This part of ISO 15171 specifies dimensions, performance requirements and test procedures for a diagnostic cou-pling with an M14 × 1,5 straight stud end to mate with an ISO 6149-1 port and an M16 × 2 connection end that can be connected under pressure without tools to a maximum pressure of 40 MPa [400 bar]. The dimensions of the coupling counterpart are specified. The coupling is designed for use in hydraulic systems that use mineral oil.
NOTE The use of this coupling with fluids other than mineral oil requires an agreement between the supplier and the purchaser.
Couplings in accordance with this part of ISO 15171 may be used at a maximum working pressure of 63 MPa (630 bar). The permissible working pressure depends upon the materials, design, working conditions, application, etc.
Conformance to the dimensional information in this part of ISO 15171 does not guarantee rated performance. Each manufacturer should perform testing according to the specification contained in this part of ISO 15171 to assure that components comply with the performance rating.
note:1) 1 bar = 0,1 MPa = 10 Pa; 1 Pa = 1 N/m
