Significance and Use
These test methods are suitable for determining the level of purity and for determining the levels of various impurities. They may be used to establish compliance with specification requirements.
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 D 215
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|
