1. (a) All automation must be suitable for the marine environment and must be designed and constructed to operate indefinitely under the following conditions:

   1. (1) Ship motion and vibration described in Table 1 of section 4-9-9 of the ABS Marine Vessel Rules (incorporated by reference; see § 62.05-1); note that inclination requirements for fire and flooding safety systems are described in § 112.05-5(c) of this chapter.
   2. (2) Ambient air temperatures described in Table 1 of part 4-9-9/3 of the ABS Marine Vessel Rules.
   3. (3) Electrical voltage and frequency tolerances described in Table 1 of part 4-9-9 of the ABS Marine Vessel Rules.
   4. (4) Relative humidity of 0 to 95% at 45 °C.
   5. (5) Hydraulic and pneumatic pressure variations described in Table 1 of part 4-9-9 of the ABS Marine Vessel Rules.
2. (b) Low voltage electronics must be designed with due consideration for static discharge, electromagnetic interference, voltage transients, fungal growth, and contact corrosion.

Note 1 to paragraph (a): Considerations should include normal dynamic conditions that might exceed these values, such as switching, valve closure, power supply transfer, starting, and shutdown.
