Prior to the introduction of the INSARAG External Classification System, USAR Teams completed a self-classification as a Light, Medium or Heavy USAR Team. This self-classification was then submitted to the INSARAG Secretariat and recorded in its Directory of International USAR Teams. INSARAG strongly recommends Member States to establish a NAP as an initial step.

在引入 IEC 体系前，USAR 队伍已完成轻型、中型、重型队伍自测，把自测结果提交秘书处并记录在国际 USAR 队伍目录中。INSARAG 强烈建议各成员国首先建立国家认证程序（NAP）。
