1.1 本规范涵盖重力流应用中使用的无轮毂铸铁土壤管和配件。它制定了无轮毂铸铁土壤管和配件的材料、制造、机械和化学性能、尺寸、涂层、试验方法、检验、认证和产品标记等标准。这些管道和配件适用于非压力应用，因为选择适当尺寸的卫生排水、废物、通风和雨水排水系统可以为重力排水提供自由的空气空间。 1.2 本节中所示的EDP/ASA编号代表美国供应协会（ASA）采用的统一行业规范。 组名称前缀022分配给无轮毂产品，后面是分配给单个项目的四位标识和一个校验位。该系统旨在通过分销渠道促进EDP控制，并将普遍用于订购和指定产品项目。那些没有EDP编号的项目是新的、特殊的或暂时的，将在本规范的后续印刷品上分配编号。 1.3 本规范涵盖以下型式的管道和管件，并适用于符合表1和表2中尺寸以及本规范中给出的所有其他适用要求的任何其他型式。 2. 1.3.1 长度: 数字 EDP/ASA识别号 用于无轮毂管道 图1 尺寸为10英尺（3.0米），尺寸为5英尺（1.5米） 1. 1. / 2. , 2, 3, 4, 5, 6, 8, 10、12和15英寸。 图1、图2 指定配件的方法 图3 1.3.2 配件: 四分之一弯曲 图5 四分之一弯曲，异径 图6 四分之一弯曲，带侧开口 图7 四分之一弯曲，后跟开口 图8 四分之一弯曲，螺纹 图9 四分之一弯，双 图10 四分之一弯，长 图11 短扫描 图12 长扫描 图13 长扫描，减少 图14 第五个弯道 图15 第六弯 图16 第八弯 图17 第八弯，长 图18 第十六弯 图19 卫生三通 图20 带侧开口的卫生三通 图21 带2 in.侧开口R或L/R和L的卫生三通 图22 卫生三通，新奥尔良特别，带侧开口 图23 带有45°侧开口和新奥尔良的卫生三通 图24 卫生专用三通螺纹 图25 卫生螺纹三通，水平双 图26 卫生螺纹三通，双垂直 图27 Y分支 图28 Y分支，双 图29 Y分支，直立 图30 直立Y宽中心佛罗里达特辑 图31 Y分支，组合 1. / 8. 弯曲 图32 Y分支，组合 1. / 8. 双折弯 图33 卫生十字 图34 带侧开口的卫生十字 图35 卫生十字，新奥尔良，带侧开口 图36 卫生十字，新奥尔良，带45°特殊和 常规侧面开口 图37 卫生十字，螺纹 图38 测试三通 图39 螺纹接长件 图40 增量减速器 图41 增量减速器，短 图42 螺纹适配器 图43 盲塞 图44 铁体清洗口，螺纹 图45 P陷阱 图46 P陷阱，长 图47 P阱，深密封 图48 P存水弯，带底漆 图49 P存水弯，带螺纹入口 图50 螺纹入口，双 图51 改良组合Y形和 1. / 8. 弯曲，双 图52 改良组合Y形和 1. / 8. 弯曲，双，延伸 图53 双向清洗口 图54 双清洁口 图55 壁橱弯曲，规则和缩小 图56 壁橱法兰立管 图57 攻丝凸台 图58 双扫掠卫生三通（加长） 图59 带双通风口的跑步陷阱 图60 带螺纹或无毂侧入口的P型存水弯 图61 排气管Y形加长，双 图62 通气Tub Y形延伸偏移，左侧或右侧 图63 通风管Y形 图64 双双向清洗口 图65 1.4 以英寸表示的值- 磅单位应视为标准单位。括号中给出的值是国际单位制的数学转换，仅供参考，不被视为标准。 1.5 对本标准具有管辖权的委员会知道铸铁土壤管道研究所发布的另一个可比标准，CISPI 301。 注1: 本标准的文本引用了提供解释性材料的注释和脚注。这些注释和脚注（不包括表和图中的注释和脚注）不应被视为本标准的要求。 1.6 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。

1.1 This specification covers hubless cast iron soil pipe and fittings for use in gravity flow applications. It establishes standards covering material, manufacture, mechanical and chemical properties, dimensions, coating, test methods, inspection, certification, and product marking for hubless cast iron soil pipe and fittings. These pipe and fittings are intended for non-pressure applications, as the selection of the proper size for sanitary drain, waste, vent, and storm drain systems allows free air space for gravity drainage. 1.2 The EDP/ASA numbers indicated in this section represent a Uniform Industry Code adopted by the American Supply Association (ASA). A group designation prefix, 022, is assigned to hubless products, followed by the four-digit identification assigned to individual items and a check digit. This system has been instituted to facilitate EDP control through distribution channels, and is to be used universally in ordering and specifying product items. Those items with no EDP numbers are either new, special, or transitory and will be assigned numbers on subsequent prints of this specification. 1.3 This specification covers pipe and fittings of the following patterns and applies to any other patterns that conform with the dimensions found in Tables 1 and 2 and all other applicable requirements given in this specification. 2 1.3.1 Lengths: Figures EDP/ASA Identification Numbers for Hubless Pipe Fig. 1 10 ft (3.0 m) in sizes and 5 ft.

The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.5 The committee with jurisdiction over this standard is aware of another comparable standard published by the Cast Iron Soil Pipe Institute, CISPI 301. Note 1: The text of this standard references notes and footnotes that provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard. 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.
