Raychem RT-555 TUBING
Modified Fluoropolymer, Radiation Crosslinked,
Flexible, Abrasion Resistant, Flame Retardant, Heat Shrinkable
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 220ºC (428ºF).
The tubing is suitable for use in wire harness systems requiring high fluid resistance.

4.2 SAMPLING INSTRUCTIONS
4.2.1 Qualification Test Samples
Qualification test samples shall consist of 50 feet (15 m) of tubing of the size specified. Qualification of any
size within each size range specified below will qualify all sizes in the same range.
Size Ranges
1/16 through 3/4
1” through 2”
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.
4.2 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 specimens (and measurement gauges,
when applicable) shall be conditioned for 3 hours at 23 ± 3ºC (73 ± 5ºF) 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 100 to
200 feet (30 to 60 m) per minute.
4.3.1 Dimensions, Dimensional Recovery, Longitudinal Change and Concentricity
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. Recover these specimens fully by conditioning for 3 minutes in
a 250 ± 5ºC (482± 9ºF) oven. Remove the specimens from the oven, allow to cool to 23 ± 3ºC (73 ± 5ºF) and
re-measure. Calculate longitudinal change as follows:
LC =
L
1
- L
0
L
0
X 100
Where: LC = Longitudinal Change [Percent]
L
0
= Length Before Conditioning [Inches (mm)]
L
1
= Length After Conditioning (Inches (mm)]
Measure the wall thickness of three 6-inch (150-mm) long specimens, as supplied, in accordance with ASTM
D 2671. Calculate concentricity as follows:
C =
M
1
M
2
X 100
Where: C = Concentricity [Percent]
M
1
= Minimum Thickness [Inches (mm)]
M
2
= Maximum Thickness [Inches (mm)]
