Last previous edition approved in as E — The value should agree with the assigned value for Calibrant C within a range of 6 s, the standard deviation of a single determination of Calibrant C using this method. The required amount is determined by the analyzer used, induction coil spacing, position of the crucible in the induction coil, age and strength of the oscillator tube, and type of crucible being sstm.
The use of small and irregular shaped samples requires a diligent effort to ensure that all surface contamination has been removed. Use Calibrant C as the primary calibrant and analyze at least three specimens to determine the calibration slope. Proceed to Checkout Continue Shopping. Specific hazards statements are given in Section 6.
NOTE 21—Careful adherence to the sample preparation procedures described above is critical to obtaining accurate and precise results. Treat each sample as directed in Proceed to Checkout Continue Shopping. 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 22—The upper limit of the scope has been set at 0. If they are not analyzed within four hours of preparation, repeat the ling step or grinding step prior to analysis.
NOTE 33—Although these test methods were tested to adtm 0.
About Us Contact Us. NOTE 26—The accelerator should contain no more than 0. Basic open hearth steel SRM 11h, 0. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. If not, repeat the steps given in No other units of measurement are included in this standard. 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.
NOTE 27—The uncertainty of results obtained using this test method is dependent on the uncertainty of the values assigned to the calibration reference materials. Current edition approved October 1, Samples must be of the proper size to permit free introduction into the sample loading device, if required, and to t in the graphite crucible.
Originally approved in If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below.
Cool in a desiccator. Prepare more capsules of sulfur solution B if necessary.

Total sulfur, as SO2, is monitored and measured over a period of time. We have no document history for this standard. The value should be within the allowable limits of atm certied value. Need more than one copy? A number in parentheses indicates the year of last reapproval. Remove from the furnace and cool in air for 90 6 15 s before use. Already Subscribed to this asrm. You may delete a document from your Alert Profile at any time.
If not, repeat Standards Subsctiption may be the perfect solution. Prepare the number of replicates indicated and then proceed as directed in Make a minimum of two determinations using a sample as directed in Section qstm to condition the instrument before attempting to calibrate the system or to determine the value of the blank.
No other units of measurement are included in this standard. During specimen combustion, the ow of SO2 with its oxygen gas carrier is routed through the measure chamber while oxygen alone passes through the reference chamber.
However, recognizing that commercial oxygen determinators are capable of handling higher concentrations, it may be that this test method can be used for oxygen concentrations outside of the scope. Please first log in with a verified email before subscribing to alerts. Analyze at least three reference material asttm to determine calibration slope. As written, this test method is not applicable to cast iron samples.
