Analyses of C, S, N and O by combustion and fusion techniques Analyses of H by fusion technique For scopes outside specified limit, please inquire. Individual reprints single or multiple copies of asttm standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm.
Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. Add to Alert PDF. It is assumed 1.
Signicance and Use 4.
If necessary, wash three times with acetone by decantation to remove organic contaminants and dry at room temperature. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Turn on the instrument and allow sufficient warm up time to stabilize the system. Blank values are equal to the total result from the crucible and Calibrant A minus the certied oxygen content of Calibrant A.
Prepare more capsules of sulfur solution H if necessary. We have no amendments or corrections for this standard. Note 22—The upper limit of the scope has been set at 0. During combustion, the IR absorption properties of CO and CO2 gases in the chamber cause a loss of energy; therefore a loss in signal results which is proportional to concentrations of each gas in the closed loop.
astk With large amount of test, please ask for a quotation. This distortion alters the xed capacitance, creating an electric signal change that is amplied for measurement as SO2. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.
The results should agree with the assigned value for Calibrant B within a range of 6 s, the standard deviation of a single determination e11019 Calibrant B using this method. Using a clean le or water cooled silicon carbide grinding media, abrade all surfaces of the sample to remove all traces of surface oxidation or other impurities, rinse in acetone, air-dry, and weigh.
NOTE 30—Repeat the calibration when 1 a different lot of crucibles is used, 2 a different lot e10199 accelerator is used, 3 the system has not been in use for 1 h, and 4 the oxygen supply has been changed. Use Calibrant C as the calibrant and analyze at least three test samples to determine the calibration slope. All use calibration methods traceable to certied reference materials. You sstm download and open this file to your own computer but DRM prevents opening this file on another computer, including a networked server.
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. No other units of measurement are included in this standard. NOTE 10—If the analyzer does not compensate for blank and sample weight values, then use the following formula: NOTE 28—The use aetm 1.
We have no document history for this standard. No other units of measurement are included in this standard. The aastm in Range III are from eight laboratories. This standard is also available to be included in Standards Subscriptions. Summary of Test Method Proceed to Checkout Continue Shopping. As written, this test method is not applicable to cast iron samples. During specimen combustion, the ow of SO2 with sstm oxygen gas carrier is routed through the measure chamber while oxygen alone passes through the reference chamber.
Repeat a sufficient number of times to establish that a low average blank value 0.
NOTE 1—The accelerator should contain no more than 0. Make a minimum of two determinations using a specimen and accelerator, as directed in Analyze at least three reference material specimens to determine calibration slope. Users of this atsm are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own wstm.
Alternatively, the weighed sample may be manually introduced into the outgassed crucible in Section In the absence of CO and CO2, the energy received by each detector is maximum. A number in parentheses indicates the aztm of last reapproval. In this case, laboratories should perform method validation using reference materials.
One cell is used as both a reference and a measure chamber. NOTE 9—This procedure is for analysis of steel samples and a new blank must be determined using 1.
This standard is subject to revision at any time by the responsible technical committee and must be reviewed every ve years and if not revised, either reapproved or withdrawn. Co-base analyses are mainly performed as analyses of steel. NOTE 6—The accelerator should contain asmt more than 0. Specific hazards statements are given in Section 6.
The absorption of infrared energy by the CO in the gas stream causes a reduction in the energy received at an infrared detector. Remove from furnace and cool in air for 90 6 15 s before use. Part of the IR sstm is absorbed by the SO2 present in the measure chamber while none is absorbed passing through the reference chamber.
Test Method B—The combustion is performed wstm a closed loop in which SO2 is detected in an infrared cell.
