根据国家标准总局的指示,全国液压与气动标准化技术委员会决定参照国际标准(ISO),起草我国液压气动用橡胶密封件的国家标准。这对促进密封件标准化、专业化生产,开拓国际市场都是有利的。现用橡胶O形密封圈标准GB1235-76(试行)将逐步向ISO3601/I～Ⅳ一组标准过渡。关于O形圈的尺寸系列和沟槽尺寸设计(ISO3601/Ⅰ和ISO3601/Ⅱ),可望在年内完成起草工作上报。Y形及其他往复运动用密封圈,将以ISO5597/Ⅰ为基础拟订其中KY形密封圈尺寸
According to the instructions of the State Administration of Standards, the National Hydraulic and Pneumatic Standardization Technical Committee decided to draft the national standards for rubber seals for hydraulic and pneumatic applications in China with reference to International Standards (ISO). This is to promote the standardization of seals, specialized production, open up the international market are beneficial. The existing rubber O-ring standard GB1235-76 (Trial) will gradually shift to a standard set of ISO3601 / I ~ Ⅳ. O-ring on the size of the series and groove size design (ISO3601 / Ⅰ and ISO3601 / Ⅱ), is expected to be completed within the year drafting report. Y-shaped and other reciprocating seals, will be based on ISO5597 / Ⅰ Formulation which KY ring size
