Reserve one portion for measurement of the background color and treat the remaining two in accordance with A1. The determinations are made on the separate samples and in a plane perpendicular to the surface and perpendicular to the direction of rolling. The following alloys are speci? Because it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate.

F The upper limits in the tensile strength column are for design guidance only. Cool, wash down the cover glass and inside of the beaker. Hardness values shown apply only to direct determinations, not converted values. Transfer each of the solutions into individual mL volumetric? Spectrophotometric measurement is made at nm. Rinse the beaker several times with water and?

Measure the absorbance as described in A1. Cover the beakers with TFE-? Let stand for 1 to 2 min to allow nitrogen to escape. Add 5 mL of HNO 3, 1 drop of?


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. Samples should be transferred to the spectrophotometer cell just prior to reading.

The absorption of the resonance line energy speci? 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-? It is expected that work will be performed in a properly equipped laboratory. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. For the purpose of determining conformance to speci?

Cover with mL of water. These solutions are equivalent to 0. Store in plastic container. Transfer the solution into a 1-L volumetric? Specimens shall adhere to specified chemical composition, grain size, and grain count requirements.

Repeat all measurements at least two times. Repeat all measurements a minimum of two times. Wavelength, nm Copper Cover the beaker with a pair of split cover glasses and electrolyze at a current density of about 0.

A small amount of? Originally published as B — 45 T. 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.

Further thermal treatment is not normally required. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. Last previous edition B — Rinse the cathode in a water bath and then dip in ast, successive baths of ethanol or acetone.

The proper precautions are to be observed in the disposition of beryllium-containing residues, especially ignited oxide. Continue as directed in B1994.

This method may be used, provided additional calibration solutions are analyzed as samples to test for precision and linearity.

Copper is electrolytically deposited on a tared platinum cathode.

Boil to expel the brown fumes. When dissolution is complete, add b1194 mL of boric acid solution to three mL plastic? Cover the beaker and allow to stand until dissolution is nearly complete. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters.
