The Pits of Penetration
Penetrant oils can cause explosion if they come into contact with liquid oxygen, Developer materials can absorb and retain moisture resulting in corrosion and Penetrant residue in flaws seriously affect weld quality if not removed prior to welding, are all good reasons to do this very important step
What is post cleaning
This method needs engineering authorization before being used
What is Method A water washable
This method is highly sensitive and can detect small tight discontinuities
What is Method C: Solvent removable
These can cause explosion if they come into contact with liquid oxygen
What is Penetrant oils
Developer materials can absorb and retain moisture resulting this detrimental condition if not properly removed after a penetrant inspection
What is Corrosion
Temperature can reach up to 750°F using this equipment, so.. Do not operate with cracked, chipped, ill-fitting filters and Do not operate if flammable vapors are present.
What is UV-A lamps
precautions should be taken because this is harmful to the Eyes and skin
What is Ultraviolet radiation
This method is also known as Lipophilic or oil based
What is Method B
This method requires a pre-rinse before the remover step
What is Hydrophilic method
This method has a tolerance to excess removal time
What is Method D Hydrophilic
solvent is the way this method is removed
what is Method C
2 minutes is the Emulsification dwell time for this FPI method
What is Method D:Hydrophilic
Using method B , the emulsification dwell time shall not exceed this limit
what is 5 minutes
This improves visibility of entrapped penetrant
What is Developer
the part temperature shall not exceed this when drying parts after penetrant application
What is 140 degrees F
contrast between an indication and its background is improved by the use of this
What is Developer
If a Discontinuity interferes with the part’s usefulness , it is classified as this
What is a defect
In-service, processing, Inherent are all examples of this
What are classifications of discontinuities
This is rounded dot indications, common to cast parts and welds, and not a defect unless extensive enough to cause weakness of structure
What is Porosity
This is the number of samples that must be taken from new batches of penetrant, emulsifier, remover and developer?
What is Two
Because this systems materials are not subject to reuse or contamination during use ,it does not require a 7 day system performance test
What is Solvent removable penetrant systems
This is an interruption in normal configuration of a part which may or may not affect the usefulness of the part
What is a Discontinuity
Prior processing or rework, the Geometry of part, or Improper processing can cause this
What is an inspection indication
This dwell mode is the preferred mode
What is Drain mode
While using UV-A lamps This What type of glasses shall be worn
What is UV filtering safety glasses
