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:

Test Methods Sections Silicon Dioxide (SiO2) 6 to 9 Iron Oxide (Fe2O3) 10 to 13 Boron Trioxide (B2O3) 17 to 20 Calcium Oxide (CaO) 21 to 23 Moisture and Volatile Matter 24 Water of Hydration 25 to 26 Coarse Particles 27 Oil Absorption 28

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 This standard does not purport to address the safety problems 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.
