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 cautiously add mL of nitric acid HNO3 in small increments. Grain count shall be determined in a plane perpendicular to the surface and perpendicular to the direction of rolling. A superscript epsilon e indicates an editorial change since the last revision or reapproval. D Elongation requirement applies to material 0.

Transfer by pipet 50 mL of the copper stock solution into each? Obtain the net absorbance for each calibration solution by subtracting the average absorbance for the zero-calibration solution from the average absorbance of each of the calibration solutions.

Spectrophotometric measurement is made at nm. Cool, wash down the cover glass and inside of the beaker. Specimens shall adhere to specified chemical composition, grain size, and grain count requirements. Aspirate the test solutions and record their absorbance.

Repeat all measurements a minimum of two times. These solutions are equivalent to 0. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. Light the burner and aspirate water until the instrument reaches thermal equilibrium.

Cover with mL of water. Cool, transfer into a 1-L volumetric? This abstract is a brief summary of the referenced standard. Let stand for 10 min. 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. Rinse the watch glass and inside of the beaker with water. 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.

Last previous edition B — Materials shall be processed by the following conditions: Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. It is expected that work will be performed in a properly equipped laboratory.

Copper deposition shall be considered completed, when no copper n194 deposited on a newly exposed surface. When dissolution is complete, add 25 mL of boric acid solution to three mL plastic? Precipitation heat-treatment parameters for these bend tests shall be in accordance with Mechanical Property Requirements 8. The apparatus, standard solutions, and certain other reagents are referred to by number and shall conform to the requirements prescribed in Practice E To pass the bend test, at least four specimens out of?

Copper is electrolytically deposited on a tared platinum cathode. Aspirate the appropriate dilution of the reagent blank and the test solutions and record their absorbance readings. 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. To the 8 volumetric?

This method of calibration may be used provided additional calibration solutions are analyzed as samples to test for the precision and linearity. To seven of the?

Instrument response must be adequate to permit an estimation of silicon to within 0. Add 20 mL of water and cover with a watch glass. The mechanical requirements of Table 3 do not apply to such special heat treatments. It is assumed that all who use these test methods will be trained analysts capable of performing common laboratory procedures skillfully and safely. 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.

Users of this standard 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 responsibility.

The following alloys are specified: F The upper limits in the tensile strength column are for design guidance only. Hardness values shown apply only to direct determinations, not converted values.

Samples should be transferred to the spectrophotometer cell just prior to reading. 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. Cover the beaker, add 20 mL of HNO 3, and allow to stand until dissolution is nearly complete.
