Penetrant leak testing
| Глоссарий по тестированию |
- Technique of penetrant testing in which the penetrant is applied to one surface of a test material while the opposite surface is tested for indications that would identify a leak or void passing through the material thickness.
- Technique of penetrant testing in which leaker penetrant is applied to one surface of a test material while the opposite surface is tested for indications that would identify a leak or void passing through the material thickness. penetrant, liquid oxygen (lox) safe: penetrant material or system specifically designed to be compatible with or nonreactive in presence of liquid oxygen. penetrant, postemulsifiable: penetrant that requires the application of a separate emulsifier to render the excess surface penetrant water washable. see also emuslifier; soak time. penetrant system monitor (psm): stainless steel panel that is used for regular penetrant system verification to show that test sensitivity has not degraded with time. the penetrant system monitor panel is 100 mm (4 in.) wide = 150 mm (6 in.) long = 1.16 mm (0.085 in.) thick and is divided into two vertical halves. one half is chrome plated, which may or may not be media blasted, and contains five radial cracks of increasing size. the other half is media blasted and acts as a penetrant removability tool. this panel is not designed to be a penetrant sensitivity check. also called star burst panel or tam panel. compare comparator; known discontinuity standard; known discontinuity standard, nickel-chrome. penetrant testing (pt): also known as liquid penetrant testing; pt. nondestructive test method using a liquid that can enter discontinuities open to the test surface. when drawn into a layer of developer, the liquid is highly visible in small traces. fluorescent penetrants fluoresce brightly under ultraviolet radiation whereas color contrast penetrants are intensely colored to be readily visible on developer backgrounds when illuminated with visible light. see also color contrast penetrant; penetrant testing, fluorescent. penetrant testing, fluorescent: inspection technique that uses a dyed fluid that is usually green in color and fluoresces brilliantly under ultraviolet radiation. the sensitivity of a fluorescent penetrant depends on its ability to form indications that appear as small sources of light against a dark background. also known as fluorescent penetrant inspection (fpi). penetrant, water washable: penetrant with built in emulsifier that makes it directly removable with a water spray.

- An additive that promotes the formation of a stable emulsion, usually of oil and water.
- A substance that promotes the formation of a stable emulsion. in industrial maintenance cleaning, emulsifiers are used to modify the surface tension of liquid droplets (dispersed phase) to keep them from coalsecing (agglomerating); the resulting emulsion suspends soil in solution.
