DEFINITIONS For the purpose of this document, the definit

17、ions given in ISO 5598 and the following definition apply. 3.1 QUICK ACTION The joining of two components in a fashion with only hands and without wrenches and other mechanical means. 4. REQUIREMENTS 4.1 Size and Type of Port 4.1.1 Temperature, Pressure, and Sampling The port size for measuring temp

18、erature, pressure, and for obtaining fluid samples shall be M14x1.5 per ISO 6149-2 or shall be 9/16-18 UNF-2B per SAE J1926-2 (ISO 11926-2). 4.1.2 Flow Measurement Flow measurement ports shall be adequate for the flow to be measured. Sizes below 25.4 mm tube shall be ISO 6149-2 or SAE J1926-2 (ISO 1

19、1926-2), and size 25.4 mm and above shall be to SAE J518 (ISO 6162), four bolt flange. 5. APPLICATION GUIDELINES 5.1 Number of Diagnostic Points The number of diagnostic checking points will be determined by the manufacturer and should be commensurate with the complexity of the system being checked

20、and the economics required. 5.2 Location At least one diagnostic port should be located at the main system relief valve. However, consideration should be given to the following locations: pump inlet and outlet, valve inlet and outlet, valve work ports, filter inlet and outlet, actuator inletand outl

21、et, cooler inlet and outlet, and in each circuit with a relief valve. The preferred port location is in the component; however, it must be readily and safely accessible which might often require it to be located in a line. The ports should be located in the fluid stream to minimize any condition whi

22、ch might influence inaccuracies in readings. Diagnostic ports intended for the removal of representative fluid samples should be located in a turbulent flow section of the system and conform to ISO 4021. 5.3 Accessibility 5.3.1 Test ports should be accessible with common tools without the removal of

23、 any component other than sealing caps and access panels or plates. 5.3.2 A free access area of a minimum radius of 75 mm around centerline of port and 200 mm from port surface should be provided.
