Sleeving of special expanded or recovered dimensions may be supplied as specified in the
contract or order.
2.3
Test Requirements
The test requirements shall be as specified in Table 1.
3.
TEST METHODS
3.1
Unless otherwise specified, tests shall be carried out on specimens of sleeving recovered by
conditioning in a fan assisted air circulating oven at 200 ± 5°C for 4 ± 1 minutes and allowed to
cool in air to ambient temperature. No pre-conditioning period is required prior to testing.
Unless otherwise specified, all tests shall be made under standard ambient conditions according
to IEC Publication 212. In cases of dispute the tests shall be carried out at a temperature of
23 ± 2°C and at 50 ± 5% relative humidity.
3.2
Dimensions and Longitudinal Change
The test method shall be as specified in ASTM D2671.
The length and inside diameter of three 150mm long specimens of expanded sleeving shall be
measured. The specimens shall be recovered in a fan assisted air circulating oven 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 thickness shall be
determined.

TEST METHODS (Cont’d)
3.3
Tensile Strength and Ultimate Elongation
The test method shall be as specified in ISO 37.
Five tubular specimens 125mm long shall be tested. Initial jaw separation shall be 50 mm and
rate of jaw separation shall be 100 ± 10mm per minute.
The test shall be carried out at a temperature of 23 ± 2°C
3.4
Secant Modulus
The test method shall be as specified in Method A of ASTM D882.
Five tubular specimens 150mm long shall be tested. Initial jaw separation shall be 100mm and
rate of jaw separation 10 ± 1mm per minute.
The test shall be carried out at a temperature of 23 ± 2°C.
3.5
Specific Gravity
The test method shall be as specified in Method A of ISO 1183.
3.6
Heat Shock
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.
3.7
Heat Ageing
The test method shall be as specified in ISO 188.
Five tensile test specimens prepared as in Clause 3.3 shall be conditioned in a fan assisted air
circulating oven as specified in Table 1. After conditioning the specimens shall be removed
from the oven, allowed to cool naturally to room temperature and tested for Ultimate Elongation
according to clause 3.3.
3.8
Low Temperature Flexibility
The test method shall be as specified in Procedure C of ASTM D2671.
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 60243-1 (Short time test).
