TEST METHODS (Cont’d)
3.8
Low Temperature Flexibility
The test method shall be as specified in Procedure C of ASTM D2671.
For sleeving of recovered bore 6mm or less, apply the test to whole sections of recovered
sleeving. For sleeving of recovered bore greater than 6mm, apply the test to strips 6mm wide,
cut from the recovered sleeving, with their lengths parallel to the extruded axis.
Mandrel diameter shall be 15 x specimen thickness ± 10%. For tubular specimens the thickness
is the outside diameter.
The specimens and mandrel shall be conditioned as specified in Table 1.
3.9
Flammability
The test method shall be as specified in ASTM D876.
3.10
Electric Strength
The test method shall be as specified in IEC 243 (Short time test).
3.11
Copper Contact Corrosion
The test method shall be as specified in ASTM D2671.
The specimens shall be conditioned in a fan assisted air circulating oven as specified in
Table 1, allowed to cool naturally to room temperature and tested for Ultimate Elongation
according to Clause 3.3.
3.12
Copper Mirror Corrosion
The test method shall be as specified in ASTM D2671.
The specimens shall be conditioned as specified in Table 1.
3.13
Water Absorption
The test method shall be as specified in Method 1 of ISO 62.
For sleeving of recovered bore greater than 8mm, three disc specimens of diameter 25 ± 1mm
shall be cut from the sleeving. For sleeving of recovered bore less than or equal to 8mm, three
tubular specimens 50mm long shall be cut from the sleeving.
3.14
Fluid Resistance
The test method shall be as specified in ISO 1817.
Five tensile test specimens prepared as in Clause 3.3. shall be completely immersed in each of
the fluids for the times and temperatures specified in Table 1. The volume of the fluid shall not
be less than 20 times that of the specimen. After immersion, lightly wipe the specimens and
allow to air dry at 23 ± 2°C for 1h ± 15m. The Tensile Strength and Ultimate Elongation of
each specimen shall be tested according to Clause 3.3. The test shall be repeated on the
remaining specified fluids.

TEST METHODS (Cont’d)
3.15
Fungus Resistance
The test method shall be as specified in ISO 846.
The specimens shall be conditioned for 56 days, and tested for Tensile Strength and Ultimate
Elongation according to Clause 3.3.

5.
SAMPLING
Tests shall be carried out on a sample taken at random from each batch of finished sleeving.
A batch of sleeving is defined as that quantity of sleeving extruded at any one time.
Testing frequency shall be Production Routine, 10th Batch or Qualification. Production Routine
tests consisting of Visual Examination, Dimensions and Longitudinal Change shall be carried
out on every batch of sleeving. 10th batch tests shall consist of Tensile Strength, Ultimate
Elongation, Secant Modulus at 2% Strain and Specific Gravity.
Qualification tests shall be carried out to the requirements of the Design Authority.
6.
PACKAGING
Packaging shall be in accordance with good commercial practice. Each package shall bear an
identification label showing material quantity, description, size, colour and batch number.
Additional information shall be supplied as specified in the contract or order.
