ISO 8843:2005建立了识别电气连接器压接可拆卸触点的系统。本国际标准中规定的系统包括压接筒外径周围的两个色带，对于热电偶或高温触点，还包括附加字母或一个色点；然而，该系统并不排除使用进一步的方法来确定额外的参数，例如电缆尺寸和材料。 如有规定，此触点识别系统适用于ISO标准触点。建议首选和非首选触点使用该系统- 首选类型。在首选类型的触点中，触点活动部分和触点筒接受的线规具有相同的尺寸。在非首选类型的触点中，触点活动部分的尺寸不同于压接筒可接受的线规。

ISO 8843:2005 establishes a system for identifying crimp-removable contacts for electrical connectors. The system specified in this International Standard consists of two colour bands around the external diameter of the crimp barrel and, for thermocouple or high-temperature contacts, of additional letters or of a colour point; the system, however, does not preclude further means being used to identify additional parameters, such as cable size and material. This contact identification system applies, when specified, to ISO standard contacts. The use of the system is recommended for contacts of both the preferred and non-preferred types. In contacts of the preferred type, the contact active portion and the wire gauge accepted by the contact barrel have the same size. In contacts of the non-preferred type, the size of the active portion of the contact differs from the wire gauge accepted by the crimp barrel.
