58,00 €

Details

1.1 ,This guide covers the determination of the particle size distribution of pulverized alumina and quartz for particle sizes from 45 to 5 μ,m by wet sieving.

1.2 ,The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.2.1 ,The only exception is in the Section 5, Apparatus, 5.1 where there is no relevant SI equivalent.

1.3 ,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.

1.4 ,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.


Significance and Use:

4.1 ,Both suppliers and users of pulverized ceramic powders will find this test method useful to determine particle size distributions for materials specifications, manufacturing control, development, and research.

4.2 ,The test method is simple, although tedious, uses inexpensive equipment, and will provide a continuous curve with data obtained with standardized woven sieves.
