Add the following new clauses:
51 Dynamic shear at ambient temperature

53 Dynamic shear after heat shock and heat ageing
54 Rolling drum peel to aluminium
55 Aluminium rod dynamic shear
56 Sealing

Add after Clause 50, introduced in Amendment 1, the following new Clauses 51 through 57:
51 Dynamic shear at ambient temperature
51.1 Principle
This test is designed to evaluate the strength of dual wall sleevings under shear conditions
when bonded to an aluminium substrate.
60684-2 Amend. 2 IEC:2005(E) – 3 –
51.2 Apparatus
Aluminium strips (100 ± 5) mm x (25 ± 1) mm x (0,9 ± 0,1) mm.
Degreasing solvent: 2-Butanone (methyl ethyl ketone)
Specimen assembly fixture (see Figure 16)
Silicone release paper
320 grit abrasive
Tensile test machine
Oven (for method 52, dynamic shear at elevated temperature)
Weight and Mass 1,4 kg ± 0,1 kg.
Suitable weight to flatten specimens.
51.3 Form and number of test specimens
Three test specimens shall be prepared. Three strips of aluminium shall be abraded and
degreased on one side on a length of at least 20 mm from one end. Three lengths of sleeving
at least 120 mm long shall be recovered in an oven for the time and temperature as specified
in IEC 60684-3. Immediately after removal the sleeving shall be cut open longitudinally and laid
flat on the silicone release paper, with the inside coated surface in contact with the silicone
paper. A weight of sufficient mass to keep the specimens flat shall be placed on top.
This assembly shall be allowed to cool to room temperature before the weight is removed. Any
other suitable method for flattening the sleeving may be used.
The three specimens of the sleevings shall be finally cut longitudinally (100 ± 5) mm ×
(25 ± 1) mm.
The aluminium strips and cut sleeving specimens shall be assembled as shown in Figure 16,
with the coated surface of the sleeving in contact with the abraded surface of the aluminium,
overlapped between 12,5 mm and 14,2 mm. The weight with mass 1,4 kg shall be
preconditioned in an oven for at least 1 h at the assembly conditioning temperature as
specified in IEC 60684-3. The whole assembly, as shown in Figure 16, shall be placed in an
oven for the time and temperature as specified in IEC 60684-3. The assembly shall then be
removed from the oven and allowed to cool to room temperature before the weight is removed.
51.4 Procedure
Insert the specimen in the tensile test machine by clamping at least 25 mm of the aluminum
strip in the top jaw and at least 25 mm of the sleeving in the bottom jaw. The rate of jaw
separation shall be (50 ± 5) mm/min. Record the maximum load for each specimen.
51.5 Result
The result shall be the mean of the three maximum loads.

52 Dynamic shear at elevated temperature
The test specimens shall be prepared in accordance with 51.3.
The procedure shall be in accordance with 51.4 except that the test is performed in an oven
mounted in the tensile test machine. The test specimens shall be pre-conditioned in the test
oven and at the temperature of test for at least 30 min. The test temperatures shall be as
specified in IEC 60684-3.
53 Dynamic shear after heat shock and heat ageing
The test specimens shall be prepared in accordance with 51.3.
The test specimens shall be sandwiched between two PTFE or PTFE coated aluminium plates
as shown in Figure 17 with the bolts just sufficiently tight enough to ensure the specimens
remain flat during the heat shock or heat ageing periods. The assembly shall be conditioned in
an oven for the time and temperature specified in IEC 60684-3. The test specimen shall be
removed from the oven and allowed to cool to room temperature before they are removed from
the aluminum plates.
The test specimens shall then be tested in accordance with 51.4.
