1.1 These test methods cover procedures for the chemical analysis of basic carbonate white lead and basic sulfate white lead.
Note 1: If it is necessary to separate these pigments from others, refer to Practice D215.
1.2 The analytical procedures appear in the following order:
|Preparation of Sample||6|
Basic Carbonate White Lead:
|Small Amounts of Iron||7|
|Moisture and Other Volatile Matter||9|
|Carbon Dioxide (Evolution Method)||10|
|Carbon Dioxide and Combined Water (Combustion Method)||11|
|Total Matter Insoluble in Acetic Acid||13|
|Total Matter Insoluble in Acid Ammonium Acetate||14|
|Total Impurities Other Than Moisture||15|
Basic Sulfate White Lead:
|Small Amounts of Iron||17|
|Moisture and Other Volatile Matter||19|
|Basic Lead Oxide||22|
