Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. 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. Should the instrument be equipped for multi-point calibration, several additional calibration solutions should be analyzed to ensure error has not been introduced by the curve-?
Specimens shall be precipitation heat-treated after cutting and prior to testing. Copper deposition shall be considered completed, when no copper is deposited on a newly exposed surface. Should copper plate-out on the newly exposed cathode surface, dilute a second time and continue electrolysis for an additional 15 min.

A number in parentheses indicates the year of last reapproval. Spectrophotometric measurement is made at nm. E 29 Practice for Using Signi? This standard has been approved for use by agencies of the Department of Defense. Rinse the beaker several times with water and?
Allow the crucible to cool. b914
Add 50 mL of the mixed acid, g194 the beaker, and allow to stand until the reaction subsides. Cover the beaker with a pair of split cover glasses and electrolyze at a current density of about 0. Cool, transfer into a 1-L volumetric? An acidic solution of silicic or? Add mL of nitric acid HNO3.
Silicon present in the sample is converted to silicic or? Cool and wash down cover glass and inside of beaker. Cool, dilute to volume, and mix. Instrument response for each analyte element must be adequate to permit an estimation of analyte concentration to within 0.
It is n194 that all who use these test methods will be trained analysts capable of performing common laboratory procedures skillfully and safely. Aspirate the test solutions and record their absorbance.

This standard is subject to revision at any time by the responsible technical committee and must be reviewed every? Allow the crucible to cool, add 10 mL of water, and? C See Appendix X1.
Rinse the cathode in a water bath and then dip in two successive baths astk ethanol or acetone. 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-? Current edition approved Oct.
This specification establishes the requirements for plates, sheets, strips, and rolled bars of copper-beryllium alloy with Copper Alloy UNS Nos. The apparatus, standard solutions, and certain other reagents are referred to by number and shall conform to the requirements prescribed in Practice E F The upper limits in the tensile strength column are for design guidance only.
It is assumed that all who use these test methods will be trained analysts capable of performing common laboratory procedures skillfully and safely. Measure the absorbance of the solutions as directed in A1.
Limits for unnamed elements may be established, by agreement between manufacturer or supplier and purchaser.
