Follow normal procedure, making two or three test runs to be sure the results are within the limits of repeatability for the test. Agreement by the customer requesting penetrant inspection e15-09 strongly recommended.
NOTE 8—Surface preparation of structural or electronic ceramics for penetrant testing by grinding, sand blasting and etching is not recommended because of the potential for damage.
Satisfactory inspection results can usually be obtained on surfaces in the as-welded, as-rolled, as-cast, as-forged, or ceramics in the densi? It should be pointed out, however, that after indications have been found, they must be interpreted or classi? Visible penetrant indications must be viewed under adequate white light.
The dried developer coating appears as a translucent or white coating on the part. For this purpose there must be a separate code, standard, or a specific agreement to define the type, size, location, and direction of indications considered acceptable, e16-509 those considered unacceptable. The remaining traces should be removed with the solvent remover see 8.
The developing agent draws the remaining penetrant out of the cracks to make them readily visible to an inspector. Each of the various penetrant methods has been designed for specific uses such as critical service items, volume of parts, portability or localized areas of examination. Combining values from the two systems may result in non-conformance with the standard.
Keep the remainder in a refrigerator, but do not freeze.
Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. The sample is oxidized by combustion in a bomb containing oxygen under pressure. When agreed upon by the contracting parties, the test piece may contain real or simulated discontinuities, providing it displays the characteristics of the discontinuities encountered awtm product examination.
The asrm will keep for about six months in the refrigerator.

Redevelopment time shall be a minimum of ten minutes, except nonaqueous redevelopment time should be a minimum of three minutes. Next, rinse the bomb cover and terminals into the volumetric? With a system requiring suppressor regeneration, NO2? If only a section of a part, such as a weld, including the heat affected zone is to astk examined, all contaminants shall be removed from the area being examined as de? If iodine is present, If the sample is a solid, add a few drops of white oil at this time to ensure ignition of the sample.
Flushing the surface 1e65-09 solvent following the application of the penetrant and prior to developing is prohibited. If the indication does not reappear, the original indication may be considered false.
Any necessary touch-up rinse after an immersion rinse shall meet the requirements of 8. Photochromic or tinted lenses shall not be worn during the processing and examination of parts.

E165-0 areas of this practice may be open to agreement between the cognizant engineering organization and the supplier, or speci? Any such evaluation shall also include consideration of the form in which the impurities are present. Fluorescent indications are many times brighter than their surroundings when viewed under appropriate black light illumination. After each use, they should be scrubbed out with?
These developers will form a transparent or translucent coating on the surface of the part. Permission rights to photocopy the standard may also be secured from the ASTM website www.
Contact time shall be kept to the minimum time to obtain an acceptable background and shall not exceed three minutes. All parts or areas of parts to be examined must be clean and dry before the penetrant is applied.
Originally approved in Spray parts in such a manner as to ensure complete part coverage of the area being examined with a thin, even? Electrostatic spray application can eliminate excess liquid build-up of penetrant on the part, minimize overspray, and minimize the amount e165-009 penetrant entering hollow-cored passages which might serve as penetrant reservoirs, causing severe bleedout problems during examination.

Do not use more than 1 g total of sample and white oil or other? Active view current version of standard.
The developer shall be applied in a manner appropriate to the type of penetrant being used. It is desirable, however, that the bomb be enclosed in a shield of steel plate at least 1?
A suitable technique, such as a simple water rinse, asfm spray, machine wash, solvent soak, or ultrasonic cleaning may be employed see Annex A1 for further information on post cleaning.
Automatic titrators e165–09 stir the sample, add titrant, measure the potential difference, calculate d165-09 differential, and plot the differential on a chart. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Using a prewashed syringe of 1 to 10 mL capacity equipped with a male luer?
Some solid additives are relatively insoluble, but may be satisfactorily burned when covered with a layer of white oil.
The separated anions in their acid form are measured by conductivity. The sample weight should not exceed 0.
