1.1 本指南涵盖岩芯取样术语、不同类型岩芯取样器的优缺点、取样过程中可能发生的岩芯变形、检测和最小化岩芯变形的技术以及解剖和保存沉积物岩芯的方法。 1.2 在本指南中，采样程序和设备根据水深分为以下几类:深度小于0.5 m的采样、深度在0.5 m到10 m之间的采样和深度超过10 m的采样。每一类分为两个部分:收集短芯的设备和收集长芯的设备。 1.3 本指南强调一般原则。只有在少数情况下才会给出分步说明。由于岩芯采样是基于现场的操作，因此通常必须修改方法和设备以适应当地条件。此修改过程需要两个基本要素:操作员技能和判断。两者都不能被书面规则所取代。 1.4 包括取样器图纸，以显示尺寸和比例。这些采样器主要作为设备的示例（或通用表示）提供，这些设备可以从商业上购买或根据技术期刊上的计划制造。 1. 5. 本指南是已发表科学文章和工程报告的简要总结。本指南中列出了这些参考文献。这些文件提供了本指南中未给出的操作细节，但对成功规划和完成岩芯取样项目至关重要。 1.6 以国际单位制表示的数值应视为标准值。本标准不包括其他计量单位。 1.7 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 有关特定警告声明，请参阅 6.3 和 11.5 . 1.8 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。

1.1 This guide covers core-sampling terminology, advantages and disadvantages of different types of core samplers, core-distortions that may occur during sampling, techniques for detecting and minimizing core distortions, and methods for dissecting and preserving sediment cores. 1.2 In this guide, sampling procedures and equipment are divided into the following categories based on water depth: sampling in depths shallower than 0.5 m, sampling in depths between 0.5 m and 10 m, and sampling in depths exceeding 10 m. Each category is divided into two sections: equipment for collecting short cores and equipment for collecting long cores. 1.3 This guide emphasizes general principles. Only in a few instances are step-by-step instructions given. Because core sampling is a field-based operation, methods and equipment must usually be modified to suit local conditions. This modification process requires two essential ingredients: operator skill and judgment. Neither can be replaced by written rules. 1.4 Drawings of samplers are included to show sizes and proportions. These samplers are offered primarily as examples (or generic representations) of equipment that can be purchased commercially or built from plans in technical journals. 1.5 This guide is a brief summary of published scientific articles and engineering reports. These references are listed in this guide. These documents provide operational details that are not given in this guide but are nevertheless essential to the successful planning and completion of core sampling projects. 1.6 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.7 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. For specific warning statements, see 6.3 and 11.5 . 1.8 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
