ISO 16138:2006规定了由热塑性材料制成的隔膜阀的设计、功能特性和制造要求，该隔膜阀用于隔离和控制服务，其与管道系统的连接，阀体材料及其压力/温度额定值在-40摄氏度和+120摄氏度之间，使用寿命为25年，并详细说明了他们的测试。 ISO 16138:2006适用于安装在工业管道系统中的手动或电动阀门，无论其应用领域和输送的流体如何。 它涉及DN 8、DN 10、DN 15、DN 20、DN 25、DN 32、DN 40、DN 50、DN 65、DN 80、DN 100、DN 125、DN 150、DN 200和DN 250的范围，以及PN 6、PN 10、PN 16和150级的范围。

ISO 16138:2006 specifies requirements for the design, functional characteristics and manufacture of diaphragm valves made of thermoplastics materials intended for isolating and control service, their connection to the pipe system, the body materials and their pressure/temperature rating between -40 degrees Celsius and +120 degrees Celsius, for a lifetime of 25 years, and also specifies their tests. ISO 16138:2006 is applicable to hand- or power-operated valves to be installed in industrial pipe systems, irrespective of the field of application and the fluids to be conveyed. It is concerned with the range of DN 8, DN 10, DN 15, DN 20, DN 25, DN 32, DN 40, DN 50, DN 65, DN 80, DN 100, DN 125, DN 150, DN 200 and DN 250, and the range of PN 6, PN 10, PN 16 and Class 150.
