The work of preparing International Standards
10、is normally carried out through ISO 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 organisations, governmental and non-governmental, in liaison with ISO, also take pa
11、rt in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardisation. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. Draft International Standards adopted by the
12、 technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.

13、946:1999 BSI 02-2000 1 Introduction In hydraulic fluid power systems, power is transmitted and controlled through a liquid under pressure within an enclosed circuit. Gas-loaded accumulators are components that are able to store and to return energy in accordance with the principle of the compressibi
14、lity of gases. Hydraulic fluid enters and leaves these accumulators through ports. 1 Scope This International Standard specifies the types and selection of hydraulic ports of gas-loaded accumulators with separator, which are used in hydraulic fluid power systems. 2 Normative references The following
15、 normative documents contain certain provisions which, through reference in this text, constitute provisions of this International Standard. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to agreements based on this Internati
16、onal Standard are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below.
