Wipe off any excess mercury from the surface of the specimen. Repeat this procedure with 50 mL of a standard 1 weight per volume percent of HgNO3 solution. Used solutions may be replenished as described in 6.
This standard has been approved for use by agencies of the Department of Defense. Warning—Mercury is a de? In case specimen length, the necessary pieces of original material shall of dissatisfaction with the results of the tests, the producer or be prepared and annealed with the disks that these samples are supplier may make claim for a rehearing with this time period. They shall be free of oil and grease, acid, dirt, grit of any kind, and shall be clean and bright.
After solution is complete, use a small volume of retained dilution water to rinse the watch glass into the container. Enter the email address you signed up with and we’ll email you a reset link. NOTE 2—If heating is used in either of the previous procedures, the container should be covered with a watch glass to prevent loss of HNO3 and water to the atmosphere. Summary of Test Method 4.

ASTM B – 16 – Standard Test Method for Mercurous Nitrate Test for Copper Alloys
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. For any particular copper alloy, reference should be made to the material specification. After the crystals are completely dissolved, dilute the solution with 4 Reagent Chemicals, American Chemical Society Speci?

Specimen Preparation The minimum weight of the composite sample that is to be Active view current version of standard.
Add the water in small portions while stirring to prevent local overdilution. Lead E AA This gradual dilution, together with the excess acid, will prevent precipitation of basic salts of mercury. A number in parentheses indicates the year of last reapproval.
Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. Skip to main content. Inspection Grain Size, mm The mercurous nitrate crystals are photosensitive and when they have turned yellow are difficult to dissolve. Warning—The mercurous nitrate crystals are obtainable in both the monohydrate and dihydrate form and should be handled with caution because of their highly toxic effects. Grain Size Requirements castings into wrought products, it is not always practical to identify a specific casting analysis with a specific quantity of finished material.
If the manufacturer determines the chemical composition of the material during the TABLE 8 Permissible Variation in Thickness of Disks Blanks course of manufacture, he shall not be required to sample and Permissible Variations g154 analyze the finished product. The values given in parentheses are for information only. ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard.
