| 发明名称 | Method for testing the tightness of water conducting components in a housing | ||
| 摘要 | The invention relates to the use of an indicator for testing the tightness of water conducting components in a housing which is either mixed into the water or released upon contacting water drops or generated from a generative material upon contact with water. According to the invention, the presence of the indicator in gaseous or vaporous form is detected by a sensor. | ||

| 主权项 | 1. A method of testing the tightness of water conducting components in a housing, said method comprising the steps of: introducing a generator substance, which upon contact with water produces a gaseous or vaporous indicator; positioning the generator substance in the housing below the components under test; and detecting the occurrence of the indicator using a sensor sensitive to the indicator wherein the generator substance used is a mixture of sodium and acid, which produces CO2 as the gaseous or vaporous indicator upon contact with water. | ||
