ISO 18400-105:2017确立了土壤和相关材料样品的包装、保存、运输和交付的一般原则，强调了需要对样品进行化学分析时的要求，但其目的是，当需要其他形式的测试（例如生物测试、扰动或未扰动样品的物理测试）时，应酌情调整一般程序。ISO 18400的其他部分给出了特定取样目的的特殊程序（另见7.2）。 ISO 18400-105:2017旨在与ISO 18512一起阅读。

ISO 18400-105:2017 establishes general principles for packing, preservation, transport and delivery of samples of soil and related materials with an emphasis on requirements for when chemical analysis of the samples is required, but with the intention that the general procedures are to be adapted as appropriate when other forms of testing are required (e.g. biological testing, physical tests on disturbed or undisturbed samples). Special procedures for specific sampling purposes are given in other parts of ISO 18400 (see also 7.2). ISO 18400-105:2017 is intended to be read in conjunction with ISO 18512.
