ISO 8124 ASTM D7142-2/F963 EN 71 Button Strength Tester Clothing Buttons Fixing Strength Test Machine

Introduction

It consists of an concave clawless pliers, a bottom fabric plier and an Imada push-pull force meter. The button component is fixed by the concave five-claw pliers, and the clothing is fixed by the bottom fabric plier. By rotating the upper speed control wheel, the user can apply a fixed force and record the fixed force or the breaking force. With the clamps and accessories, this instrument can also test other buttons, denim buttons, four-hole buttons, and clothing accessories such as zippers, bow ties, decals, hooks, D-rings, etc.

Relevant standards:

ASTM D7142-2/F963,16 CFR 1500,EN 71 PART 1,GB 6675,ISO 8124,M&P P115A

Scope of application

Test the fixing strength of buttons, buttons and various clothing accessories. The feature is applicable in the design and manufacturing projects of infant and children's clothing. For example, if a button detaches from the clothing, it may pose a risk of causing the infant to swallow and suffocate. This test item can limit the liability of the clothing manufacturer and ensure that buttons, buttons and other accessories can be properly fixed on the clothing.

Testing method

The fabric with snap fasteners should be placed on the bottom fabric clamp, and ensure that the fabric is compressed after pulling down the push rod. Then, use the concave five-prong button clamp to clamp the button, apply a vertical force of 17 pounds (approximately 7.73 kilograms) and wait for 10 seconds before releasing. If the snap can complete the entire test without being torn off, this snap will be considered safe. At least 20 snaps should be tested each time, and both the concave and convex parts of the snap need to undergo strength testing.

Instrument features

1. Ensures vertical alignment of the pulling force;

2. Fixes the edge of the button without affecting its adhesion;

3. Applies a consistent force continuously for 10 seconds;

4. Can raise and fix the position of the test table through the handle, facilitating sample replacement;

5. Lateral first operation, designed in accordance with ergonomic principles, making the operator more comfortable;

6. Safe design with a lock mechanism, making operation safer and more reliable;

7. Combined with a long-standing frame, it can extend the testing range further;

8. Concealed spring design significantly enhances the tightening force and ensures test repeatability;

9. Reduces damage to the sample caused by slipping and slippage during testing;

10. Simple design, with precise test results.
