ISO 6360-4:2004规定了牙科用旋转金刚石仪器和金刚石涂层圆盘的特定特性代码。这三位数字构成15位整数中第四组三位数字，其原理在ISO 6360-1和ISO 6360-2中进行了解释。 ISO 6360-4:2004还提供了一个三位数的数字，除了15位数的代码外，制造商还可以根据自己的判断，使用该数字为金刚石仪器和金刚石涂层盘提供额外的信息。 注:除了三种官方ISO语言（英语、法语和俄语）中使用的旋转仪器和附件的术语外，ISO 6360-4:2004还提供了德语中的等效术语；这些文件由德国成员机构（DIN）负责发布。 然而，只有官方语言中给出的术语才可视为ISO术语。

ISO 6360-4:2004 specifies the code numbers for specific characteristics of rotary diamond instruments and diamond-coated discs for use in dentistry. This three-digit number forms the fourth group of three digits in the 15-digit overall number, the principles of which are explained in ISO 6360-1 and ISO 6360-2. ISO 6360-4:2004 also gives a three-digit number which in addition to the 15-digit code number may be used to provide additional information for diamond instruments and diamond-coated discs, at the discretion of the manufacturer. NOTE In addition to terms for rotary instruments and accessories used in two of the three official ISO languages (English, French and Russian), ISO 6360-4:2004 gives the equivalent terms in the German language; these are published under the responsibility of the member body for Germany (DIN). However, only the terms given in the official languages can be considered as ISO terms.
