5. RESULTS
5.1 Calculation. The elongation of the specimen shall be calculated as follows:
Elongation, percent=D-G x100
G
where:
D=the distance between the bench marks at the moment of rupture of the specimen, inches
G=the distance between the bench marks on the unstretched specimen, inches
5.2 Unless otherwise specified in the detail specification, three specimens from each inspection unit shall
be tested except that under the following conditions five specimens shall be tested:
5.2.1 If the elongation of one or more specimens does not meet the specified requirement for elongation
in the detail specification.
5.2.2 If referee tests are being made.
5.3 The elongation of the insulation or sheath of the inspection unit shall be the median of the results
