The mercurous nitrate crystals are photosensitive and when they have turned yellow are difficult to dissolve. They shall be free of oil and grease, acid, dirt, grit of any kind, and shall be clean and bright. NOTE 1—Because of the discontinued nature of the processing of 9. Mercury, or its vapor, may be hazardous to health and corrosive to materials. Government, any sample unit having Copper E one or more defects shall be rejected.
For any particular copper alloy, reference should be made to the material specification. Government Contracts NOTE 1—If the number of original castings from which the material is processed is less than the number of samples specified, not more than one sample need be taken from each piece for chemical analysis.
Add the water in small portions while stirring to prevent local overdilution. Temper Aztm Min Max Originally published as B 19 — 19 T. Copper, inclusive, except material for 20 mm disks, shall be furnished when determined by difference, must conform to the require- to a grain size of 0.
Repeat this procedure with 50 mL of a standard 1 weight per volume percent of HgNO3 solution.
