4.3.10 Fluid Resistance
Prepare six specimens, three 6-inch (150-mm) tubing specimens and three tensile specimens prepared and
measured in accordance with Section 4.3.1, and immerse for the time and temperature specified for each of
the test fluids listed in Table 3. The volume of the fluid shall not be less than 20 times that of the specimens.
Before and after immersion, rinse the specimens in methyl ethyl ketone to remove surface contamination and
fluid residues. After immersion and rinsing, wipe the specimens lightly and air dry for 30 to 60 minutes at 23
± 3°C (73 ± 5°F). Test the three specimens intended for the Tensile Strength and extensibility tests in
accordance with Section 4.3.1. Weigh the other three specimens before and after immersion and calculate
the weight change as a percentage. Report the average of the three values.
4.3.11 Flammability
Perform flammability in accordance with ASTM D 876, except that the bottom of the chamber shall be
within 9 inches (229 mm) of the point of flame impingement and covered with surgical cotton. Observe any
ignition of the cotton from dripping or falling particles.
4.4 REJECTION AND RETEST
Failure of any sample of tubing to conform to any one of the requirements of this specification shall be cause
for rejection of the lot represented. Tubing which has been rejected may be replaced or reworked to correct
the defect and then resubmitted for acceptance. Before resubmitting, full particulars concerning the rejection
and the action taken to correct the defect shall be furnished to the inspector.
5. PREPARATION FOR DELIVERY
5.1 PACKAGING
Unless otherwise specified, the tubing shall be supplied coiled on spools or reels and shall be packaged in
accordance with good commercial practice.
5.2 MARKING
Each spool or reel of tubing shall be permanently and legibly marked with the size, color, quantity,
manufacturer’s identification, part number, and lot number.
