Th
3、e work of preparing International Standards is normally carried out through IS0 technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-gov
4、ernmental, in liaison with ISO, also take part in the work. IS0 collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Draft International Standards adopted by the technical committees are circulated to the member bodies for
5、voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. International Standard IS0 10945 was prepared by Technical Committee lSO/TC 131, Nuid power systems. 0 IS0 1994 All rights reserved. Unless otherwise specified, no part of this pu

8、orts 1 Scope This International Standard specifies the types and the dimensions of the gas filling ports of gas-loaded ac- cumulators used in hydraulic fluid power systems. It describes two male ports for filling the gas side of a gas-loaded accumulator. These ports are designated by the following:
9、- male port with Ml 6 x 2 thread, in accordance with IS0 261 and IS0 724, which is preferred for new designs (see 4.1); - male port with 8Vl thread in accordance with IS0 4570-I (see 4.2).
