   Rectangular speicimen for wall thickness less than 5/16″; min % in 2 in (1/2″ wide specimen)	B	B

   Where the wall thickness lies between two values above, the min elongation value is determined by the following equations:

   Longitudinal E=48t+15.00

   Transverse E=32t+10.00

   E = elongation in 2in [50mm], %

   t = actual thickness of specimen, in [mm]
