Pressures for connectors should be marked in ISO 2944. ISO/TC 131/SC 4 will recommend to ISO/TC 131 that ISO 2944:2000 be revised with updated pressures after the new ISO 4399 is published.

ISO 2944, Fluid power systems and components Nominal pressures. ISO 5598, Fluid power systems and components Vocabulary. To write: a pressure value assigned to a component, piping or a system for the purpose of convenient designation and indicating its belonging to a series. To write: Note 1 to entry: This definition is the same as that used in ISO 2944 and is intended solely to complete this document. A more comprehensive definition for general purposes may be established subsequently. To write: with the equivalent value in bars in the following column Accepted in principle. Paragraph to be changed to: When used in a sentence, the nominal pressure shall be expressed in megapascals (MPa), with the equivalent value in bar 1 shown in parentheses. DE-04 005 5 Table 1 te In pneumatics pressures below 10 bar are generally in use. Quite often 6,3 bar is used for testing pneumatic components. To define reasonable pressure steps, we propose in addition the pressures 1 bar and 2,5 bar. To add 0,1 MPa / 1 bar 0,25 MPa / 2,5 bar 0,63 MPa / 6,3 bar Not accepted. The proposed pressures may be used in pneumatic applications, however there are no connectors rated for lower that 1 MPa (10 bar). 1 MB = Member body / NC = National Committee (enter the ISO 3166 two-letter country code, e.g. CN for China; comments from the ISO/CS editing unit are identified by **) 2 Type of comment: ge = general te = technical ed = editorial Page 1 of 2

Alternatively, it can be written in square brackets, but it should identical with 6,3 MPa which is used in the same standards. To add 5 MPa / 50 bar DE-06 007 5 Table 1 te For discussion: The pressure value 8 MPa / 80 bar is used in ISO 8434-6 for 2 inch connectors. To add 8 MPa / 80 bar Accepted, but in square brackets. DE-07 008 5 Table 1 te Although the pressure values 20 MPa and 40 MPa are actually used in many component standards they will be replaced by 21 MPa (3000 PSI) and 42 MPa (6000 PSI) in future. Therefore, they should be written within square brackets so that these pressures will not be used for new designs. To write [20 MPa] / [200 bar] and [40 MPa] / [400 bar]. DE-08 009 5 Table 1 te The pressure gap between 42 MPa and 56 MPa is very huge. 50 MPa will close this gap and is more used than 49 MPa for hydraulic hoses, pumps and 8434-1 light duty connectors in small sizes. To add 50 MPa / 500 bar DE-09 010 5 Table 1 te For discussion: 70 MPa is used in ISO 16301, Rubber and plastics hoses and hose assemblies, wire- or textile-reinforced, for manually operated hydraulic jacks Specification, and For discussion 70 MPa (700 bar) to be listed. ISO 19385, Rubber and plastics hoses and hose assemblies, wire- or textile-reinforced, for water jetting or water blasting applications - Specification (will be replaced by ISO/NP 23384 for water jetting and hydraulic applications) To add in square brackets? DE-10 011 5 Table 1 te For discussion: 80 MPa is used for 8434-1 heavy duty connectors in small sizes.
