The work of preparing International Standards is normally carried out through iSO technical committees. Each member body interested in a subject for which a technical committee has been established has liaison with IsO, also take part in the work. IsO collaborates closely with the International Electrotechnical Commission(lEC)onallmattersofelectrotechnicalstandardization International Standards are drafted in accordance with the rules given in the ISO/lEC Directives, Part 3. Subcommittee SC 8, Product testing. IsO 10767 consists of the following parts, under the general title Hydraulic fluid power Determination of pressure ripple levels generated in systems and components: Part 1: Precision method for pumps Part2: Simplified methodforpumps Part 3: Method for motors Annexes A and B form a normative part of this part of iSO 10767.
