Название (рус.): | Пластмассы. Определение изменений под воздействием плесени и бактерий. Визуальная оценка или измерение изменения массы и физических свойств |
Название (англ.): | Plastics; Determination of behaviour under the action of fungi and bacteria; Evaluation by visual examination or measurement of change in mass or physical properties |
Описание (англ.): | The determination consists in exposing test specimens of plastics to the action of fungi or bacteria for specified periods of time and in specified conditions of temperature and humidity. The test for resistance to fungi can be carried out by two methods. In method A the plastic specimen is exposed to spores of specified fungi which are only supplied with incomplete nutritivemedium (test for growth), and in method B the specimen is exposed to spores of specified fungi which are distributed on an complete nutritive medium (test for fungstatic effect). |
