1 适用范围在ISO6621—5中,对通常图纸上不标注的质量特征下了定义,并作了部分规定.本标准适用于1 铸铁、碳化物铸铁,可锻铸铁或球墨铸铁整体环;2 由铸铁环和撑簧组成的组合环;3 钢制组合环和钢制整体环,即成型钢制油环或钢带组合油环;为补充ISO6621—2中规定的有关质量特征检测的接受极限,ISO6621—5适用于无定量检测方法和无需放大,仅用正常视力的肉眼(如有视觉缺陷,可用眼镜校至正常视力)进行的质量特征检验.这些特征(表面缺陷)是对环高、径向厚度和闭口间隙标准公差的补充.ISO6621—5中,未规定可接受的质量极限标准(AQL).最好由供需双方商定适当的标准.对此,应遵循ISO2859中所含的推荐标准.
1 Scope This standard applies to 1 cast iron, carbide cast iron, malleable iron or ductile iron integral ring; 2 cast iron ring And spur spring; 3 steel combination ring and steel integral ring, that is, forming steel oil ring or steel band combination oil ring; to complement ISO6621-2 in the acceptance of the quality characteristics of the detection limit, ISO6621- 5 is applicable to the quantitative test method and the quality inspection of the naked eye without normal magnification and normal vision only (if visual defects can be calibrated with glasses to normal visual acuity) .These features (surface defects) are the characteristics of ring height, radial thickness And the standard clearance of the closing clearance Supplementary ISO 1661-5 does not specify an acceptable quality limit standard (AQL) It is best to be agreed upon by both supply and demand the appropriate standard, which should follow the recommended standards contained in ISO2859.
