SPECIFICATION RT-510 ISSUE 12
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
Flammability
Low Temperature Flexibility
Physical property tests performed at this time qualify subsequent sleeving lots produced from the same
batch of compound. Statistical process control data may be used to demonstrate conformance for
dimensions.
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 Range
1/8 through 7/8
1 through 4
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 175 ± 5°C (347 ± 9°F) oven. 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 61 m) per
minute. Tubing shall be allowed to cool to room temperature prior to testing. The Heat Shrinkable
Sleeving and Measurement Gages shall be at room temperature with ambient relative humidity prior to
testing before or after heat shrinking.
