Standard Test Method for Silicon in Engine Coolant Concentrates by Atomic Absorption Spectroscopy
 N D6129

Annotation

This test method covers the determination of silicon in the range from 200 to 500 ppm in engine coolant concentrates by atomic absorption. This method is as accurate and precise as photometric methods, while requiring considerably less operator time and avoiding problems with reagent instability.

Coolants with silicon content outside of this range may be analyzed by this method by suitably adjusting the sample size. Care should be taken to ensure that the glycol content of the working standards corresponds to that of the sample solution being analyzed.

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 кремния в концентратах охлаждающей жидкости двигателя атомно-абсорбционной спектроскопией

Этот метод испытаний покрывает определение кремния в диапазоне от 200 до 500 частей на миллион в концентратах охлаждающей жидкости двигателя атомным поглощением. Этот метод так же точен и точен как светоизмерительные методы при требовании значительно меньшего количества времени оператора и предотвращении проблем с нестабильностью реактива.
