If the results are not within the control limits established in Place the freshly surfaced specimen on the excitation stand in a manner to effect a gas-tight seal and adequate argon flushing. One or more of the reference materials must closely approximate the composition of the specimen. Make a good electrical ground. The technique of analyzing reference materials with unknowns and performing the indicated mathematical corrections may also be used to correct for interference effects and to compensate for errors resulting from instrument drift.
Excitation and Integration Link to Active This link will always route to the current Active version of the standard. For example, a disk-shaped specimen should have a ring of excitation marks around its outer edge and approximately 6 mm 0. If the spectrometer system and software permits, perform random excitations of each calibrant and drift correction sample and repeat with different random sequences at least four times.
Calculation of Results Spectrometer characteristics for two of the asgm used in this test method are described as having dispersion of 0. Originally approved in Calibration, Standardization, and Verification A specimen cut e10086 a large sample section must be of sufficient size and thickness for preparation and to properly fit the spectrometer stand.
The interlaboratory testing was conducted in accordance with Practice E Any of these that will achieve analytical accuracy equivalent to that reported for this test method are acceptable. Keywords the testing of this test method. The samples must be sufficiently massive to prevent overheating during the discharge and of a similar metallurgical condition and composition as the reference materials. Last previous edition approved in as E — The flow rate may be manually or automatically controlled.
Reagents and Materials 7. Examine the specimen after each excitation to evaluate the quality of excitation. Position the specimen so there will be a uniform pattern of excitations around its face.

Link to Active This link will always route to the current Active version of the standard. Please fill this form, we will try to respond as soon as e11086. There shall be at least three calibrants for each element, spanning the required concentration range.
If required, cool the specimen after two excitations to prevent overheating. Procedure for Excitation and Radiation Measurement Flush, s Preburn, s Integration, s 3 7 20 20 Other material may be used provided it can be shown experimentally that equivalent precision and accuracy are obtained.

Spectral lines are listed in Table 1. Instrument calibrations were performed utilizing 1 reference materials supplied with the unknowns, 2 in-house reference materials, and 3 NIST and British Certified e10086 materials. Grind the surface with an abrasive belt or disc.
This procedure is suitable for manufacturing control and inspection testing. A variety of such systems are asm used. The precision data for the three unknowns are shown in Table 2. Make the necessary corrections either by adjusting the controls on the readout or by applying arithmetic corrections.
We need your help to maintenance this website. The discharge is terminated at a predetermined level of accumulated radiant energy from the internal standard iron line or after a fixed integration time. The argon system shall be in accordance with Practice E
