1.1 本指南涵盖适用于棒球场和垒球场蒙皮区域的施工和维护的技术。本指南提供了材料选择指南，如土壤、砂、砾石、碎石、碎砖、煅烧粘土、煅烧硅藻土、玻化粘土等，用于建造或修复剥皮区域，以及选择将保持安全和可玩的剥皮表面的管理做法。虽然本指南专门针对棒球/垒球，但它适用于球反弹、滚球或球员站位或其组合很重要的其他运动。 1.2 选择施工和维护技术的决定受现有土壤类型、气候因素、发挥水平、使用强度、可用设备、预算以及管理人员的培训和能力的影响。 1.3 以国际单位制表示的数值应视为标准。括号中的值仅供参考。 1.4 本标准可能涉及危险材料、操作和设备。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。 1.5 本指南提供了有组织的信息收集或一系列选项，并不推荐具体的行动方案。本文件不能取代教育或经验，应与专业判断一起使用。并非本指南的所有方面都适用于所有情况。ASTM标准无意代表或取代必须根据其判断给定专业服务的充分性的谨慎标准，也不应在不考虑项目的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。 1.6 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。 ====意义和用途====== 4.1 棒球场和垒球场的蒙皮区域应提供高质量的均匀运动表面。球反弹应该是真实的和可预测的。基础和滑动性能应有利于球员的最佳表现。起伏、粗糙表面、硬或软表面、杂草、石头和湿点都会影响良好的比赛。球场表面质量在很大程度上受施工和维护程序的影响，本标准指南阐述了这些程序。 虽然警告跑道是棒球场和垒球场上的一种蒙皮区域，但本标准不适用于警告跑道。单独的标准、指南 F2270页 ，显示与警告轨迹有关的信息。 4.1.1 施工期间，应考虑该区域所用材料的物理和化学性质、无石块和其他碎屑、表面和内部排水等因素。 4.1.2 影响表面可玩性的维护实践包括封边、拖拉、滚动、浇水、植被控制、刷洗或冲洗，以防止在剥皮/铺草皮边缘的草皮中堆积矿物质，以及清除可能对游戏和安全产生不利影响的石块和碎片。 4.2 负责棒球场和垒球场蒙皮区域的设计、施工或维护或其组合的人员将受益于本指南。 4.3 本指南提供了程序选择的灵活性，可用于涵盖各种使用和预算水平。

1.1 This guide covers techniques that are appropriate for the construction and maintenance of skinned areas on baseball and softball fields. This guide provides guidance for the selection of materials, such as soil, sand, gravel, crushed stone, crushed brick, calcined clay, calcined diatomaceous earth, vitrified clay, etc., for use in constructing or reconditioning skinned areas and for the selection of management practices that will maintain a safe and playable skinned surface. Although this guide is specific to baseball/softball, it has application to other sports where ball bounce, ball roll, or player footing, or a combination thereof, are of importance. 1.2 Decisions in selecting construction and maintenance techniques are influenced by existing soil types, climatic factors, level of play, intensity of use, equipment available, budget, and training and ability of management personnel. 1.3 The values stated in SI units are to be regarded as the standard. The values in parentheses are for information only. 1.4 This standard may involve hazardous materials, operations, and equipment. 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. 1.5 This guide offers an organized collection of information or a series of options and does not recommend a specific course of action. This document cannot replace education or experience and should be used in conjunction with professional judgment. Not all aspects of this guide may be applicable in all circumstances. The 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. 1.6 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 skinned areas of baseball and softball fields should provide a uniform playing surface of high quality. Ball bounce should be true and predictable. Footing and sliding properties should favor optimum performance of players. Undulations, rough surface, hard or soft surfaces, weeds, stones, and wet spots detract from good play. Playing surface quality is largely affected by construction and maintenance procedures, and this standard guide addresses those procedures. While warning tracks are a type of skinned area found on baseball and softball fields, this standard does not apply to warning tracks. A separate standard, Guide F2270 , presents information pertaining to warning tracks. 4.1.1 During construction, consideration should be given to factors such as the physical and chemical properties of materials used in the area, freedom from stones and other debris, and surface and internal drainage. 4.1.2 Maintenance practices that influence the playability of the surface include edging, dragging, rolling, watering, vegetation control, brushing or hosing to prevent buildup of a lip of mineral matter in turfgrass at the skinned/turfed edges, and removal of stones and debris that may adversely affect play and safety. 4.2 Those responsible for the design, construction, or maintenance, or a combination thereof, of skinned areas on baseball and softball fields will benefit from this guide. 4.3 This guide provides flexibility in choices of procedures and can be used to cover a variety of use and budget levels.
