Raychem XFFR Zero Halogen Heat Shrinkable Tubing
1. SCOPE
This specification covers the requirements for one type of low fire hazard, electrically insulating, extruded tubing
whose diameter will reduce to a predetermined size upon the application of heat in excess of 120C. It is suitable for
use with Hot Melt Adhesive Tape S1030 or Flame-Retardant Mastic Tape S1305.
2. REQUIREMENTS
2.1 Composition and Appearance
The tubing shall be fabricated from thermally stabilized, flame-retardant modified polyolefin and shall be irradiation
crosslinked. It shall be homogeneous and essentially free from flaws, defects, pinholes, bubbles, seams, cracks and
inclusions. It shall contain essentially no halogens.
2.2 Color
The tubing color shall be black.
3. PROPERTIES
The tubing shall meet the requirements of Tables 1 and 2.
4. QUALITY ASSURANCE PROVISIONS
4.1 Classification of Tests
4.1.1 Qualification Tests
Qualification tests are those performed on the tubing submitted for qualification as a satisfactory product and shall
consist of all the tests listed in this specification.
4.1 .2 Production Routine Tests
Production routine tests shall be carried out on every batch, unless otherwise specified and shall consist of the
following: dimensions, longitudinal change, tensile strength, ultimate elongation, low temperature flexibility and
flammability.
5. SAMPLING INSTRUCTIONS
5.1 Qualification Test Samples
Qualification test samples shall consist of 45 m (150 feet) of tubing. Qualification of size 15 or 20 qualifies all sizes.
The color shall be black.
5.2 Production Routine Test Samples
Production routine test samples shall consist of a sufficient length to perform all the tests in 4.1.2 selected at random
from each batch. A batch shall consist of all tubing of the same size, from the same production run and offered for
inspection at the same time. Physical property tests performed at this time qualify subsequent tubing lots produced
from the same compound batch.
6. TEST PROCEDURES
Unless otherwise specified the tubing shall be recovered in a forced air circulating oven for 10 minutes at 150 2C.
6.1 Dimensions and Longitudinal Change
The test method shall be as specified in ASTM D 2671.
The length and inside diameter of three 250 mm (10 inch) long specimens of expanded tubing shall be measured. The
specimens shall be recovered and the length and inside diameter of each shall be measured. The longitudinal change
shall be expressed as a percentage of the original length. The minimum and maximum recovered wall thicknesses shall
be determined.
