BS EN ISO 4759-3:2016规定了产品等级为A、C和F的带公称直径的平垫圈的公差 直径为1 mm至150 mm（含），设计用于与螺栓结合的螺栓接头， 螺钉、螺柱和螺母。ISO 4759的本部分适用于非平垫圈，但不包括所有公差 与这些垫圈有关。它适用于非固定垫圈和固定垫圈，以及标准垫圈和非标准垫圈。它不适用于动态碟形弹簧。产品等级F和A的垫圈拟与产品的螺栓、螺钉、螺柱和螺母一起使用 甲级和乙级；C级产品垫圈用于螺栓、螺钉、螺柱和螺母 产品等级C。注:产品等级指与尺寸和几何尺寸相关的特定公差范围 特性（精密公差为F级产品，精密公差为A级产品，精密公差为C级产品） 大公差）。附录A给出了取自ISO 286-1和ISO 286-2的公差。交叉引用:ISO 1101ISO 2692ISO 286-1ISO 286-2购买本文件时可获得的所有现行修订均包含在购买本文件中。

BS EN ISO 4759-3:2016 specifies tolerances for flat washers of product grades A, C and F with nominal diameters of 1 mm to 150 mm inclusive, designed to be used in bolted joints in combination with bolts, screws, studs and nuts.This part of ISO 4759 may be applied to non-flat washers however it does not include all the tolerances related to these washers.It applies to non-captive and captive washers, and to standard and non-standard washers.It does not apply to dynamic disc springs.Washers of product grades F and A are intended to be used with bolts, screws, studs and nuts of product grades A and B; washers of product grade C are intended to be used with bolts, screws, studs and nuts of product grade C.NOTE The product grade refers to a specific tolerance range related to dimensional and geometrical characteristics (product grade F for fine tolerances, product grade A for precise tolerances, product grade C for large tolerances).Annex A presents tolerances taken from ISO 286-1 and ISO 286-2.Cross References:ISO 1101ISO 2692ISO 286-1ISO 286-2All current amendments available at time of purchase are included with the purchase of this document.
