THERMOFIT® ES1000 TUBING

Polyolefin, Semi-Rigid, Adhesive-Lined

1. SCOPE

This specification covers the requirements for a dual wall, electrically insulating, extruded tubing, whose

diameter will reduce to a predetermined size upon application of heat in excess of 135º C (275º F).

2. APPLICABLE DOCUMENTS

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

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

extent specified herein.

2.1 AMERICAN SOCIETY FOR TESTING AND MATERIAL (ASTM)

D 2671 Standard Methods of Testing Heat-Shrinkable Tubing for Electrical Use

(Copies of ASTM publications may be obtained from the American Society for Testing and Materials, 1916

Race Street, Philadelphia, Pennsylvania 19103.)

3. REQUIREMENTS

3.1 DIMENSIONS

The dimensions shall be in accordance with Table 2.

3.2 MATERIALS

The tubing shall consist of two components.

a) The jacket shall be fabricated from a thermally stabilized, modified semi-rigid polyolefin, and shall be

crosslinked by irradiation.

b) The liner shall be a thermoplastic adhesive sealant which melts and flows at the shrink temperature of the

jacket.

The tubing shall be essentially free from flaws, defects, pinholes, bubbles, seams, cracks and inclusions.

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

Page 2 SPECIFICATION RT-1113 REVISION Issue 2

3.3 COLOR

Unless otherwise specified, the jacket shall be clear; the adhesive liner shall be amber.

3.4 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

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

Acceptance tests are those performed on tubing submitted for acceptance under contract. Acceptance tests

shall consist of

Dimensions

Tensile Strength

Ultimate Elongation

Heat Shock

Longitudinal Change

Acceptance tests shall be performed on each lot of tubing or an a skip-lot basis per a statistically justified

control plan determined by Thermofit.

4.2 SAMPLING INSTRUCTIONS

4.2.1 Qualification Test Samples

Qualification test samples shall consist of 50 feet (15 m) of tubing of each size.

Qualification of ES1000-1 qualifies ES1000-1 and ES1000-2

Qualification of ES1000-3 qualifies ES1000-3 and ES1000-4

4.2.2 Acceptance Test Samples

Acceptance test samples shall consist of not less than 16 feet (5 m) 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

4.3.1 Material Properties

Unless otherwise specified, perform tests on specimens which have been recovered by conditioning for 3

minutes in a 175 ± 3º C (347 ± 5º F) oven. Condition the test specimens (and measurement gauges, when

applicable) for 3 hours at 23 ± 3º C (73 ±5º F) and 50 ± 5 percent relative humidity for 3 hours 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.

4.3.1.1 Dimensions and Longitudinal Change

SPECIFICATION RT-1113 REVISION Issue 2 Page 3

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 3 minutes in a 200 ± 5°C

(392 ± 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. Calculate the longitudinal 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)]

4.3.1.2 Tensile Strength and Ultimate Elongation

Perform the tests in accordance with ASTM D 2671, using 1-inch (25-mm) bench marks, 1-inch

(25-mm) initial jaw separation and jaw separation speed of 2 ± 0.2 inches (50 ± 5 mm) per minute. Calculate

the tensile strength based on the wall thickness of the jacket only.

4.3.1.3 Heat Aging

Three samples shall be conditioned for 168 hours in an air circulating oven at 175±3°C. After conditioning,

the specimens shall be cooled to room temperature and bent through 180° over a mandrel selected in

accordance to Table 1. Any side cracking caused by flattening of the specimen on the mandrel shall be

disregarded.

Table 1: Mandrel Sizes

Tube Size "I.D", inches Mandrel, O.D. inches

.047 ≤ ID ≤ .250 .313

.250 ≤ ID ≤ .500 .375

.500 ≤ ID ≤ 2.0 .437

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

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

5. PREPARATION FOR DELIVERY

5.1 FORM

The tubing shall be supplied in lengths in accordance with the applicable drawings.

5.2 PACKAGING

Packaging shall be in accordance with good commercial practice.

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

5.3 MARKING

Each container of tubing shall be permanently and legibly marked with the size, quantity, manufacturer's

identification, part number, and lot number.
