National Annex NA (informative) Bibliography DIN 51519, ISO viscosity classification of industrial liquid lubricants DIN ISO 16030:2007-05 4 Pneumatic fluid power Connections Ports and stud ends Introduction In pneumatic fluid power systems, power is transmitted and controlled through a

13、ir under pressure within a circuit. Components are connected through their threaded ports by means of connectors to tubes and pipes or to hose fittings and hoses. Ports are an integral part of fluid power components, such as valves, cylinders and filters. In the past, various thread and port systems

14、 (for example ISO 7-1 and ISO 1179:1981) have been used in pneumatic fluid power systems. See the scope of this International Standard for further information on the relationship between those standards and this International Standard. Where ISO 7-1 tapered external threads are intended to connect t

15、o pneumatic components with internal threads, the ports in those components should conform to ISO 1179:1981. DIN ISO 16030:2007-05 51 Scope This International Standard specifies dimensions and performance requirements for ports and stud ends with parallel threads for pneumatic fluid power applicatio

16、ns. It specifies reusable, positively retained seals for leak-free connections, for use at pressures from 0,09 MPa ( 0,9 bar 1) up to 1,6 MPa (16 bar). Only this International Standard is applicable for threaded ports and stud ends specified in new designs in pneumatic fluid power applications. Port

17、s and stud ends conforming to this International Standard are not intended to connect with ports and stud ends that conform to ISO 1179 or threads that conform to ISO 7-1. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute pr

18、ovisions of this International Standard. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent editions of

19、the normative documents indicated below. For undated references, the latest edition of the normative document referred to applies.

26、ods 6.1 General 6.1.1 Basic principles The tests in clause 6 are type tests to qualify port and stud end design and materials.
