When agreed upon by the contracting parties, the e1655-09 piece may contain real or simulated discontinuities, providing it displays the characteristics of the discontinuities encountered in product examination.
Tag: ASTM E165-09
Summary of Practice 4. A satisfactory method for doing this is to rotate the bomb in a lathe at about rpm and polish the inside surface with Grit No.
The water spray pressure shall not exceed 40 psi [ kPa] when manual or hydro air spray guns are used. NOTE 12—The vapors from the volatile solvent carrier in the developer may be hazardous. SI units are provided for information only. The chlorine compounds thus liberated are absorbed in a sodium carbonate solution and the amount of chloride present is determined 9 titrimetrically either against silver nitrate with the end point detected potentiometrically Method A or coulometrically with the end point detected by current?
It will not remove inorganic-type soils dirt, corrosion, salts, etc. Wash down the sides of the bomb shell with water, using a wash bottle. All of these contaminants can prevent the penetrant from entering discontinuities see Annex on Cleaning of Parts and Materials.
With a system requiring suppressor regeneration, NO2? Its range of applicability is 1 to ppm. This may be as little as 5 min or as much as 20 min.
After the parts are removed from the developer bath, allow the parts to drain. Insoluble residue after combustion will entrain? 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.
In this type of system the water dip see Note A4. Table 2, however, provides a guide for selection of penetrant dwell times for a variety of materials, forms, and types of discontinuities. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters.
Because of the short contact time, degreasing may not completely clean out deep discontinuities and a subsequent solvent soak is recommended.
Stir to dissolve and then adjust the pH to 5. It is recommended to not e156-09 oxygen or ignite the sample if the bomb has been jarred, dropped, or tilted. To prevent removal of penetrant from discontinuities, care should be taken to avoid the use of excess solvent.
Astn the second reading from the? A family of liquid penetrant examination materials consists of the applicable penetrant and emulsi?
The procedure should be quali? Penetrant testing is 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 satm fusion and is applicable to in-process, final, and maintenance testing.
The cleaning properties of detergent solutions facilitate complete removal of soils and contamination from the surface and void areas, thus preparing them to absorb the penetrant. For example, relatively high concentrations of lowmolecular-weight organic acids interfere with the determination of chloride and? Developing time begins immediately after the application of dry powder developer or as soon as the wet aqueous or nonaqueous developer coating is dry that is, the water or solvent carrier has evaporated to dryness.
Chromate interferes with the procedures, causing low or nonexistent end points. The spray rinse time shall be less than two minutes, unless otherwise speci? Some penetrants are less resistant to adtm than others, so caution should be exercised. Proceed to Checkout Continue Shopping. E15-09 in plastic bottles in a refrigerator; these solutions are stable for at least one month.
This standard is subject to revision at any time by the responsible technical committee and must be reviewed every?
The method selected will depend accordingly on the design and service requirements of the parts or materials being tested.
You can download and open this file to your own computer but DRM prevents opening this e16-09 on another computer, including a networked server. Water suspendable developers Form C can be used ast both Type 1 and Type 2 penetrants. It can be removed manually with a coarse spray or wiping the part surface with a dampened rag, automatic or semi-automatic water-spray equipment, or by water immersion. Other materials may contain impurities, which are not volatile and may react with the part, particularly in the presence of moisture or elevated temperatures.
It is recommended to not use more than 1 g total of sample and white oil or other chlorine-free combustible material.
ASTM E / EM – 12 Standard Practice for Liquid Penetrant Examination for General Industry
Materials used in the bomb assembly, such as the head gasket and leadwire insulation, shall be resistant to heat and chemical action, and shall not undergo any reaction that will affect the? Record the peak height or area and retention time to permit calculation of the calibration factor, F. Washings should equal but not exceed mL. The total amount of AgNO3 solution required to produce this maximum differential is the end point.
The developing agent draws the remaining penetrant out of the cracks to make them readily visible to an inspector.
The intensity shall be checked daily to ensure the required output see Guide E for more information. All areas of this practice may be open to agreement between the cognizant engineering organization and the supplier, or speci? Longer times may be necessary under some circumstances.

Next, rinse the bomb cover and terminals into the beaker. Maximum development time in accordance with 8.
