ISO 6149-4:2017 specifies dimensions and performance requirements for external hex and internal hex port plugs for use with ISO 6149-1 ports. Port plugs in accordance with this document can be used at working pressures up to 63 MPa (630 bar[1]). The permissible working pressure depends upon the plug end size, materials, design, working conditions, application, etc. Conformance to the dimensional information in this document does not guarantee rated performance. Each manufacturer is expected to perform testing according to the specification contained in this document to assure that components comply with the performance ratings. WARNING: The use of stud ends conforming to this document with ports conforming to the relevant parts of ISO 1179, ISO 9974 and ISO 11926 could lead to a hazardous situation.
[1] 1 bar = 0,1 MPa = 105 Pa; 1 MPa = 1 N/mm2.
