The drop weight tear strength tester is suitable for measuring the tear strength of fabrics or clothing fabrics by the impact pendulum method (Elmendorf method), and can also be used to test the tear strength performance of protective clothin.
It is an experimental equipment independently developed and produced by our company Shanghai Qiansh.
, Heavy hammer: A-800g, B-1600g, C-3200g, D-6400.
Test principle: The sample is fixed on the clamp, an incision is cut into the sample, and the pendulum at the position of resisting the potential energy is release.
When the movable clamp leaves the fixed clamp, the sample is torn along the incision direction, and the fabric is torn to a certain lengt.
The work done is the tearing forc.
Applicable standards: GB/T3911 Tear properties of fabrics Part 1 Determination of tear strength Tear strength (Elmendorf) JISL1096Section15, MethodD woven fabric tear resistance test Pendulum method JISL1018Section11, MethodA knitted fabric tear resistance test Pendulum method Advantages and features:The company has been engaged in testing instruments for more than ten years, with Strong after-sales service team;Can deal with various problems in a timely and fast manner to relieve customers' worries;Complete spare parts, solve the trouble of long delivery period of ordered spare parts;Provide outsourced maintenance services;Long-term Supply all kinds of common testing instruments;Keep up with the update of industry standards and provide testing instruments that meet the new standards in a timely manne.
Environmental humidity adjustment:The sample humidity adjustment and test should be carried out in an environment with a temperature of 21±1℃ and a relative humidity of 65±2%;The sample should be equilibrated in the above environment for at least 4 hours before testing; 3.
Samples can not be stacked during debuggin.
Sample preparation: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 yarn.
When cutting the sample, if it is a clear color cloth, the yarn on the edge of the sample should be removed, and the short side of the sample preparation template should be placed parallel to the yarn in the opposite direction to be measure.
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 war.
Sampling should be taken at least 15cm away from the selvedge, and the warp direction should be indicated by "↑" on the cut test sampl.
