1.1 本规范涵盖重力流管道、排水、废水和排气卫生设施以及雨水应用中使用的铸铁污水管和配件。它建立了标准，涵盖超重型和服务铸铁污水管和配件的材料、制造、机械和化学性能、涂层、测试方法、检查、认证、产品标记、尺寸和尺寸公差。这些管道和配件不适用于压力应用，因为卫生排水、废物、通风和雨水排放系统的适当尺寸选择允许自由空气空间用于重力排水。 1.2 本规范涵盖以下型式的管道和管件，当指定时，应适用于符合表1和表2中的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。 1.2.1 管道: 桌子 超重，2 1. / 2. 英尺（0.75米），3 1. / 2. 英尺（1.0米）、5英尺（1.5米）、10英尺（3.0米）长度 1, 2 服务，2 1. / 2. 英尺（0.75米），3 1. / 2. 英尺（1.0米）、5英尺（1.5米）、10英尺（3.0米） 1, 2 外部尺寸（用于详图） X1.1 1.2.2 配件: 桌子 1. / 4. 弯管；长的 1. / 4. 弯管 3, 4 1. / 4. 弯管，长低轮毂 5. 1. / 4. 弯曲，低跟；高跟鞋 6, 7 1. / 4. 弯曲、短扫描；长扫描 8. 1. / 4. 弯曲，减少长扫描 9 1. / 5. 弯管 10 1. / 6. 弯管 10 1. / 8. 弯管；长的 1. / 8. 弯管 11 1. / 16 弯管 11 Y分支 12, 13 Y分支，组合 1. / 8. 弯管，单 14 Y分支，组合 1. / 8. 弯管，双 14 卫生T形支管，单 15 卫生T形支管，双 15 卫生T形支管，清洗口 16 单螺纹卫生T形支管 17 双螺纹卫生T形支管 17 T支路，单支路和双支路 18 分接T分支，单 19 双抽头T形分支 19 T分支，清洗 20 -45°偏置管件 21 双轮毂 22 长双轮毂 22 异径管 23 增量器 24, 25 P陷阱 26, 27 深度密封P存水弯 28 运行陷阱 29 螺塞（黄铜） 30 盲塞 31 铁体套圈 32 侧进气口 图3 壁橱弯头 33 攻丝凸台 34 减少 1. / 4. 弯曲SV 35 组合Y和 1. / 8. 弯曲 36 “H”分支配件 37 1.3 以英寸-磅为单位的数值应视为标准值。括号中给出的值是到国际单位制的数学转换，仅供参考，不被视为标准值。 1.4 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 specification covers cast iron soil pipe and fittings for use in gravity flow plumbing, drain, waste and vent sanitary, and storm water applications. It establishes standards covering material, manufacture, mechanical and chemical properties, coating, test methods, inspection, certification, product markings, dimensions, and dimensional tolerances for extra-heavy and service cast iron soil pipe and fittings. These pipe and fittings are not intended for 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 This specification covers pipe and fittings of the following patterns and, when so designated, shall apply to any other patterns that conform with the dimensions found in Tables 1 and 2 and all other applicable requirements given in this specification. 1.2.1 Pipe: Tables Extra heavy, 2 1 / 2 ft (0.75 m), 3 1 / 2 ft (1.0 m), 5 ft (1.5 m), 10 ft (3.0 m) lengths 1, 2 Service, 2 1 / 2 ft (0.75 m), 3 1 / 2 ft (1.0 m), 5 ft (1.5 m), 10 ft (3.0 m) 1, 2 Outside dimensions (for detailing) X1.1 1.2.2 Fittings: Tables 1 / 4 bends; long 1 / 4 bends 3, 4 1 / 4 bends, long low-hub 5 1 / 4 bends, low heel; high heel 6, 7 1 / 4 bends, short sweep; long sweep 8 1 / 4 bends, reducing long sweep 9 1 / 5 bends 10 1 / 6 bends 10 1 / 8 bends; long 1 / 8 bends 11 1 / 16 bends 11 Y branches 12, 13 Y branches, combination 1 / 8 bends, single 14 Y branches, combination 1 / 8 bends, double 14 Sanitary T branches, single 15 Sanitary T branches, double 15 Sanitary T branches, cleanout 16 Tapped sanitary T branches, single 17 Tapped sanitary T branches, double 17 T branches, single and double 18 Tapped T branches, single 19 Tapped T branches, double 19 T branches, cleanout 20 -45° offset fitting 21 Double hubs 22 Long double hubs 22 Reducers 23 Increasers 24, 25 P traps 26, 27 Deep seal P traps 28 Running traps 29 Screw plugs (brass) 30 Blind plugs 31 Iron-body ferrules 32 Side inlets Fig. 3 Closet bends 33 Tapping bosses 34 Reducing 1 / 4 bend SV 35 Combination Y and 1 / 8 bend 36 ‘H’ branch fitting 37 1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 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.
