Standard Test Method for Specific Surface Area of Alumina or Quartz by Nitrogen Adsorption
 N C1069

Annotation

This test method covers the determination of the specific surface area of aluminas and silicas used in the manufacture of ceramics. The test method is a general one, permitting the use of any modern commercial nitrogen adsorption apparatus but strictly defining the outgassing procedure. Calculations are based on the Brunauer-Emmett-Teller (BET) equation.

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

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.

Метод стандартной пробы для области удельной поверхности глинозема или кварца адсорбцией азота

Этот метод испытаний покрывает определение области удельной поверхности aluminas и кварцев, используемых в изготовлении керамики. Метод испытаний является общим, разрешая использование любого современного коммерческого адсорбционного аппарата азота, но строго определяя outgassing процедуру. Вычисления основываются на уравнении Brunauer-Emmett-Teller (BET).
