Overview
This part of ISO 15171 specifies dimensions, performance requirements, and test procedures for diagnostic couplings with an M16 × 2 connection end that can be connected under pressure without tools to a maximum pressure of 40 MPa (400 bar) providing following stud ends: - ISO 6149-2 - M14 × 1,5; - ISO 9974-2 - M14 × 1,5; - ISO 1179-2 - G 1/4; - ISO 11926-2 - 7/16-20 UNF. The dimensions of the coupler counterpart are specified. The coupling is designed for use in hydraulic systems that use mineral oils. 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 working pressure depends upon the materials, design, working conditions, application etcetera. This standard includes the German version of ISO 15171-2: 2016, prepared by Technical Committee ISO/TC 131 "Fluid power systems", Subcommittee SC 4 "Connectors and similar products and components" and Working Group WG 4 "Quick-action couplings". The national interests during the preparation were represented by Committee NA 060-36-40-01 AK "Schnelltrennkupplungen" ("Quick-action couplings") at Technical Committee "Fluid power systems" of DIN Standards Committee Mechanical Engineering (NAM). Representatives of the manufacturers and users of pipes, hoses, connecting elements and quick-action couplings were involved in the preparation.
