Standard Test Method for Ethylene Diamine Tetraacetate (EDTA) in Soaps or Synthetic Detergents
N D1767
Annotation
This test method covers the determination of ethylene diamine tetraacetate (EDTA) in soaps and synthetic detergents. Throughout this test method EDTA represents the hydrated disodium salt containing 2 moles of H2O. In the chemical literature this is frequently abbreviated to Na2H2Y4· 2H2O.
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 тетраацетата этилендиамина (EDTA) в четверти кирпича или синтетических моющих средствах
Этот метод испытаний покрывает определение тетраацетата этилендиамина (EDTA) в четверти кирпича и синтетических моющих средствах. Всюду по этому методу испытаний EDTA представляет гидратируемую двунатриевую соль, содержащую 2 родинки H2O. В химической литературе это часто сокращается до Na2H2Y4 · 2H2O.
