Historical (view previous versions of standard)
Significance and Use
These test methods compile in one place, recommended procedures for analysis of the pigment known commercially as calcium borosilicate. This pigment is used extensively in paints and the composition is important to the user and producer.
1.1 These test methods cover the analysis of the pigment commercially known as calcium borosilicate.
1.2 The test methods appear in the following order:
|Silicon Dioxide (SiO2)||6-9|
|Iron Oxide (Fe2O3)||10-13|
|Boron Trioxide (B2O3)||17-20|
|Calcium Oxide (CaO)||21-23|
|Moisture and Volatile Matter||24|
|Water of Hydration||25 to 26|
1.3 Individual specimens may be used for the direct determinations of SiO2, B2O3, and CaO. SiO2 and Fe2O3 should be removed before the determination of the B2O3 and CaO.
1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
