VERSAFIT® TUBING

Polyolefin, Flexible, Heat-Shrinkable, Flame Retardant

SCOPE

This specification covers the requirements for one type of flexible electrical insulating, extruded tubing

whose diameter will reduce to a predetermined size upon the application of heat in excess of 90°C (194°F).

This tubing meets the requirements of SAE-AMS-DTL-23053/5 with a continuous operating temperature

range of -55° C to +135° C. Versafit is free of polybrominated biphenyls (PBB) and polybrominated

biphenyl oxides (PBBO). Versafit is also a 125°C, VW-1 rated, UL recognized tubing meeting the

requirements of UL 224 as well as meeting the requirements of Standard C22.2 No. 198.1 and is CSA

certified.

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 - 60 m

(100 to 200 feet) per minute.

4.3.1

Dimensions and Longitudinal Change

Three 150-mm (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 =

Where:

L1 - L0

x 100

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 25-mm (1-inch) benchmarks 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 150-mm (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

than shall be removed from the tubing, and 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

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.

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.

5.1

PREPARATION FOR DELIVERY

FORM

The tubing shall be supplied on spools, unless otherwise specified.

5.2

PACKAGING

Packaging shall be in accordance with good commercial practice.

5.3

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.

If this document is printed it becomes uncontrolled. Check for the latest revision.
