Link to Active This link will always route to the current Active version of the standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. Transfer the solutions from the three beakers into individual plastic? It is expected that work will be performed in asttm properly equipped laboratory. It is the responsibility of the user of this standard to establish appropriate safety and health practices and to determine the applicability of regulatory limitations prior to use.

Copper remaining in the electrolyte is determined by atomic absorption spectrophotometry. Add 50 mL of the acid mixture to each? Especially avoid the inhalation of any beryllium-containing substance, either as a volatile compound or as a? Transfer each of the solutions into individual mL volumetric?

Cover the beaker, add 20 mL of HNO 3, and allow to stand until dissolution is nearly complete. This standard has been approved for use by agencies of the Department of Defense. Cool, transfer into a 1-L volumetric? ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date. Instrument response for each analyte element must be adequate to permit an estimation of analyte concentration to within 0.


Should the instrument be equipped for multi-point calibration, make sure that several additional solutions still are analyzed to ensure that error has not been introduced by the curve-? This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version.

A superscript epsilon e indicates an editorial change since the last revision or reapproval. Transfer the solution into a 1-L volumetric? Other heat treating temperatures and times may be preferred for end products of this material. Transfer a portion of the zero-calibration solution to a 1-cm pathlength spectrophotometer cell and adjust the instrument readout system to obtain zero absorbance.

Light the burner and aspirate water until the instrument reaches thermal equilibrium. These values apply to mill products Section The values given in parentheses are mathematical conversions to SI units, which are provided for information only and not considered standard.

Add ast, mL of HNO 3, 1 drop of? Add 25 mL of the boric acid solution to each of 8 mL plastic volumetric? Heavy pieces of metal should also be avoided, as they dissolve too slowly. Further thermal treatment is not normally required. Cool, dilute to volume, and mix.

ASTM B194 Grade C17000 TM01

Spectrophotometric measurement is made at nm. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

Cover the beaker and allow to stand until dissolution is nearly complete. Aspirate water between samples to?

Samples should be transferred to the spectrophotometer cell just prior to reading. Add to each beaker 0. The derived SI unit for force is the b1194 Nwhich is de? Aspirate the appropriate dilution of the reagent blank and the test solutions and record their absorbance readings.

Dilute to approximately mL and mix. While maintaining these adjustments, obtain the absorbance readings for the calibration solution, test solutions, and the background color solution using matched 1-cm pathlength cells.

C shall be the alloy furnished whenever Speci? Add 20 mL of the acid mixture. Allow the crucible to cool. Cover the beaker with a pair of split cover glasses and electrolyze at a current density of about 0. C shall be the alloy furnished. Cool to ambient, allowing the excess boric acid to recrystallize, and?

Boil to complete dissolution and expel brown fumes. Continue as directed in A1. Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phoneb149or service astm.

Cool the melt, dissolve completely in water, and dilute to 1 L in a plastic volumetric? Filter hot water through a?

Add two drops of HCl after the? It is assumed that all who use these test methods satm be trained analysts capable of performing common laboratory procedures skillfully and safely. Add aetm of nitric acid HNO3. The mechanical requirements of Table 3 do not apply to such special heat treatments.

This method of calibration may be used provided that additional calibration solutions are analyzed as samples to test for precision and linearity. Precipitation heat-treatment parameters for Table 2 and Table 3 are shown in Section
