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 (SiO
|6 - 9|
| Iron Oxide (Fe
|10 - 13|
| Boron Trioxide (B
|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 standard. No other units of measurement are included in this standard.
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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
