The manual tearing strength tester uses the impact pendulum method to measure the tearing strength of fabrics or clothing fabrics, and can also be used to test the tearing strength performance of protective clothing.
Heavy hammers: A-800g, B-1600g, C-3200g, D- 6400g
.
Test principle: The sample is fixed on the clamp, and an incision is cut into the sample, and the pendulum at the position of resisting the potential energy is released.
When the movable clamp leaves the fixed clamp, the sample is torn along the incision direction, and the fabric is torn to a certain length.
The work done is the tearing force
.
Applicable standards: GB/T3917.
1, ISO13937.
1, ASTMD1424, JIS L1096Section8.

5, MethodD, JISL1018Section8.

1, MethodA 2.
The samples should be equilibrated in the above environment for at least 4 hours before testing; 3.
The samples should not be stacked during debugging
.
Sample preparation: 1.
Take 5 samples each in the warp (length direction) and weft (width direction), and make each test sample in the same direction not contain the same warp and weft yarns
.
2.
When cutting the sample, if it is a clear color cloth, the yarn on the edge of the sample should be removed, and when placing the sample preparation template, the short side should be parallel to the yarn in the opposite direction to be measured
.
That is: if the warp is to be tested, the short side of the template should be parallel to the weft; if the weft is to be tested, it should be parallel to the warp
.
3.
Sampling should be taken at least 15cm away from the selvedge, and the warp direction should be indicated by "↑" on the cut test sample
.
As a modern technology enterprise integrating R&D, manufacturing, sales, training and service, Standard Group (Hong Kong) Co.
, Ltd.
is committed to delivering more humanized testing instruments to the market.
Testing instruments such as automotive interior materials, environmental climate aging, etc.
, are more acceptable for non-standard customization.
Before purchase, targeted tests can be carried out according to customer requirements to ensure that the purchased instruments are suitable.
