Dimensions and Longitudinal Change
Measure three 6 inch (152 mm) specimens of tubing, as supplied, for length ± 1/32 inch
(± 1 mm) and inside diameter in accordance with ASTM D 2671. Condition these
specimens for 10 minutes in a 200 ± 5°C (392 ± 9°F) oven or equivalent, cool to 23 ±
3°C (73 ± 5°F) and then remeasure. Calculate longitudinal change as follows:
C =
L1 - L0

x 100

Tensile Strength, Tensile Stress and Elongation
Test three specimens of tubing for tensile strength, tensile stress and elongation in
accordance with ASTM D 2671. For tubing sizes 3/8 and smaller, the specimens shall be
full sections of tubing; for sizes 1/2 and larger, the specimens shall be cut with die D of
ASTM D 412. The specimens shall have1 inch (25 mm) bench marks centrally located.
The testing machine shall have an initial jaw separation of 1 inch (25 mm) for full
sections of tubing and 2 inches (51 mm) for die-cut specimens. The rate of jaw separation
shall be 20 ± 2 inches (508 ± 50 mm) per minute.
Low Temperature Flexibility
Condition three specimens, each 12 inches (300 mm) in length and a mandrel selected in
accordance with Table 2, at -65 ± 5°C (-85 ± 9°F) for 4 hours. For tubing sizes 3/4 or
less, the specimens shall be whole sections of tubing recovered on a stranded wire
(nearest AWG which is larger than the sleeving maximum inside diameter after
unrestricted shrinkage). For tubing sizes larger than 3/4, the specimens shall be 1/4-inch
(6.3 mm) wide strips cut from tubing which has been recovered in accordance with 4.3.1.
After 4 hours conditioning and while still at the conditioning temperature, wrap the
specimens around the mandrel for not less than 360 degrees in 10 ± 2 seconds then
visually examine the specimens for evidence of cracking.
Heat Shock
Three 6 inch (152 mm) specimens of tubing shall be conditioned for 4 hours in a 225 ±
5°C (437 ± 9°F) oven. After conditioning, remove the specimens from the oven, cool to
room temperature and bend through 180 degrees in 2 to 4 seconds over a mandrel
selected in accordance with Table 2. Visually examine the specimens for evidence of
dripping, flowing or cracking. Any side-cracking caused by flattening of the specimen on
the mandrel shall not constitute failure.
