scope:

This standard covers 3-in. through 24-in. gray-iron pipe centrifugally cast in metal molds for water or other liquids. Characteristics of such pipe with push-on joints, and mechanical joints arc given in the tables. This standard may be used for pipe with such other types of joints as may be agreed upon at the time of purchase. The thicknesses. weights, and strength test requirements shown in this standard are for pipe with 18/40 iron strength 18000 psi (124.1MPa) minimum bursting tensile and 40 000 psi (275.8 M Pa) minimum ring modulus of rupture).
