7. Description of Test Equipment
7.1 A test apparatus capable of securing the test
specimen while accurately providing a uniform rate
of pull to the specimen. The test instrument shall
have the capability of recording the maximum tensile
force applied to the test specimen.
7.2 See Figure 1 for basic tensile test apparatus.

Basic Tensile Test Apparatus
8. Safety Precautions
WARNING: This test method will subject test
specimens to conditions that may exceed the
normal performance rating of the products
under evaluation. Adequate precautions
must be taken to prevent injury to the person
conducting the test.
9. Test Specimens and Conditioning
9.1 Sample Size A minimum of three specimens
shall be tested.
9.2 Specimen Size The specimen length shall be
no less than 10 cm (4 in) between the tensile fixture
and the tube end of the fitting connection.
9.3 Specimen Surface All surfaces of the
specimens shall be free of visible flaws, scratches, or
other imperfections, unless typically found on a
representative sample of the product.
9.4 Specimen Conditioning All specimens must
be conditioned for a minimum of one hour in an air
environment of 23° ± 2.8°C (73° ± 5°F) prior to
being subjected to tensile forces.
10. Calibration
10.1 Calibrate the tensile test equipment's rate of
pull to 2.5 cm (1 in) per minute, ± 5%.
10.2 Calibrate the tensile force instrument to ± 2%
full scale.
11. Test Procedure
11.1 Assemble a test fitting connection, per
manufacturer's specification, to one end of the tube.
(See 9.2.)
11.2 Install the fitting connection to the tensile
fixture (see Figure 1) in a manner that prevents
distortion of the connection.
11.3 Secure the open end of the tube to the tensile
fixture, leaving a minimum of 10 cm (4 in) of
exposed tube.
11.4 Begin pulling the test specimen at a rate of 2.5
cm (1 in) per minute.
11.5 Continue applying tensile force until the tube
pulls through the fitting connection or until tearing of
the tube occurs.
11.5.1 If the tube releases from the tensile fixture,
the data from that specimen must be disregarded and
an additional specimen tested.
11.6 Record on test data sheet (see Appendix 1 for a
sample) the mode of failure and the maximum tensile
force applied, in Newtons (lbs).
12. Calculations
12.1 Calculate the average "maximum tensile force"
and record.
12.2 Calculate the standard deviation of "maximum
tensile force" and record.
13. Data Accuracy
13.1 Tensile Force Newtons: ± 2%.
14. Test Data Sheet
The test data sheet shall include the following
information:
