Mean salt method, description

K) Sodium salts, are detd gravimetrically by means of magnesium uranyl acetate reagent, using a 20g sample. As this, rather tedious method, is essentially the same as described in the literature(See Ref 3,pp 879-81 and Ref 8,pp 558-60), no description is given here... 

This appendix contains details for the method which has been tested at the OSHA Analytical Laboratory in Salt Lake City. Inclusion of this method in the appendix does not mean that this method is the only one which will be satisfactory. Copies of descriptions of other methods available are available in the rulemaking record, and may be obtained from the OSHA Docket Office. These include the Union Carbide, Dow Chemical, 3M, and DuPont methods, as well as NIOSH Method S-286. These methods are briefly described at the end of this appendix.
