Zippers were first developed in America in a way called slippery traveler in 1893. However, this first example was not successful in this way. In 1913, a Swedish engineer from the United States made changes to the model and made the zipper more usable. The benefits of the zipper were first seen during the First World War. Zippers worked well in windproof coats worn by soldiers. 1930'lu years came to be used in women's clothing this time, then became an indispensable part of clothing. The first zipper production in our country was in 1952.

Many test methods and measurement standards are applied to determine the characteristics, quality, durability and lifetime of the zipper to be used. The fixing strength of the handle to the slider, the fixing strength of the upper stopper to the side armor (strength of the upper stopper), the fixing strength of the lower stopper to the side armor (lower stop strength), the retainer fixing strength of the detachable zippers, the chain resistance under the transverse forces, the determination of the slider lock resistance.

The physical tests performed in the authorized laboratories are based on various standards issued by local and foreign organizations. Zipper tests are carried out in accordance with the following standards:

• TS EN 16732 Zippers - Specifications
• BS 3084 Slip fasteners (zips) - Specifications
• ASTM D2061 Standard Test Methods for Strength Testing of Zippers
• ASTM D2062 Standard Test Methods for Usability in Zippers

Bone, nylon or metal zippers produced, baby and children products, coats, tracksuits, raincoats, bag pockets, ornamental accessories, bag mouths, pillows and bed linen, bags and suitcases from boots and boots has a wide range of use.

Laboratories have to have appropriate test and measurement devices and trained and experienced staff in order to obtain high quality, fast and reliable results.
