11. The gas penetrates smaller openings than the liquids used in dye penetrant inspection and fluorescent penetrant inspection. 12. The gas penetrates smaller openings than the liquids used in dye penetrant inspection and fluorescent penetrant inspection. 13. The peculiar nature of O-linked glycopeptides is that there are numerous examples which are CNS penetrant . 14. It has been linked to autosomal dominant, fully penetrant , nonsyndromic sensorineural progressive low-frequency hearing loss. 15. The penetrant is allowed " dwell time " to soak into any flaws ( generally 5 to 30 minutes ). 16. The dwell time mainly depends upon the penetrant being used, material being tested and the size of flaws sought. 17. Sometimes an annulus can be " " offset " ", meaning that the penetrant is not centred. 18. Also, the removal of excessive penetrant is done towards one direction either vertically or horizontally as the case may be. 19. Emulsifiers represent the highest sensitivity level, and chemically interact with the oily penetrant to make it removable with a water spray. 20. The developer draws penetrant from defects out onto the surface to form a visible indication, commonly known as bleed-out.
