Testing of plastics Determination of water absorption
N 53495
Annotation
Scope and field of application
This standard describes the conventional methods of determining water absorption using the change in mass of plastic (except cellular materials 1)) specimens after conditioning in water or water vapour .
The absorption of water can influence various properties of a plastic or a plastics component. In conjunction with other observations, the types of water absorption determined as specified in this standard can give an indication of the behaviour of plastics when influenced by liquid or gaseous water.
1) See DIN 7726 for the definition of "cellular material".

Испытание Определения пластмассы водного поглощения
Объем и область применения
Этот стандарт описывает обычные методы определения водного поглощения с помощью изменения в массе пластмассы (кроме сотовых материалов 1)), экземпляры после создания условий в водяном или водяном паре.
Поглощение воды может влиять на различные свойства пластмассы или компонента пластмассы. В сочетании с другими наблюдениями типы водного поглощения, определенного, как определено в этом стандарте, могут дать индикацию относительно поведения пластмассы когда под влиянием жидкой или газовой воды.
