Scope
本标准规定了经任何类型铸造工艺加工或由铸铁部件装配而成的水及燃气用球墨铸铁管、管件、附件及其接口的术语和定义、技术要求、试验方法、尺寸和公差、检验规则与质量证明书等，也给出了接口部件的型式试验要求。
本标准适用于包含有承口、插口或法兰，一般以内部和外部涂覆状态交货的管、管件、附件及其接口，尺寸范围为DN40～DN3000，流体温度为0 ℃～50 ℃，适用范围如下：
——用于各种用途不同类型水的输送；
——有压或无压输送；
——地下或地上铺设；
——设计压力为中压A级及以下级别的燃气(如人工煤气、天然气、液化石油气等） 输送。
本标准不适用于输送冰点以下温度(这并不排除产品用于较高温度）的流体。
管和管件依据允许工作压力或壁厚进行分级。
注： 本标准中所有压力均为相对压力，单位为兆帕（MPa）。
