Significance and Function:
1. The test method of this instrument is used to measure the strength of vertical tension test on buttons and clothing, and the buttons and buttons are not pulled off the clothing;
2. The button sewing specifications required by this method should be in accordance with the standards set by the button manufacturer;
3. This test method is used to establish the relevance of different wearing environments and compare different types and brands of buttons;
4. This standard may include hazardous materials, operations and instruments, and the standard does not list all possible safety issues that may arise during use. Therefore, it is the responsibility of the user of this standard to establish relevant safety and health rules and determine appropriate regulations before use;
5. All buttons need to be sewn tightly on the fabric with a chain stitch; 6 According to the test requirements, when the largest button size is greater than 6mm or less than or equal to 6mm, the button must be able to withstand a tensile force of 90N and 50N respectively.
Advantages of the instrument:
1. The handle can be used to raise and fix the position of the test table, making it easy to replace the sample;
2. The horizontal first wheel operation is designed in accordance with ergonomic principles to make the operator more comfortable;
3. The safety design lock makes the operation safer and more reliable;
4. With the special long frame, the extended test range is wider;
5. The lower cloth clamp, matching parts, stable clamping, easy to use;
6. The hidden spring design greatly improves the pin tightening force and ensures the test repeatability;
7. The upper button clamp, equipped with a variety of clamps, is suitable for different button samples;
8. It is the most convenient design and can reduce the damage caused by the sample slipping during the test.
Operation of button tester:
1. Install the clamp, match the buttons to be tested, and lock the test sample to the base
2. Put down the clamp, hold the buttons tightly and pull them upwards. Each set of buttons must be able to withstand at least 17 pounds of tension (i.e. 7.72kg) and must be maintained for 10 seconds without signs of loosening or damage. 20 buttons of each type must be tested at the same time to be qualified. If one of the buttons is loose or damaged, or after replacement, all buttons must be tested again.
