Standard Test Method for Sodium Alkylbenzene Sulfonate in Synthetic Detergents by Ultraviolet Absorption
N D1768
Annotation
This test method covers commercial synthetic detergents and built detergent formulations that do not contain organic additives such as amides. Optical dyes and materials normally found in formulated detergents do not interfere; however, materials other than sulfonates that possess strong ultraviolet absorptions must be absent. The indicated sample size and aliquoting scheme is based on samples containing 30 to 40% of active ingredient.
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. Material Safety Data Sheets are available for reagents and materials. Review them for hazards prior to usage.

Стандартный метод испытаний для сульфоната алкилбензола натрия в синтетических моющих средствах ультрафиолетовым поглощением
Этот метод тестирования покрывает коммерческие синтетические моющие средства и созданные моющие формулировки, которые не содержат органические дополнения, такие как амиды. Оптические красители и материалы, обычно найденные в сформулированных моющих средствах, не вмешиваются; однако, материалы кроме сульфонатов, которые обладают сильными ультрафиолетовыми поглощениями, должны отсутствовать. Обозначенная схема объема выборки и аликвотирования основана на образцах, содержащих 30 - 40% активного ингредиента.
