at the same time.

4.2 TEST PROCEDURES

Unless otherwise specified, tests shall be performed on specimens which have been fully recovered by

conditioning in accordance with 4.3.1. Prior to all testing, the test specimens (and measurement gauges,

when applicable) shall be conditioned for 3 hours at 23 ± 3ºC (73 ± 5ºF) and 50 ± 5 percent relative

humidity. All ovens shall be of the mechanical convection type in which air passes the specimens at a

Measure three 6-inch (150 mm) specimens of tubing, as supplied, for length ± 1/32 inch (± 1 mm) and inside

diameter in accordance with ASTM D 2671. Recover these specimens fully by conditioning for 3 minutes in

a 250 ± 5ºC (482± 9ºF) oven. Remove the specimens from the oven, allow to cool to 23 ± 3ºC (73 ± 5ºF) and

re-measure. Calculate longitudinal change as follows:

LC = L1 - L0

L0 X 100

Where: LC = Longitudinal Change [Percent]

L

0 = Length Before Conditioning [Inches (mm)]

L

1 = Length After Conditioning (Inches (mm)]

Measure the wall thickness of three 6-inch (150-mm) long specimens, as supplied, in accordance with ASTM

D 2671. Calculate concentricity as follows:

C = M1

M2 X 100

Where: C = Concentricity [Percent]

M

1 = Minimum Thickness [Inches (mm)]

M

2 = Maximum Thickness [Inches (mm)]

4.3.2 Tensile Strength and Ultimate Elongation

Test three specimens of tubing for tensile strength and ultimate elongation in accordance with ASTM D

2671. For tubing sizes 3/8 and smaller, use full sections of tubing. For sizes 1/2 and larger, cut the

specimens with Die D, ASTM D 412. Apply 1-inch (25-mm) centrally located benchmarks to the specimens.

Use an initial machine jaw separation of 1 inch (25 mm) for full sections of tubing and 2 inches (51 mm) for

die cut specimens. Test at a rate of jaw separation of 2.0 ± 0.2 inches (50 ± 5 mm) per minute.

4.3.3 Low Temperature Flexibility

Condition three specimens, each 12 inches (300 mm) in length, and a mandrel selected in accordance with

Table 2, at -65 ± 3ºC (-85 ± 5ºF) for 4 hours. For tubing sizes 3/4 or less, use whole sections of tubing

recovered on a stranded wire (nearest AWG which is larger than the tubing maximum inside diameter after

unrestricted shrinkage). For tubing sizes larger than 3/4, use 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 consisting of whole sections of tubing around the mandrel for

not less than 180 degrees in 10 ± 2 seconds. Wrap strip specimens around the mandrel for not less than 360

degrees in 10 ± 2 seconds. Examine the specimens visually for evidence of cracking.

4.3.4 Heat Shock

Condition three 6-inch (150-mm) specimens of tubing for 4 hours in a 300 ± 5ºC (572 ± 9ºF) oven. Remove

the specimens from the oven, cool to 23 ± 3ºC (73 ± 5ºF), wrap 360 degrees around a mandrel selected in

accordance with Table 2 and then visually examine for evidence of dripping, flowing or cracking. Any side

cracking caused by flattening of the specimen on the mandrel sh all not constitute failure.

4.3.5 Heat Resistance

Condition three 6-inch (150-mm) specimens prepared in accordance with 4.3.2 for 336 hours in a 250 ± 3ºC

(482 ± 5ºF) oven. After conditioning, the specimens shall be removed from the oven, cooled to 23 ± 3ºC (73

± 5ºF) and tested for tensile strength and ultimate elongation in accordance with 4.3.2.

4.3.6 Copper Stability

Slide three 6-inch (150-mm) specimens of tubing over a snug-fitting, straight, clean, bare solid or tubular

copper conductor. Condition the specimens on the conductors for 24 hours in an appropriate humidity

chamber at 90 to 95 percent relative humidity and 23 ± 3ºC (73 ± 5ºF), followed by 16 hours in a 200 ± 3ºC

(392 ± 5ºF) oven. After conditioning, remove the specimens from the oven and cool to 23 ± 3ºC (73 ± 5ºF).

Remove the copper conductor from the tubing and examine the tubing and conductor. Darkening of the

copper due to normal air oxidation shall not be cause for rejection. Test the tubing for ultimate elongation in

accordance with 4.3.2.

4.3.7 Corrosive Effect

Test the tubing for copper mirror corrosion in accordance with ASTM D 2671, Procedure A, for 16 hours at

200 ± 3ºC (392 ± 5ºF). Use specimens of 1/4 x 1 inch (6 x 25 mm) strips cut longitudinally from the tubing.

Evidence of corrosion shall be the removal of copper from the mirror, leaving an area of transparency greater

than 8 percent of its total area.

4.3.8 Fluid Resistance

Immerse three 6-inch (150-mm) specimens of tubing, prepared and measured in accordance with 4.3.2,

completely in each listed fluid for the time and temperature specified in Table 3. Use a volume of fluid not

less than 20 times that of the specimens. After immersion, lightly wipe the specimens and air-dry for 30 to

60 minutes at room temperature. Test the specimens from each fluid for tensile strength and ultimate

elongation in accordance with 4.3.2.

4.3.9 Flammability After Fluid Exposure

Flammability tests shall be performed in accordance with ASTM D 2671 Procedure C on a

22-inch (559-mm) length of the tubing that has been fully immersed for 24 hours with ends open in fluids

specified in Table 3. The outside of the tubing shall be wiped to remove excess fluid and mounted in the

apparatus. The inside of the tubing shall be allowed to drain for 5 minutes before flame is applied.

4.3.10 Radiation Resistance

Three specimens prepared in accordance with Section 4.3.2 shall be subjected to gamma radiation for a total

dosage of 10 Mrad at a rate of less than 0.5 Mrad per hour. The specimens shall be measured for tensile

strength and ultimate elongation in accordance with Section 4.3.2.

4.4 REJECTION AND RETEST

Failure of any sample to conform to any one of the requirements of the specification shall be cause for

rejection of the lot represented. Product which has been rejected may be replaced or reworked to correct the

defect and then resubmitted for acceptance. Before resubmitting, full particulars concerning the rejection and

the action taken to co rrect the defect shall be furnished to the inspector.

5. PREPARATION FOR DELIVERY

5.1 PACKAGING

Packaging shall be in accordance with good commercial practice.

5.2 MARKING

Each container of product shall be permanently and legibly marked with the manufacturer's part number, size,

quantity, manufacturer's identification, lot number and d ate of manufacture.
