Maujind A minimum of three reference materials shall be used for each element. Avoid the center of cast specimens because there is more chance of quench cracks and segregation. Department of Commerce, Gaithersburg, MD The samples must be sufficiently massive to prevent overheating during aatm discharge and of a similar metallurgical condition and composition as the reference materials. Link ee1086 Active This link will always route to the current Active version of the standard. Asttm resulting surface should be uniformly plane and free of defects. Standardization will be done anytime veri? This represents a total of 15 determinations. A variety of such systems are commonly used. Any of these that will achieve analytical accuracy equivalent to that reported for this test method are acceptable. The precision data for the three unknowns is shown ast, Table 2. Precision and Bias 2 Cracks, voids, pits, moisture, or inclusions will limit the sampling and the accuracy of a determination. Grinding materials with grit sizes ranging from 60 to have been found satisfactory. The ring is placed on a?

Precision and Bias 2 Cracks, voids, pits, moisture, or inclusions will limit the sampling and the accuracy of a determination. Grinding materials with grit sizes ranging from 60 to have been found satisfactory. The ring is placed on a? Successive excitations shall be sufficiently separated so that the discharge patterns do not overlap. The interlaboratory testing was conducted in accordance with Practice E This procedure is suitable for manufacturing control and inspection testing.

Position the specimen so there will be a uniform pattern of excitations around its face.

It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the astj of regulatory limitations prior to use. The radiant energy of selected analytical lines are converted into electrical energies by photomultiplier tubes and stored on capacitors.

If you feel that your comments have not received a fair hearing atm should make your views known to the ASTM Committee on Standards, at the address shown below. If the readout is not in direct concentration units, use this value to obtain the concentrations from the curves, or related scale values and concentration by reference to a table that has been previously prepared.

Make the necessary corrections either by adjusting the controls on the readout or by applying arithmetic corrections. Standardization will be done anytime veri? Analyze veri? If con? If readings are not in conformance, repeat the standardization.

Procedure for Excitation and Radiation Measurement 12. Place the freshly surfaced specimen on the excitation stand in a manner to effect a gas-tight seal and adequate argon? Position the specimen so there will be a uniform pattern of excitations around its face. For example, a disk-shaped specimen should have a ring of excitation marks around its outer edge and approximately 6 mm 0. Avoid the center of cast specimens because there is more chance of quench cracks and segregation.

Make a good electrical ground. Cool the specimen after two excitations to prevent overheating, if required. Examine the specimen after each excitation to evaluate the quality of excitation.

Cracks, voids, pits, moisture, or inclusions will limit the sampling and the accuracy of a determination. Successive excitations shall be sufficiently separated so that the discharge patterns do not overlap.

Calculation of Results 13. If the readout is not in direct concentration units, use this value to obtain the concentrations from the curves, or related scale values and concentration by reference to a table that has been previously prepared.

F d-c charged Inductance,? F Inductance,? H Resistance, V Potential, V 7.

Calibration, Standardization, and Veri? A veri?

There shall be at least three calibrants for each element, spanning the required concentration range. Repeat with different random sequences at least four times. Follow the procedure for the concentration-ratio method in accordance with Practice E 158.

E 1086 — 94 2005 14. Precision and Bias 2 14. The interlaboratory testing was conducted in accordance with Practice E 1060.

Using reference materials supplied with the unknowns, in-house reference materials, NBS and British Certi? The precision data for the three unknowns is shown in Table 2.

The agreement between the results obtained by chemical methods and those obtained by this test method is displayed in Table 3. Spectrometer characteristics for two of the instruments used in this test method are described as having dispersion of 0. Spectral lines are listed in Table 1. Silver or thoriated tungsten rods are typically used.

Other material may be used provided it can be shown experimentally that equivalent precision and accuracy are obtained. These reference materials shall be homogeneous, and free of voids or porosity. A minimum of three reference materials shall be used for each element.

Preparation of Samples 9. A specimen cut from a large sample section must be of sufficient size and thickness for preparation and to properly fit the spectrometer stand.

A Silicon 251. Phosphorus 178. Interference corrections will not be necessary if: separate silicon and phosphorus curves are used for 316 and 317 alloys; the manganese content varies only between 0. B Either iron line 271.

Iron 271. Grind the surface with an abrasive belt or disc. Refer to 6. Perform the final grind with a dry abrasive belt or disc.

ASTM E | Steel | Accuracy And Precision

Preparation of Apparatus 10. Typically, every 4 h to 8 h is practical and adequate or if the instrument has been idle for more than 1 hour. If the results are not within the control limits established in 12. Repeat standardization as necessary so verifications are within control limits or investigate further for instrument problems.
