RAYCHEM TAT-125 ADHESIVE LINED TUBING

Polyolefin, Flexible, Heat-Shrinkable, Dual Wall

1. SCOPE

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

whose diameter will reduce to a p r edetermined size upon the application of heat in excess of 121°C (250°F).

1.1 FORM

The tubing shall b e flame retarded an d shall be black with a th ermoplastic h ot melt adhesive lining, unless

otherwise specified.

2. APPLICABLE DOCUMENTS

This specification takes precedence over documents referenced herein. Unless otherwise specified, the latest

issue of referenced documents applies. The following documents form a part of this specification to the

extent specified herein.

3. REQUIREMENTS

3.1 MATERIALS

The tubing shall be fabricated from thermally stabilized, modified polyolefin and shall be crosslinked by

irradiation. It shall be homogeneous and essentially free from flaws, defects, pinholes, bubbles, seams,

cracks, and inclusions. It shall have an interior coating of thermoplastic adhesive.

3.2 PROPERTIES

The tubing shall meet the requirements of Table 3.

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 be: dimensions, longitudinal change, tensile strength, ultimate elongation, secant modulus, flammability

(jacket only), and heat shock. 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 cons ist of 50 feet (15 m) of black tubing. Qualification of any size within

each size range specified below shall qualify all sizes within that size range.

Range of Sizes

1/8 through ¼

3/8 through 1

1-1/2 through 4

4.2.2 Acceptance Test Sample

Acceptance test samples shall consist of not less than 16 feet (5 m) of tubing selected at random from each

compound batch or the first sleeving production lot of the batch compound. Physical property tests

performed at this time qualify subsequent sleeving lots produced from the same compound batch.

4.3 TEST PROCEDURES

Unless otherwise specified, perform tests on specimens which have been fully recovered by conditioning for

5 minutes in a 150 ± 5°C (302 ± 9°F) oven. Condition the test specimens (and measurement gauges, when

applicable) for 3 hours at 23 ± 3°C (73 ± 5°F) and 50 ± 5 percent relative humidity prior to all testing. Use

mechanical convection type ovens in which air passes the specimens at a velocity of 100 to 200 feet (30 to 60

m) per minute.

4.3.1 Dimensions and Longitudinal Change

Measure three 6-inch (150 mm) specimens of tubing, as supplied, for length ± 1/32 inch

(± 1 mm), and inside diameter in accordance with ASTM D 2671. Condition the specimens for 5 minutes in

a 150 ± 5°C (302 ± 9°F) oven, cool to 23 ± 3°C (73 ± 5°F) and then remeasure. Prior to and after

conditioning, the dimensions of the tubing shall be in accordance with Table 1 and the longitudinal change

shall be in accordance with Table 3. Dimensions of adhesive thickness shall be taken from specimens which

have been hung vertically in the oven during recovery. The adhesive thickness shall be the average

determined by measuring a cross section taken 1 inch from each end of the suspended specimen. Care should

be taken not to overheat the adhesive so that it drips or flows from the tubing.

Calculate the longitu dinal change as follows:

C = L1 - L0

L0 x 100

Where: C = Longitudinal Change [Percent]

0 = Length Before Conditioning [Inches (mm)]

1 = Length After Conditioning [Inches (mm)]

4.3.2 Tensile Strength and Ultimate Elongation

Determine the tensile strength and ultimate elongation of the tubing in accordance with ASTM D 2671 using

1-inch (25-mm) bench marks, a 1-inch (25-mm) initial jaw separation, an d jaw separation speed of 20 ± 2

inches (500 ± 50 mm) per minute.

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 defects and resubmitted for acceptance. Before resubmitting, full particulars concerning previous

rejection and action taken to correct the defects shall be furnished to th e inspector.

5. PREPARATION FOR DELIVERY

5.1 FORM

The tubing shall be supplied in lengths of 48 +1, -0 inches (1220 +25, -0 mm) 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 leg ib ly marked with the size, quantity, manufacturer’s

identification, specification number, and lot number.
