SPECIFICATION RT-1116 Issue 6
REQUIREMENTS
MATERIAL
The tubing shall be fabricated from a stabilized, flame resistant, modified elastomer and shall be radiation
crosslinked. It shall be homogeneous and essentially free from flaws, defects, pinholes, bubbles, seams,
cracks, and inclusions.
COLOR
The tubing shall be black.
PROPERTIES
The tubing shall meet all the requirements of Table 3.
QUALITY ASSURANCE PROVISIONS
CLASSIFICATION OF TESTS
Qualification Tests
Qualification tests are those performed on tubing submitted for qualification as a satisfactory product and
shall consist of all tests listed in this specification.
Acceptance Tests
Acceptance tests are those performed on tubing submitted for acceptance under contract. Acceptance tests
shall consist of the following: dimensions, longitudinal change, tensile strength, tensile stress, ultimate
elongation, heat shock, hardness, flammability, and low temperature flexibility.
SAMPLING INSTRUCTIONS
Qualification Test Samples
Qualification test samples shall consist of 50 feet (15 m) of tubing of each size. Qualification of any size
within each size range specified below will qualify all sizes in the same range.
Size Ranges
1/4 through 3/4
1 through 3
Acceptance Test Samples
Acceptance test samples shall consist of not less than 16 feet (5 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.
TEST PROCEDURES
Unless otherwise specified, tests shall be performed on specimens which have been fully recovered by
conditioning for 10 minutes in a 200 ± 2°C (392 ± 4°F) oven. Prior to all testing, the test specimens (and
measurement gauges, when applicable) shall be conditioned for 3 hours at
23 ± 3°C (73 ± 5°F) and 50 ± 5 percent relative humidity. All ovens shall be of the mechanical convection
type in which air passes over the specimens at a velocity of 100 to 200 feet (30 to 60 m) per minute.
Dimensions and Longitudinal Change
Three 6-inch (150-mm) specimens of tubing, as supplied, shall be measured for length ± 1/32 inch (± 1 mm)
and inside diameter in accordance with ASTM D 2671, conditioned for 10 minutes in a
200 ± 2°C (392 ± 4°F) oven, cooled to 23 ± 3°F (73 ±5°F) and then remeasured. Prior to and after
conditioning, the dimensions of the tubing shall be in accordance with Table 1 and the longitudinal change
shall be in accordance with Table 3. Longitudinal change shall be calculated as follows:
C =
L1 - L0
L0
x 100
WHERE:
C =
L0 =
L1 =
Longitudinal Change (percent)
Length Before Conditioning [inches (mm) ]
Length After Conditioning [inches (mm) ]
