ISO 18589-2:2015规定了基于ISO 11074和ISO/IEC 17025的一般要求，用于抽样和样品测试准备的规划（台式研究和区域侦察）的所有步骤。它包括抽样策略的选择，抽样计划的纲要，一般抽样方法和设备的介绍，以及适用于测量土壤中放射性核素活动的样本的预处理方法。 ISO 18589-2:2015针对辐射防护目的，确定土壤中放射性的负责人。适用于园林，农田，城市，工业用地以及不受人类活动影响的土壤。 ISO 18589-2:2015适用于所有实验室，无论人员数量或测试范围如何。当实验室不承担ISO 18589本部分所涵盖的一项或多项活动（如规划，抽样或测试）时，相应的要求不适用

ISO 18589-2:2015 specifies the general requirements, based on ISO 11074 and ISO/IEC 17025, for all steps in the planning (desk study and area reconnaissance) of the sampling and the preparation of samples for testing. It includes the selection of the sampling strategy, the outline of the sampling plan, the presentation of general sampling methods and equipment, as well as the methodology of the pre-treatment of samples adapted to the measurements of the activity of radionuclides in soil. ISO 18589-2:2015 is addressed to the people responsible for determining the radioactivity present in soil for the purpose of radiation protection. It is applicable to soil from gardens, farmland, urban, or industrial sites, as well as soil not affected by human activities. ISO 18589-2:2015 is applicable to all laboratories regardless of the number of personnel or the range of the testing performed. When a laboratory does not undertake one or more of the activities covered by this part of ISO 18589, such as planning, sampling, or testing, the corresponding requirements do not apply.
