In accordance with BS EN ISO 3059 the minimum level of white light illumination for visible techniques is:

• 500 lux

• 200 lux

• 800 lux

• 1000 lux

Background coloration will reduce sensitivity of a dye penetrant inspection. It is due to:

• The natural colour of the component.

• Incomplete removal of penetrant.

• Lack of contrast between penetrant and developer.

• Inadequate contrast between component and work piece.

Methods of assessing overall process capability include:

• Cracked components.

• Quench cracked aluminium blocks.

• Slotted blocks.

• Both a and b are correct.

Which penetrant is best suited for overhead work?

• Filtered particle.

• Dual sensitivity.

• Thixotropic.

• Water washable

Drainage time is:

• The time allowed for drainage of applied fluids.

• The time taken for test tanks to clear.

• Time taken for penetrant to draw from defects.

• The time for which a component is submerged.

A definition of hydrophilic remover is:

• Water based and miscible in all proportions with water.

• Oil based and miscible in all proportions with post-emulsifiable penetrant.

• Water heating.

• Using water for penetrant removal.

Which document gives information on exposure limits for hazardous substances?

• HSE.

• COSHH.

• EH40.

• None of the above.

Which of the following would define a substance that is hazardous to health?

• HSE.

• COSHH.

• EH40.

• None of the above.

The first requirement of COSHH is to prevent exposure to substances hazardous to health. This may be achieved by:

• Completely enclosing the process

• Changing the process so that the substance is no longer used

• Replacing substances with safer alternatives

• All of the above

The purpose of vapour degreasing is to remove:

• Oils, greases and organic solids.

• Slag,rust and oxides.

• Paint and dust.

• Dye penetrant prior to development.
