DS/ISO 6020-1:1989 液压传动.单杆液压缸.装配尺寸?160巴(16000kPa)系列.第1部分:中型系列

This International Standard establishes metric mounting dimensions for medium series cylinders as required for interchangeability of commonly used hydraulic cylinders. The medium series dimensions are applicable to both round or square head cylinders thus allowing a wider range of applications. They permit larger ports with longer cushions that are particularly suitable for applications requiring higher velocity and rapid decelerations. NOTE — This International Standard allows manufacturers of hydraulic equipment freedom in the design of metric cylinders and does not restrict technical development but provides basic guidelines.

DS/ISO 6072:1989 液压传动.弹性材料和流体之间的适应性

This International Standard provides formulations, mixing and vulcanization procedures for three types of elastomeric compositions: a) acrylonitrile-butadiene rubber (NBR 1); b) fluoroelastomers (FPM 1); c) ethylene propylene diene rubber (EPDM 1). These procedures evaluate the effect of mineral-based and fireresistant hydraulic fluids upon such compositions by measure-ment, under controlled conditions, of physical properties of standard test pieces of the suitable test elastomer before and after immersion in the fluids. The elastomeric materials used in these formulations are sensitive to fluid variations and have comparatively high swelling characteristics. Stable cure systems should be used to give adeqnate storage life. NOTE — This International Standard does not provide formulations of elastomeric materials for actual service. The changes in volume, hardness, tensile strength and elongation at break [which standard test specimens of the suitable standard test elastomer undergo when immersed in a certain fluid under specified test conditions (see table 7)] establish an elastomer compatibility index (ECI) for this fluid, which can be expressed in the format given in clause 5. The ECI (which should be quoted by oil suppliers) allows selec-tion of suitable combinations of fluids and elastomeric materials without prolonged testing. In the case of mineral-based oils, it will be possible to predict the percentage volume change of commercial rubbers (see annex A). NOTE — The ECI may provide enough information so as to eliminate totally unsuitable elastomer/fluid combinations without having to resort to extensive screening tests. Representative standard compositions of various types of elastomers permit evaluation of the effect of hydraulic fluids on such compositions and comparison with commercial elastomeric materials for actual service. They would also assist producers of additives and hydraulic fluids in the development of hydraulic fluids compatible with different elastomer types.

DS/ISO 6099:1989 液压系统和组件.液压缸.装配尺寸和装配类型的识别标志

This International Standard specifies a conventional system for identifying fluid power cylinder dimensions and mounting dimensions thereof. Such a system will be composed of a) a letter code for identifying — mounting dimensions — envelope dimensions — cylinder fitting dimensions; b) a code for identifying cylinder mounting types. This International Standard does not represent a standard list of all cylinder mounting types. The codes indicated in this International Standard are also not to be considered as complete for the development of future interchangeability standards. It establishes uniform descriptions for dimensions and achieves a conformity of language. Although this International Standard presents a code and a method of dimensioning, it is not intended that all dimensions shall be standardized. The same codes can be used for analogous dimensions when this involves neither confusion nor misunderstanding.
