After the reaction subsides, rinse the watch glass and inside of the beaker with water and dilute to approximately mL. Cautiously add 35 mL of HNO3 in small increments. It is expected that work will be performed in a properly equipped laboratory.

Cover the beaker, add 20 mL of HNO 3, and bb194 to stand until dissolution is nearly complete. Limits for unnamed elements may be established, by agreement between manufacturer or supplier and purchaser. Measure the absorbance of the solutions as directed in A1. 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-?

Reserve one portion for measurement of the background color and treat the remaining two in accordance with A1. To seven of the? B1944 values shown apply only to direct determinations, not converted values.

In all cases only the current version of the standard as published by ASTM is to be considered the official document.


Cool, transfer into a 1-L volumetric? C shall be the alloy furnished. The determinations are made on the separate samples and in a plane perpendicular to the surface and perpendicular to the direction of rolling.

Add 20 mL of water and cover with a watch glass. This method may be used, provided additional calibration solutions are analyzed as samples to test for precision and linearity.

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. Add 20 mL of the acid mixture.

Measure the absorbance as described in A1. Cool to ambient, allowing the excess boric acid to recrystallize, and? Transfer each of the cool solutions from the beakers into individual volumetric? A superscript epsilon e indicates an editorial change since the last revision or reapproval.

The values given in parentheses are mathematical conversions to SI units that are xstm for information only and are not considered standard.

Alloys shall also undergo tensile and bend tests to evaluate their conformance to tensile strength, yield strength, elongation, and Rockwell hardness requirements. Rinse the watch glass b149 inside of the beaker with water.

Allow the crucible to cool. 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.


Because it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. Add to each beaker 0. Transfer each of the solutions into individual mL volumetric? Further thermal treatment is not normally required. F The upper limits in the tensile b19 column are for design guidance only. Add 5 mL of HNO 3, 1 drop of?

Cool, wash down the cover glass and inside of the beaker. Cool, dilute to volume, and mix. A small amount of?

Place the crucible on a hot plate and slowly evaporate just to dryness. Instrument response for each analyte element must be adequate to permit an estimation of analyte concentration to within 0. Mechanical Property Requirements 8. Add 25 mL of the boric acid solution to each of 8 mL plastic volumetric? Let stand for 10 min. These values apply to mill products Section Therefore, it is necessary to have the same amount of copper, 6 mg, present in the?

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.
