homogeneous and essentially free from flaws, defects, pinholes, cracks, and inclusions.
3.2 COLOR
The tubing shall be black.
3.3 PROPERTIES
The tubing shall meet the requirements of Table 3.
4. QUALITY ASSURANCE PROVISIONS
4.1 CLASSIFICATION OF TESTS
4.1.1 Qualification Tests
Qualification tests are those performed on samples submitted for qualification as representative of standard
product and shall consist of all tests listed in this specification.
4.1.2 Acceptance Tests

4.2 SAMPLING INSTRUCTIONS
4.2.1 Qualification Test Samples
Qualification test samples shall consist of sufficient lengths of Sizes 0500 and 1500. These two sizes will
qualify all sizes as follows. For Fluid Resistance, one size shall qualify all sizes.
Qualification Size Qualification Range
0500 Below 1000
1500 1000 and above
4.2.2 Acceptance Test Samples
Acceptance test samples shall consist of not less than 10 feet (3 m) of tubing selected at random from each
lot. A lot shall consist of all tubing of the same size, from the same production run, and offered for
inspection at the same time.
4.3 TEST PROCEDURES
4.3.1 Tensile Properties (Tensile Strength & Extensibility)
Test three 6-inch (150-mm) specimens of tubing, [cut 6 x 1/2 inch (150 x 12 mm) strips from tubing larger
than Size 0437], in accordance with ASTM D 638, using an initial jaw separation of 3 inches (76 mm), 2-inch
(50-mm) bench marks and a 2-inch (50-mm) per minute rate of jaw separation. Measure the benchmark
separation and load at break. Report these values as the extensibility and tensile strength, respectively.
4.3.2 Crush Resistance
Cut three specimens of tubing to provide the number of convolutions specified in Table 1. Place each
specimen horizontally between plates larger than 2 inches (50 mm) square in a standard tensile testing
machine that is arranged to measure and record compressive force. Operate the machine at a compressive
speed of 0.2 inches (5 mm) per minute. Measure the average force required to reduce the outside diameter of
the tubing by 25 percent and report this force as the crush resistance.
