UL 224. VERSAFIT V2 also meets the requirements of Standard C22.2 No. 198.1 and is CSA certified.
VERSAFIT V4, a thin wall very flexible 125°C, 300 volt, VW-1 rated, UL recognized tubing meeting the
requirements of UL 224. VERSAFIT V4 also meets the requirements of Standard C22.2 No. 198.1 and is
CSA certified with a 150 volt rating.

3. REQUIREMENTS
3.1 MATERIAL
The tubing shall be fabricated from thermally stabilized, flame-retardant, modified polyolefin and shall be
crosslinked by irradiation. It shall be homogeneous and essentially free from flaws, defects, pinholes,
bubbles, seams, cracks and inclusions.
3.2 PROPERTIES
The tubing shall meet the requirements of Table 3.
3.3 COLOR
The tubing shall be available in black, white, red, yellow, blue, green, brown, orange, violet and gray.
4. QUALITY ASSURANCE PROVISIONS
4.1 CLASSIFICATION OF TESTS
4.1.1 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.
4.1.2 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
Ultimate Elongation
4.2 SAMPLING INSTRUCTIONS
4.2.1 Qualification Test Samples
Qualification test samples shall consist of 15m (50 feet) of tubing of the size and color specified.
Qualification of one size or color shall qualify all sizes and colors.
4.2.2 Acceptance Test Samples
Acceptance test samples shall consist of not less than 5m (16 feet) 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.
4.3 TEST PROCEDURES
Unless otherwise specified, tests shall be performed on specimens which have been fully recovered by
conditioning in accordance with 4.3.1 Prior to all testing, the test specimen (and measurement gauges, when
applicable) shall be conditioned for 3 hours at 23 ± 3°C (73 ± 5°F) and 50 ± 5 percent relative humidity. All
ovens shall be of the mechanical convection type in which air passes the specimens at a velocity of 30 - 60m
(100 to 200 feet) per minute.

4.3.1 Dimensions and Longitudinal Change
Three 150mm (6 inch) specimens of tubing, as supplied, shall be measured for length, to an accuracy of
± 1 mm 1/32 inch) and inside diameter in accordance with ASTM D 2671. The specimens then shall be
conditioned for 3 minutes in a 200 ± 3°C (392 ± 5°F) oven, removed from the oven, cooled to 23 ± 3°C
(73 ± 5°F), re-measured for length, inside diameter and wall thickness in accordance with ASTM D 2671.
The longitudinal change shall be calculated as follows:
C = L1 - L0
L0 x 100
Where: C = Longitudinal Change (percent)
L0 = Length Before Conditioning [mm (inches)]
L1 = Length After Conditioning [mm (inches)]
4.3.2 Tensile Strength and Ultimate Elongation
The tensile strength and ultimate elongation of the tubing shall be determined in accordance with
ASTM D 2671 using 25mm (1 inch) bench marks and a 25 mm (1 inch) initial jaw separation. The speed of
jaw separation shall be 500 ± 50 mm (20 ± 2 inches) per minute.
4.3.3 Secant Modulus
The secant modulus of the tubing shall be tested using tubing as supplied in accordance with ASTM D 2671.
4.3.4 Copper Stability
Three 150mm (6 inch) specimens of tubing shall be slipped over a snug filling, straight, clean, bare copper
conductor. For tubing sizes 1/4 and smaller a solid conductor shall be used; for tubing sizes 3/8 and larger a
solid or tubular conductor shall be used. The specimens on the conductors shall be conditioned for 24 hours
in a desiccator or similar humidity chamber at 90 to 95 percent relative humidity and 23 ± 3°C (73 ± 5°F)
(three specimens shall be conditioned for 7 days in 158.0 ± 1.0°C (316.4± 1.8°F) oven. After conditioning,
the specimens shall be removed from the oven and cooled to 23 ± 3°C (73 ± 5°F). The copper conductor then
shall be removed from the tubing, the tubing and conductor shall then be examined. Darkening of the copper
due to normal air oxidation shall not be cause for rejection. The tubing then shall be conditioned at room
temperature for 16 to 96 hours and tested for ultimate elongation in accordance with 4.3.2.
4.3.5 Dielectric Withstand, Breakdown and Strength
The dielectric strength of the tubing shall be measured under oil in accordance with ASTM D 2671. Five
150mm (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.
4.3.6 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.
4.4 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.
