①, a. 在螺栓和平垫圈组合件中,只有 200HV 和 300HV 性能等级被标准化,应符合 ISO 10644 或 ISO 10673。
②, b. 380HV 性能等级不包括在现行 ISO 产品标准中,如需要,该性能等级平垫圈的使用应由供需协议;
③, c. 380HV 性能等级平垫圈的螺栓连接设计应防止平垫圈中的弯曲效应和拉伸应力,尤其是对于开槽和扩孔的平垫圈;
④, d. RC表示最优组合,如果连接设计和/或安装条件经过验证,也可以使用标有脚注d的组合;
⑤, e. 可用于螺栓连接;
⑥, f. 不应使用。
⑦, 对于螺纹自成形螺钉和与软材料(如塑料、木材等)连接螺钉,应根据其预期用途确定与平垫圈性能等级的组合。

①, 在满足机械和物理性能要求的前提下,材料的选择应由制造商自行决定。
②, NA――不适用
③, a. 有争议时,实施成品分析。
b. 对于组合件用平垫圈,见 ISO 10644 或 ISO 10673。化学成分和最低回火温度应由供需协议。
c. 对于特殊应用平垫圈(如热浸镀锌平垫圈),化学成分和最低回火温度应由供需协议。
④, d. 硼的最高含量为0.003%,但如果非有效硼是由添加钛和/或铝控制的,则可高达0.005%。
e. 性能等级200HV平垫圈可采用具有适当机械性能的原材料制造,也可在制造后对平垫圈进行淬火并回火。在满足机械和物理性能的情况下,工艺流程选择由制造商确定。
⑤, f. 对这些性能等级用材料,应有足够的淬透性,以确保平垫圈芯部在“淬硬”状态、回火前获得大约90%的马氏体组织。
g. 碳钢可以包含有铬、锰、镍等合金。
⑥, h. 这些合金钢至少应含有下列一种元素,其最低含量为:铬0.30%、锰0.20%、镍0.30%、钒0.10%、钼0.08%和硼0.0008%。当元素以组合形式出现时,合金元素含量不能少于单个合金元素含量总和的70%。
⑦, i. 有关氢脆的考虑,请参阅 ISO/TR 20491。
