6.5 pressure containing envelope — The internal area

of a specimen which contains the fluid media.

6.6 standard deviation — A measure of the variation

among the members of a statistical sample.

6.7 subject — To expose to.

7 Description of Test Equipment

7.1 This test method requires the use of two hydraulic

systems.

7.1.1 A high pressure system capable of applying a

continuous increase of the internal hydraulic pressure to

the test specimen.

7.1.2 A low pressure, high temperature circulation

system capable of controlling a fluid temperature within

± 3°C (± 5°F) of a specified test temperature.

7.1.2.1 The pressure is to be 75 kPa (11 psig) or less

for all temperatures, within the range of 25° to 200°C

(77° to 392°F).

7.2 Test Fluid — When testing at or below 82°C

(180°F), an SAE 20 weight hydraulic oil may be used.

When testing at elevated fluid temperatures, use a

synthetic oil that is acceptable for elevated temperatures

of up to 200°C (392°F) and compatible with the test

stand and test specimens.

7.3 An instrument to record the peak pressure within

1% of full scale.

7.4 An instrument to monitor temperature within ±

1°C (± 2°F).

7.5 Specimen Support — Any support is acceptable as

long as it does not contribute to the restraint of the

specimen in either the circumferential or axial direction.

7.6 An enclosure that will allow observation of the test

specimen and that is also capable of controlling the

ambient temperature to 31° ± 6°C (88° ± 11°F).

7.7 See Figure 1 for basic pressure and circulation

system.

8 Safety Precautions

WARNING: This test method will subject test

specimens to conditions that exceed the

normal performance rating of the product

under evaluation. Adequate precautions must

be taken to prevent injury to the person

conducting the test, as catastrophic failures of

the test specimens are expected. The hydraulic

plumbing and safety enclosure is to be

constructed of materials which are capable of

containing a fluid at 200°C (392°F).

9 Test Specimens and Conditioning

9.1 Sample Size — A minimum of three specimens

shall be tested at each temperature condition.

9.1.1 The three connections will be conditioned

simultaneously. See Figure 1 for a basic pressure and

circulation system.

9.2 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.

9.3 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 pressure.

9.4 A fluid at the specified temperature must be

circulated through all the test specimens for a minimum

of one-half hour.

10 Test Procedure

10.1 Install three fitting connections, assembled per

manufacturer’s specifications, to the test system. Allow

for a minimum of 30 cm (12 in.) of tube length between

the test fitting connection and the free end closure.

10.2 The plumbing must permit free movement of

each test specimen to allow for distortion.

10.3 Using the low pressure circulation system (see

Section 7.1.2), condition the test specimens to 25°C

(77°F) per 9.4. The system pressure is not to exceed 75

kPa (11 psig) during conditioning.

10.4 Properly position the isolation valves in such a

way that only one specimen will be pressure tested,

while the remaining specimens continue to have heated

fluid circulating through them.

WARNING: Take all necessary precautions when

positioning the isolation valves, due to the potential

harm which might be caused by an accidental

exposure to the high temperature fluid.

10.4.1 Test each specimen within two minutes after

isolating it from the hot oil circulation system.

10.5 Using the high pressure system (see Section

7.1.1), pressurize the specimen until failure occurs.

10.5.1 Increase the pressure at a uniform and constant

rate such that failure occurs between 60 to 70 seconds

from initial exposure to the high pressure fluid.

10.6 Record on test data sheet (see Appendix 1 for

sample test data sheet) the pressure and temperature at

which the failure occurred. To identify mode of failure,

record pressure reading under column:

“T” — for tube failure.

“F” — for fitting connection failure.

10.7 Repeat 10.1 through 10.5, substituting, for the

fluid temperature in Section 10.2, the remaining six

temperatures: 75°C (167°F), 100°C (212°F), 125°C

(257°F), 150°C (302°F), 175°C (347°F), and 200°C

(392°F).

11 Calculations

11.1 Calculate the average pressure for each test

temperature and record in kPa (psig).

11.2 Calculate the standard deviation for each test

temperature and record.

12 Data Accuracy

12.1 Pressure — kPa: ± 2%

12.2 Fluid Temperature — ± 1°C (± 2°F)

13 Test Data Sheet

The test data sheet shall include the following

information:

13.1 Date tested.

13.2 Operator and test facility.

13.3 Description of items tested, including:

Tubing — manufacturer, O.D., wall thickness, part

number, and material type.

Fitting — manufacturer, type, size, part number, and

material type.

13.4 The actual temperature for each test.

13.5 The failure pressure for each sample, in the

appropriate column.

13.6 The average and standard deviation for each

failure mode of each specimen.
