 3410:1999 has been replaced by this standard,
and can be retired.
JIS is protected by copyright law.
It is worth noting that some parts of the standard may
conflict with patent rights when patent applications are
disclosed to the public, or when the rights of utility models
or utility models applying for registration are disclosed to
people with technical knowledge.The Minister concerned and
the Japanese Industrial Standards Committee will not be
responsible for the appraisal of the patent right after the
application for patent is made public, or when the right of
the utility model or the application for registration of the
utility model is made public to the people who have already
expressed their technical knowledge.

Cables and cords for marine electrical appliances
Introduction
This Japanese industrial standard is based on the third
edition of IEC 60092-351 published in 2004, the second
edition of IEC 60092-353 published in 1995 and the first
edition of its revision in 2001, the second edition of IEC
60092-354 published in 2003, the first edition of IEC 60092-
359 published in 1987, the first edition of its revision in
1994, the second edition of its revision in 1999 and the
second edition of IEC 60092-376 published in 2003.The
technical content of the standards mentioned above has been
modified according to the Japanese industrial standards.This
is to prepare a standard that can reflect the real situation
of ship cables and flexible wires in this country.The
explanation of the modification is listed in Appendix JD.

The continuous sideline or dotted part, and the contents
of annex JA, annex JB and annex JC are not given in the
corresponding international standards.
1 Scope
This standard covers cables, flexible wires and
insulating wires for power equipment on board ships.
Note: this standard is consistent with the international mark
as follows:
IEC 60092-351:2004 marine electrical equipment - Part 351:

c) After three cycles, the sample shall be subjected to partial discharge test
as required. http://www.tiankangcable.com/marine-cable.html
7.15 Power frequency voltage test after withstand voltage
impact
The test requirements of power frequency voltage after
withstand voltage impact are as follows.
b) This test shall be carried out above the maximum rated working
temperature of the insulation, i.e. conductortemperature of 5 ° C.

c) The corresponding http://www.tksiliconerubbercable.com value of the
cable withstanding 10 positive and 10 negative voltage shocks is shown in
table 13.
Table 13 withstand voltage impact
Setting: kV
Rated voltage of wire U0
3.6 6.0
Test voltage (peak) 60 75
d) After the test of B) and C), the cable sample shall be subject to power
frequency voltage test at room temperature for 15min (on any one wire
core).
