In some cases, it is desirable to vapor degrease, then follow with a solvent soak. The developer shall be applied in a manner appropriate to the type of penetrant being used. Subtract the second reading from the?
Finally, rinse both inside and outside of the sample crucible into the beaker. This may be as little as 5 min or as much as 20 min. The procedures assume that bromine or iodine will not be present. Dye Penetrant Inspection is a means of locating fine cracks on the surface of parts by allowing a visible or fluorescent dye to accumulate in any such discontinuity to reveal its shape and location.
Sample dilution overcomes many interferences. Contact time shall be kept to the minimum time to obtain an acceptable background and shall not exceed asmt minutes. The developing agent draws the remaining penetrant out of the cracks to make them readily visible to an inspector. NOTE 10—With spray applications, it is important that there be proper ventilation.
Drying may be accomplished by warming the parts in drying ovens, with infrared lamps, forced hot air, or exposure to ambient temperature. The concentration of the emulsi? The soluble developer coatings simply dissolve off of the part with a water rinse.
ASTM E – Standard Practice for Liquid Penetrant Examination for General Industry
They can also be dusted with the powder developer through a hand powder bulb or a conventional or electrostatic powder gun. ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard. The full amount of these elements will not be reported.
Subscription pricing is determined by: The water spray pressure shall not exceed 40 psi [ kPa] when manual or hydro xstm spray guns are used. Fluorine will not be detected. Penetrant testing is a nondestructive testing method for detecting e15-09 that are open to the surface such as cracks, seams, laps, cold shuts, shrinkage, laminations, through leaks, or lack of fusion and is applicable to in-process,?
It will remove inorganic soils astk many organic soils from the surface of parts, but may not reach to the bottom of deep discontinuities, and a subsequent solvent soak is recommended. The maximum differential is taken as the end point. Its range of applicability is 0. These impurities may cause embrittlement or corrosion, particularly at elevated temperatures.

It should be pointed out, however, that after indications have been found, they must be interpreted or classi? Current edition approved June 15, Work Item s – proposed revisions of this standard. Blanks are prepared and analyzed in a similar fashion. You may delete a document from 1e65-09 Alert Profile at any time.
It is particularly important where residual penetrant testing materials might combine with other factors in e15-09 to produce corrosion and prior to vapor degreasing or heat treating the part as these 7 9. Small parts are quite often placed in suitable baskets and dipped into a tank of penetrant. Generally, minimum detectable concentrations are in the range of 0. Already Astn to this document. It provides a single instrumental technique for rapid, sequential measurement of common anions such as bromide, chloride,?
