Significance and Use
These test methods may be used to confirm the stated strontium oxide and chromium oxide content of strontium chromate.
1.1 These test methods cover the chemical analysis of strontium chromate pigment.
1.2 The analytical procedures appear in the following order:
|Strontium by the Strontium Sulfate Method||7 to 10|
|Chromium by the Thiosulfate Method||11 to 14|
|Moisture and Other Volatile Matter||17|
|Mass Color and Tinting Strength||19|
