Standard Practices for Apparatus, Reagents, and Safety Considerations for Chemical Analysis of Metals, Ores, and Related Materials

Importancia y uso:

4.1 The inclusion of the following paragraph, or a suitable equivalent, in any standard (preferably after the section on Scope) is due notification that the apparatus and reagents required in that standard are subject to the recommendations prescribed in these practices.

 

“Apparatus and Reagents—Apparatus and reagents required for each determination are listed in separate sections preceding the procedure. Apparatus, standard solutions, and certain other reagents should conform to the requirements prescribed in E01 Practices E50, for Apparatus, Reagents, and Safety Considerations for Chemical Analysis of Metals, Ores, and Related Materials.”

 

(A) For concentration of laboratory reagent, see Table 2.

† ACS specification exists but does not cover all requirements.

* Reagent on which ACS specifications exist.

(B) Contains at least 50 % H₃PO₂.

4.2 It is assumed that the users of these practices will be trained analysts capable of performing common laboratory procedures skillfully and safely. It is expected that work will be performed in a properly equipped laboratory.
