THERMOFIT® RNF-100 TUBING
Polyolefin, Flexible, Heat-Shrinkable
1. SCOPE
This specification covers the requirements for two types of flexible electrical insulating, extruded tubing
whose diameter will reduce to a predetermined size upon the application of heat in excess of 121°C (250°F).
1.1 TYPE 1
Type 1 tubing shall be flame-retardant and shall be black, white, red, yellow, or blue unless otherwise
specified.
1.2 TYPE 2
Type 2 tubing shall not be flame-retardant and shall be clear.
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.
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
(Type 1 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 consist of 50 feet (15 m) of black, white and clear tubing. Qualification of
black and white shall qualify all colors. Clear shall be qualified separately. Qualification of any size within
each size range specified below shall qualify all sizes within that size range.
Range of Sizes
3/64 through 1/4
3/8 through 1
1-1/4 through 5
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
Condition test specimens and measurement gauges at 23 ± 3°C (73 ± 5°F) and ambient relative humidity
prior to all testing, whether before or after heat shrinking. Unless otherwise specified, perform tests on
specimens which have been fully recovered by conditioning for 3 minutes in a 200 ± 5°C (392 ± 9°F) oven.
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 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]
L
0 = Length Before Conditioning [Inches (mm)]
L
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, and 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 the inspector.
5. PREPARATION FOR DELIVERY
5.1 FORM
The tubing shall be supplied on spools or in lengths of 48 +1, -0 inches (1220 +25.4, -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 legibly marked with the size, quantity, manufacturer's
identification, specification number, and lot number.
