1.1 本规程涵盖了通过目视评估压缩时排出的水的颜色来目视确定泥炭和其他高有机土壤的腐殖化程度。本规程不用于测定矿物土壤中有机物的有机分解程度。 1.2 此实践提供了一套用于执行一个或多个特定操作的说明。本文件不能取代教育或经验，应与专业判断结合使用。并非本惯例的所有方面都适用于所有情况。本ASTM标准并不代表或取代必须判断给定专业服务是否充分的护理标准，也不应在不考虑项目许多独特方面的情况下应用本文件。 本文件标题中的“标准”一词仅表示该文件已通过ASTM共识程序获得批准。 1.3 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者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。 1.4 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。 ====意义和用途====== 4.1 本规程的目的是使泥炭和其他有机土壤的常规描述标准化，用于各种用途（如泥炭地清单和资源评估）。该做法应用于补充其他现场信息，如场地位置、表面形态、表面植被、地下水位、含水量、纤维含量、木材含量以及可视觉识别的植物类型和部位。 注1: 本标准是一种视觉/手动方法，并不意味着要取代更精确的泥炭实验室分类方法（见分类 第4427页 ). 还应注意的是，这种做法独立于确定矿物矿床是否含有分类中定义的泥炭 第4427页 在实验室测定灰分的基础上（见试验方法 1974年2月 ).

1.1 This practice covers the visual determination of the degree of humification of peat and other highly organic soils by visually evaluating the color of the water expelled upon compression. This practice is not used for the determination of the degree of organic decomposition of organic matter in mineral soils. 1.2 This practice offers a set of instructions for performing one or more specific operations. This document cannot replace education or experience and should be used in conjunction with professional judgment. Not all aspects of this practice may be applicable in all circumstances. This ASTM standard is not intended to represent or replace the standard of care by which the adequacy of a given professional service must be judged, nor should this document be applied without consideration of a project’s many unique aspects. The word “Standard” in the title of this document means only that the document has been approved though the ASTM consensus process. 1.3 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. 1.4 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. ====== Significance And Use ====== 4.1 The purpose of this practice is to standardize the routine description of peat and other organic soils for various uses (such as, peatland inventories and resource evaluations). This practice should be used to supplement other field information, such as, site location, surface morphology, surface vegetation, water table, moisture content, fiber content, wood content, and visually identifiable plant types and parts. Note 1: This standard is a visual/manual method and is not meant to replace the more precise method of laboratory classification of peat (see Classification D4427 ). It should also be noted, this practice is independent of the determination of whether an articluar deposit contains peat that is defined in Classification D4427 on the basis of laboratory determination of ash content (see Test Method D2974 ).
