添付： ISO standards information for the draft of TPA.doc; Type approval standard of bilge pump in Japan.doc
件名： Japanese standard for TC8/SC1/WG1
Dear, Mr. Kurt Heinz
Thank you for sending the report and final list of delegate.
As instructed and invited by WG1, I send some information about our standard of bilge pump and possible change to ISO standards in attached files.
Also, I have some comments to the drafts as follows.
I hope this information will be some help for WG1.
Comment to the draft of TPA
Donning test in full load liferaft is questioned. We are conducting donning test in no load liferaft without inflating floor on the water. Full load liferaft seems to be more stable than with no load. So, if you suppose worse condition, liferaft in no load and no inflation of floor will be appropriate.
Comment to the survival equipment
For standard of compass, ISO 613 surely require illuminate the card, but the method of illumination seems to be supposed only by electric light so some change of expression will be needed to be in line with LSA code.

Type approval standard of bilge pump in Japan
||Salt spray test
The specimen shall be exposed to 5% salt solution spray for 8 hours in accordance with JIS Z 2371 (ISO
9227:1990) and then left for 16 hours without spray. This procedure shall be repeated three times until
72 hours in total.
|Salt spray test
The specimen shall show no corrosion which could affect its efficient functioning.
The specimen shall be operated at a height of 1.2m above to the water without priming any water. And a
time between the start of the operation and first discharge of water shall be measured.
The time between the start of the operation and first discharge of water shall be not more than 1 minute.
The specimen shall be operated at a height of 1.2m above to the water according to the manufacture's instruction,
and discharge rate shall be measured.
The discharge rate shall be not less than 23 liters per minute for a lifeboat of less than 7.3m in length
and not less than 32 liters per minute for a lifeboat of over 7.3m in length.
Water pressure of 1 kgf/cm2 shall be applied to the specimen for a period of 30 seconds.
The specimen shall not show any leakage.
The specimen shall be operated 10000 cycles continuously in normal operating condition and after the test,
capacity measurement shall be carried out.
Same as capacity measurement and the specimen shall show no damage which could affect its efficient functioning.
