วิธีทดสอบซิป
มีหลายวิธีในการประเมินความแข็งแรงของซิป ความแข็งแรงพื้นฐานสามารถกำหนดได้จากผลลัพธ์ของวิธีการตรวจสอบต่อไปนี้ ซึ่งสามารถตัดสินความแข็งแรงโดยรวมที่เหมาะสมสำหรับการใช้งานตามลำดับได้ (อิงตาม JIS-S3015 และ ASTM D2061)
※เงื่อนไขของเครื่องทดสอบแรงดึง ― ความเร็วแรงดึง: 300 มม./นาที ความกว้างของแคลมป์: 25 มม.

Top stop holding strength
The lower part of an engaged zipper is held securely, then the slider pulled to the top is pulled further up.
![c](https://www.ykk.co.th/wp-content/uploads/2024/04/c.jpg)
Bottom stop holding strength
The slider is pulled down to the bottom stop, and each side of the chain is pulled outwards in opposite directions.

Slider tab pull off strength (90 degree)
Tension force is applied to both the pull-tab and the bottom of the body of an assembled slider.
In addition to the 90°angle shown, a 45°angle is also tested.
(Tensile Testing Machine Speed: 100 mm/min)
