§ 62.25-30 — -30 Environmental Design Standards

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

(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) Ambient air temperatures described in Table 1 of part 4-9-9/3 of the ABS Marine Vessel Rules.

(3) Electrical voltage and frequency tolerances described in Table 1 of part 4-9-9 of the ABS Marine Vessel Rules.

(4) Relative humidity of 0 to 95% at 45 °C.

(5) Hydraulic and pneumatic pressure variations described in Table 1 of part 4-9-9 of the ABS Marine Vessel Rules.

(b) Low voltage electronics must be designed with due consideration for static discharge, electromagnetic interference, voltage transients, fungal growth, and contact corrosion.
