20-42  Fluorescent Penetrant Inspection

This specification provides for surface inspection of parts fabricated from nonmagnetic 

materials to detect discontinuities open to the surface, such as cracks, cold shuts, laps, 

porosity and other surface defects.

Applicable requirements and limitations of ASTM E 1417 shall apply.  After inspection is 

complete, solvent clean parts.

The step-by-step procedure and equipment used to perform the inspection shall be 

accomplished per ASTM E 1417.

A.  Inspection Criteria

Parts inspected by fluorescent penetrant method shall be accepted or rejected 

on basis of acceptance limits specified.  If acceptance limits are not specified, 

rejectable surface defects and any of the following:

 

y

Cracks

 

y

Seams

 

y

Cold shuts or laps

 

y

Surface inclusions

 

y

In castings, aligned discontinuous surface indications other than cracks, cold 

shuts and inclusions are rejectable if more than 3/8 inch in length.

20-50  Corrosion Control

[Reserved].

20-60  Priming and Painting

This specification outlines preparation and application requirements for primers and topcoat.  

Primers provide corrosion protection and a final finish or a base for topcoat.  Use only 

approved materials listed in 

§

 20-70.

Do not prime or paint with a topcoat finish the following areas (unless directed):

 

y

Sliding friction joints.

 

y

Stainless steel parts.

 

y

Swivel joints and adjustable rod ends.

 

y

Plastic, rubber, electrical components and wires or similar materials.

 

y

Bolted joints where torque is a specific requirement for clamping action.

 

y

Bearing press fit or close tolerance slip fit joints (except where wet chromate primer is 

part of the assembly procedure).
