1.1 本规程涵盖了适用于将回转窑生产的多孔陶瓷材料指定为矿物改良剂的材料特性、物理要求和取样。多孔陶瓷材料可以用来代替表层土的含砂量，也可以混合到现有的表层土中。当与表层土混合或添加到表层土中时，通常使用5-20质量%的多孔陶瓷。 1.2 表层土改良的潜力/成功是通过其提供或增强未改良表层土中可能缺乏的表层土的某些或全部所需特性/特性的能力来衡量/确定的。 1.3 土壤通常由三种成分组成:水、空气和固体。固体可进一步分为两个子组分:有机物，如泥炭、淤泥或其他腐烂物质，以及无机矿物，如粘土、淤泥和沙子。多孔陶瓷属于无机矿物质亚组分，通常用于园艺表层土应用，作为土壤中沙子组分的替代品/替代品或添加剂。参见规范 D5268 ，表1。 1.4 单位-- 以国际单位制表示的数值应视为标准。括号中给出的值仅供参考，不被视为标准值。 以SI以外的单位报告试验结果不应被视为不符合本标准。 1.5 所有观测值和计算值应符合实践中制定的有效数字和四舍五入指南 D6026 ，除非被本试验方法取代。 1.5.1 用于规定如何在标准中收集/记录和计算数据的程序被视为行业标准。此外，它们代表了通常应保留的有效数字。所使用的程序不考虑材料变化、获取数据的目的、特殊目的研究或用户目标的任何考虑因素； 并且通常的做法是增加或减少报告数据的有效位数以与这些考虑相称。考虑工程数据分析方法中使用的有效数字超出了这些测试方法的范围。 1.6 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。并非此做法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共识程序批准。 1.7 本标准并不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。 1.8 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====== 5.1 景观美化和建筑专业人员以及高尔夫球场设计师是本标准的典型用户之一。当对土壤进行物理评估时，相对于其支持植物生长的适宜性（主要是草），必须进行测试以确定固体物质兼容性的存在和数量，然后用于确定潜在的空隙率、持水能力和有害物质。回转窑生产的多孔陶瓷材料是一种矿物改良剂，可以添加到表层土中，以增加其支持植物生长的适宜性。 5.2 规范中给出了适用表土的土壤含量的典型一般范围 D5268 然而，应当认识到，在某些地理区域，很难与参考表中的值一致。在这种情况下，需要制定当地可接受的规范。 注1: 本标准产生的结果的质量取决于执行该标准的人员的能力以及所用设备和设施的适用性。符合实践标准的机构 D3740 通常被认为能够胜任和客观的测试/取样/检查。 可靠的结果取决于许多因素；实践 D3740 提供了一种评估某些但不是所有这些因素的方法。

1.1 This practice covers the material characteristics, physical requirements, and sampling appropriate for the designation of the rotary kiln produced porous ceramic material as a mineral amendment. The porous ceramic material can be used to replace the sand content of a topsoil or it can be blended into an existing topsoil. Typically 5-20 % by mass of porous ceramics are used when blending with or adding to a topsoil. 1.2 The potential/success of a topsoil amendment is measured/determined by its ability to provide or enhance some or all of the desired properties/characteristics of the topsoil that may be deficient in the unamended topsoil. 1.3 Soils typically consist of three components: water, air and solids. Solids can be further divided into two sub-components: organic matter, such as peat, muck or other decayed matter, and inorganic mineral matter, such as clay, silt and sand. Porous ceramic falls into the inorganic mineral matter sub-component and is generally used in horticultural topsoil applications as a substitute/alternative or addition for the sand component of soil. See Specification D5268 , Table 1. 1.4 Units— The values stated in SI units are to be regarded as the standard. The values given in parentheses are provided for information only and are not considered standard. Reporting of test results in units other than SI shall not be regarded as nonconformance with this standard. 1.5 All observed and calculated values shall conform to the guidelines for significant digits and rounding established in Practice D6026 , unless superseded by this test method. 1.5.1 The procedures used to specify how data are collected/recorded and calculated in the standard are regarded as the industry standard. In addition, they are representative of the significant digits that generally should be retained. The procedures used do not consider material variation, purpose for obtaining the data, special purpose studies, or any considerations for the user’s objectives; and it is common practice to increase or reduce significant digits of reported data to be commensurate with these considerations. It is beyond the scope of these test methods to consider significant digits used in analysis methods for engineering data. 1.6 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 through the ASTM consensus process. 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. 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. ====== Significance And Use ====== 5.1 Landscaping and construction professionals and golf course designers are a few of the typical users of this standard. When physically evaluating a soil, relative to its suitability to support plant growth (primarily grasses), tests must be performed to determine the presence and amount of solid matter compatibility that is then used to determine potential air-void content, water-holding ability, and deleterious materials. Rotary kiln produced porous ceramic material is a mineral amendment that can be added to a topsoil to increase its suitability to support plant growth. 5.2 Typical general ranges of soil content for suitable topsoils are presented in Specification D5268 . It should be recognized, however, that in some geographic regions, concurrence with the values in the referenced table could be difficult. In such situations, locally acceptable specifications need to be developed. Note 1: The quality of the result produced by this standard is dependent on the competence of the personnel performing it and the suitability of the equipment and facility used. Agencies that meet the criteria of Practice D3740 are generally considered capable of competent and objective testing/sampling/inspection. Reliable results depend on many factors; Practice D3740 provides a means of evaluating some, but not all of those factors.
