scope:

This NES outlines the principal types and causes of corrosion found in Naval Equipment and recommends procedures or processes to be applied in order to provide adequate protection.

Design features which assist in preventing the formation of corrosion are highlighted and suitable protective finishes for the majority of the metals commonly used by MOD(PE) are listed.

Processing Drawings

Process and procedure details which are to be adopted in order to provide corrosion protection are contained in drawings related to and supporting this NES.

These Process Drawings are available primarily as 35 millimetre microfilm aperture cards. Hard copy will be issued only when absolutely necessary.
