Section 5 Loading Instruments

501. Application

1. The requirements of this Section apply to tests and inspection for type approval of loading instru-

ments fitted on board for the calculation

Ch 1, 307. and 405. of the Rules, and

of stability in accordance with the requirements of Pt 1,

for the calculation of longitudinal strength in accordance

with the requirements of Pt 3, Ch 3, 104. of the Rules and for type approval of container lashing

calculation instrument in accordance with the requirements of Pt 7, Annex 7-2, 9. of the Guidance.

2. Related to Par 1 above, the design approval of the Society for the software (program) used in the loading instruments or container lashing calculation instruments refer to requirements specified in Ch 4, Sec 2. of this Guidance.

3. The requirements of this Section apply to the instruments used on land to assist several ships.

502. Data to be submitted

The environmental test procedures are in 102.

to be submitted to the Society in addition to those specified

503. Requirements

1. Construction

The loading instrument (computer) is under the following conditions, except

to have sufficient endurance and no difficulty for operating where fitted in a special place. Also, humidity is to be con-

sidered especially, and a self-monitoring function is recommended to be computerized to prevent fallacy or error caused by failure in the circuit, etc.

(1) Ambient temperature : 0°C to 45°C

(2) Vibration:

Amplitude ±1.0 mm at 2

Hz to 13.2 Hz

Acceleration ±0.7 at 13.2 Hz to 100 Hz

The vibration during operation is to range from 2 Hz to 100 Hz with an acceleration of ± 0.05

.

(3) Inclination:

Longitudinal inclination 10°

Transverse inclination 22.5°

(4) Power supply variation:

(A) A.C. power supply

(B) D.C. power supply

+30 % to -25 % for rated voltage for equipment connected to the battery during charging

+20 % to -25 % for rated voltage for equipment not connected to the battery during charg- ing

2. The loading instrument is to have proper input/output function including printer. When the printer is provided separately, the type test for the printer is not required.

504. Test and inspection

1. Environmental test

Environmental tests of loading instruments are followed by test item 1 through 9 of Table 3.23.1 of

2304. However, the tests for loading instruments to be used on land are not required as a rule.
