7.18.4.1 The specimen shall be clamped and the required load shall be applied gradually to the
specimen.
7.18.4.2 If the load is applied using a tensile test machine, the tension shall be increased by separating
the clamps at a rate of 50 mm/min (2 in/min) ±10% until the specified load is reached. The load shall be
maintained for the specified duration, after which time it shall be removed.
7.18.4.3 If the load is applied by the lifting of a weight, the weight shall be centered directly under the
lifting point and shall be prevented from rotating. The load shall be maintained for the specified duration
after which the load shall be removed.
7.18.4.4 The specimen shall be observed to determine if any conductor breaks during the test as
evidenced by the specimen’s inability to support the full load applied for the specified duration.
