Standard Test Method for Rubber Latex-Styrene-Butadiene Copolymer - Determination of Residual Styrene
 N D4026

Annotation

This test method covers the determination of the residual styrene content of styrene butadiene (SBR) latex. This test method is based upon direct injection of a diluted latex into a gas chromatograph. The amount of residual styrene is calculated using an internal standard technique.

The range of residual styrene covered is approximately 100 to 3000 mg/kg (ppm) with a lower detection limit of approximately 50 mg/kg (ppm).

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 сополимера бутадиена стирола каучукового латекса - определение остаточного стирола

Этот метод испытаний покрывает определение остаточного содержания стирола бутадиена стирола (SBR) латекс. Этот метод испытаний основан на непосредственном впрыске разбавленного латекса в газовый хроматограф. Сумма остаточного стирола вычисляется с помощью внутреннего стандартного метода.
