| A Applies to specified wall thicknesses (t) equal to or greater than
0.120 in. (3.05 mm). For lighter specified wall thicknesses, the
minimum elongation values shall be calculated by the formula:
percent elongation in 2 in. (50mm) = 56t + 17.5, rounded to the
nearest percent. For A500M use the following formula: 2.2t + 17.5,
rounded to the nearest percent. B Applies to specified wall thicknesses (t) equal to or greater than 0.180 in. (4.57 mm). For lighter specified wall thicknesses, the minimum elongation values shall be calculated by the formula: percent elongation in 2 in. (50 mm) = 61t + 12, rounded to the nearest percent. For A500M use the following formula: 2.4t + 12, rounded to the nearest percent. C Applies to specified wall thicknesses (t) equal to or greater than 0.120 in. (3.05 mm). For lighter specified wall thicknesses, the minimum elongation values shall be by agreement with the manufacturer. D The minimum elongation values specified apply only to tests performed prior to shipment of the tubing. | ||||
