The first button samples in history were found in the Near East in 2000 BC. They are made using animal bones, seashells or wood. Later, samples of buttons were found in the Bronze Age. Loops were also used in ancient Egypt, with one end of the garment tied through the hole in the second piece. The buttons have developed over time and become an integral part of the garments.

Testing the impact resistance of knobs used by textile manufacturers against impacts is an important issue in terms of product durability and quality. It is one of the most important safety tests against the risk of children swallowing buttons, especially in children's clothing.

The basic test for determining the strength of the button is the push and pull strength tests. Many test devices have been produced for these tests. What they all have in common is that buttons and similar accessories used in garments are designed to measure the tensile strength. In these devices, the breaking strength of the buttons is measured with the help of different jaws. These devices can be used to measure various weights, as well as the breaking distance of buttons and similar accessories.

The physical tests performed in the authorized laboratories are based on various standards issued by domestic and foreign organizations. Tests for buttons and similar accessories are carried out in accordance with the following standards:

• BS 4162 Test methods for buttons
• ASTM PS 79 Temporary test method of holding properties of fork-ring ring-attached components
• ASTM D4846 Standard test method for opening resistance of fasteners

These laboratories are required to use state-of-the-art equipment and equipment in order to obtain quality, reliable and fast results. In addition to this, having a strong technological infrastructure and an experienced and trained staff increases the competitiveness of laboratories.

In the textile sector, it is important to undergo physical testing of not only woven fabrics but also all kinds of auxiliary materials. With this measurement and test studies, the usability of the products has been analyzed within the internationally accepted standards and tolerances.
