The test coil is hung high enough that the material combination can be easily unwound by hand.
A. 2 testing
Line raskatyvaete of the test-coil should lie in the same horizontal plane as the axis of the roll. Stub end material combined must be located in a position corresponding to 12 hours on a clock face. Winding the combined material to a position corresponding to 3 or 9 hours on the dial (depending on which way spend the unwinding of the film roll) and let go of the material combined.
If the material is combined spontaneously unwound to a position corresponding to 6 h, the coil is characterized by the degree of raskatyvaete A.
If the material is combined spontaneously unwound, unwound the free end of the material combined for one full revolution to a position corresponding to 3 or 9 h on the dial and let it go. In this case, if the material is combined spontaneously unwound to a position corresponding to 6 h, the coil is characterized by the degree of raskatyvaete V.

Measuring with a scale division of 1 mm according to GOST 427.
2 preparations for the testing
In order to efficiently approximate the technological control of the manufacturing process allowed the sampling of the combined material after its manufacture.
For the sampling sheet material combined with roll off at least three top coils and cut sheet across the entire width of the roll and a length not less than 700 mm.
On the selected sheet of material combined with a device for cutting samples cut three samples in the form of strips with a width of (15,0±0,2) mm and length (150±5) mm in the longitudinal and transverse directions at a distance of not less than 50 mm from edges for each pair of layers of material combined.
On the same sample allowed to measure the delamination force for only one pair of layers.
Samples having damaging the edges in the form of burrs, tears, trials are not allowed.
Sample for test is divided into sections:
1 — phase pre-delamination — (30±5) mm;
2 — outside area — not less than 50 mm;
3 — the working area — (50±5) mm;
4 — proslavery area — 15−20 mm.
Phase 1 pre-split manually. To facilitate the delamination of the end of the sample not more than 10 mm is immersed in a solvent that weakens the bond strength between the layers, while phase 2 should not be wet. If the sample cannot be stratified, the test is not carried out, and as a result of the test record: «the Material does not separate».
To prevent stretching of the elastic layer of the sample before the test, allowed him to reinforce on the outer surface of the elastic layer of the sample to stick a band-aid or any tape.
G. 3 testing
Initially set distance between the clamps of the tensile machine, is equal to (50±5) mm.
Sample fixed in the clamps of the tensile machine as follows: a fixed clamp layer with less elongation, of the movable layer with high elongation.
During the test, the sample is split until the end of the third area define at least five values of load on the readings of the recording instrument, read in the splitting of the working area. When delamination outside of the plot to observe the values of the load, as they can be unstable as the result of exposure of the sample in the solvent. The values of the load when the delamination outside of the site do not take into account.
In the process of testing proslavery recommend the site to support the tweezers so that the angle between the stratified and prosloennaya parts of the sample was 90 degrees.
If the testing process is breakage of one of the layers of the sample, it is necessary to re-test for newly prepared samples. If repeated trials, again there is a cliff, record the load at which breakage of the sample. The sample shall be deemed satisfactory.
The delamination resistance of the material combined X, N/m, is calculated by the formula
where R is the average value of the delamination load, N;
In — sample width, m.
The average load value of delamination is determined by the results of six parallel measurements.
Test results of a combined material obtained by testing samples taken immediately after its production, are used to approximate process control. Final testing of such material is conducted upon expiration of the conditioning installed by the manufacturer.
