Status: Effective - Supersedes. The limitation of effectiveness has been lifted: Decree of the State Standard No. 2184 dated 06/28/89; IUS 11-1989

The standard applies to chemical products and reagents and establishes the following methods for determining water: a) with Fisher's reagent for the mass of water in the sample of the analyzed preparation of 0.0005-0.05 g; b) drying for the mass of water in the sample of the analyzed drug is not less than 0.001 g; c) distillation with an organic solvent (Dean and Stark method) for the mass of water in the sample of the analyzed preparation 0.3-8.0 g.

Стандарт распространяется на химические продукты и реактивы и устанавливает следующие методы опреедления воды: а) с реактивом Фишера для массы воды в навеске анализируемого препарата 0,0005-0.05 г; б) высушивание для массы воды в навеске анализируемого препарата не менее 0,001 г; в) отгонка с органическим растворителем (метод Дина и Старка) для массы воды в навеске анализируемого препарата 0,3-8,0 г.
