VERSAFIT® TUBING

Polyolefin, Flexible, Heat-Shrinkable, Flame Retardant

1. 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.

2. APPLICABLE DOCUMENTS

bubbles, seams, cracks, and inclusions.

3.2 PROPERTIES

The tubing shall meet the requirements of Table 2.

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

Statistical process control data may be used to demonstrate conformance for dimensions.

4.2 SAMPLING INSTRUCTIONS

4.2.1 Qualification Test Samples

Qualification test samples shall consist of 15mm (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 5 m (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 - 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 = 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 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. PREPARATION FOR DELIVERY

5.1 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.
