Contact with the emulsi? The method selected will depend accordingly on the design and service requirements of the parts or materials being tested. Spurious peaks may result from contaminants in reagent water, glassware, or sample processing apparatus.
NOTE 12—The vapors from the volatile solvent carrier in the developer may be hazardous. It should be pointed out, however, that after indications have been found, they must be interpreted or classified and then evaluated. This standard is also available to be included in Standards Subscriptions.
SI units are provided for information only. E615-09 should be taken not to contaminate the developer with?
Use of a sample weight containing over 20 mg of chlorine may cause corrosion of the bomb. It is therefore extremely important to exercise proper control in the removal of excess surface penetrant to ensure against overwashing.
When a sample high in A2. The sample weight should not exceed 0. 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.
Excess developer powder may be removed by shaking or tapping the part, or by blowing with low-pressure dry, clean, 6 compressed air not exceeding 5 psi [34 kPa]. Because of the astmm contact time, degreasing may not completely clean out deep discontinuities and a subsequent solvent soak is recommended.
If the sample is solid, not more than 0. NOTE 14—Certain high-intensity black atm may emit unacceptable amounts of visible light, which can cause? The water spray pressure shall not exceed 40 psi [ kPa] when manual or hydro air spray guns are used. Application methods include dipping, brushing,?

Arrange the coil so that it will be above and to one side of the sample cup. Work Item s – proposed revisions of this standard. Any such evaluation shall also include consideration of the form in e165-099 the impurities are present. Penetrant testing astn a nondestructive testing method for detecting discontinuities 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, final, and maintenance testing.
ASTM E – Standard Practice for Liquid Penetrant Examination for General Industry
Wash down the sides of the bomb shell with water, using a wash bottle. These solvents should be residue-free, especially when used as a hand-wipe solvent or as a dip-tank degreasing solvent. Ambient light shall not exceed 2 fc [ Agreement by the customer requesting penetrant inspection is strongly recommended.
If the indication does not reappear, the original indication may be considered false. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. 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. Washings should equal but not exceed mL. Some solid additives are relatively insoluble, but may be satisfactorily burned when covered with a layer of white oil.
Spray parts in such a manner as to ensure complete part coverage of the area being examined with a thin, even? Some penetrant materials contain signi?

It is not necessary to prerinse a part if a spray application of emulsi? After a pre-determined interval the excess penetrant is removed and a developing agent is applied to the surface. Redevelopment time shall be a minimum of ten minutes, except nonaqueous redevelopment time should be a minimum of three minutes.

It will remove inorganic soils and 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.
For visible dye, the developer must be applied thickly enough to provide a contrasting background. It can be effectively used in the examination of nonporous, metallic materials, ferrous and nonferrous metals, and of nonmetallic materials such as nonporous glazed or fully densified ceramics, as well as certain nonporous plastics, and glass.
NOTE 5—Aqueous developers may cause stripping of indications if not properly applied and controlled. Admit oxygen see Note A4.
A test piece containing one or more discontinuities of the smallest relevant size is generally used. NOTE 4—While approved penetrant materials will not adversely affect common metallic materials, some plastics or rubbers e15-09 be swollen or stained by certain penetrants. Store in plastic bottles in a refrigerator; these solutions are stable for at least one month. The amount of time the part is in the bath should be the minimum required to remove the emulsi?
Finally, add wash solution to bring the contents of the? Visible penetrant indications must be viewed under adequate white light. Satisfactory inspection results can usually be obtained on surfaces in the as-welded, as-rolled, e165-90, as-forged, or ceramics in the densi?
