SPECIFICATION RW-3009 ISSUE 3
Dielectric Withstand, Breakdown, and Strength
The dielectric strength of the tubing shall be measured under oil in accordance with ASTM D 2671. Five
150-mm (6-inch) specimens of tubing shall be recovered over a metal mandrel by conditioning for 3 minutes
in a 200 ± 3°C (392 ± 5°F) oven. The mandrel diameter shall be slightly larger than the fully recovered
inside diameter of the tubing being tested. The metal mandrel shall serve as one electrode and a 25mm (1-
inch) wide strip of lead foil wrapped around the outside of the tubing as the other electrode. The test voltage
shall be applied at a rate of rise of 500 volts per second. Thickness measurements for calculating dielectric
strength shall be made adjacent to the point of breakdown. Specimens for dielectric withstand shall be held
for 60 seconds at 2500 volts.
Corrosive Effect
Three specimens of tubing shall be tested for copper contact corrosion in accordance with ASTM D 2671,
Procedure B. Three specimens shall be conditioned for 7 days in a 158.0 ± 1.0°C (316.4 ± 1.8°F) oven.
After conditioning, the specimens shall be visually examined for evidence of corrosion.
REJECTION AND RETEST
Failure of any samples 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.
PREPARATION FOR DELIVERY
FORM
The tubing shall be supplied on spools, unless otherwise specified.
PACKAGING
Packaging shall be in accordance with good commercial practice.
MARKING
Each container of tubing shall be permanently and legibly marked with the size, quantity, manufacturer's
identification, specification number, product designation, and lot number.
