2.3.1 General

Materials shall be suitable for the conditions of use, and, in particular, arty material in contact with ammonia shall be

compatible with ammonia.

NOTE Appcndi C gives guidance on the control of risks of stress corrosion cracking of carbon steel in the presence of ammonia.

2.3.2 Minimum design temperature

Materials shall he selected and equipment shall bc designed for a minimum temperature appropriate for the duty and in accordance

with the applicable design Standard. The atmospheric boiling point of ammonia is —33.3?C and this temperature would usually

represent the minimum operating temperature for tanks and other equipment containing liquid anhdrous ammonia capable of being

depressuriicd to atmospheric conditions. Lower equilibrium temperatures are possible at ammonia partial pressures less than

atmospheric. (See Appendix A.)

2.4 ILECTRICAL EQIIPMFNT AND WIRING.

Flcctrical equipment and wiring for use in anhydrotis ammonia installations shall be installed and maintained in accordance with

AS/NZS 3000.
