ISO/TS 18409:2018 is a specific application of ISO 18413:2015, specifically Annexes A and B.

The scope of ISO/TS 18409:2018 does not include providing efficient and effective cleaning methods for hose assemblies. These methods are recommended for statistical validation of other hose cleaning methods, which are more suitable for systematic processing of large production batches.

Contamination analysis is excluded from the scope of this document.

The designation and nomenclature established in this document are applicable for procurement purposes when agreed to by user and supplier.

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.

NOTE The Introduction of this document gives recommendations for ports and stud ends to be used for new designs in hydraulic fluid power applications.

[1] 1 bar = 0,1 MPa = 105 Pa; 1 MPa = 1 N/mm2.

Port plugs in accordance with ISO 9974-4:2006 can be used at working pressures up to 63 MPa (630 bar). The permissible working pressure depends upon the plug end size, materials, design, working conditions, application, etc.
