Testing Standards

Our zippers are manufactured to international safety standards for both physical performance and chemical compliance. We are able to test for all types of physical characteristics as well as gas chromatography analysis in-house. As part of our due diligence standard operating procedure, we submit bulk samples to third party accredited laboratories to corroborate our data.

Upon our customers request, we are also happy to test their bulk orders with third party accredited laboratories.

ASTM International

The ​American Society for Testing and Materials body is an international standards organisation that develops and publishes voluntary consensus technical standards for a wide range of materials, products, systems, and services.

ASTM D2061 and ASTM D2062 are the most common standards relating to zippers and are usually employed for the North American market, however other standards include, but are not limited to, ASTM F963, ASTM E1645, ASTM E1613.

Besides ASTM standards for the North American Market, other critical standards such as CPSIA, CCPSA and 16 CFR 1303 are observed when manufacturing our zippers.


STANDARD 100 by OEKO-TEX® has become the best known and most successful label for textiles tested for harmful substances. SLIK has been certified to Product Class I since 2005.

Our zipper tapes and zipper parts are all subjected to the STANDARD 100 by OEKO-TEX® tests.

Incorporated into the STANDARD 100 by OEKO-TEX® is REACH (Registration, Evaluation, Authorisation, and Restriction of Chemical Substances).

We continue to renew our certificate annually and a copy can be obtained by contacting us.

BSI is a multinational business services provider whose principal activity is the production of standards and the supply of standards-related services.

A new zipper standard to replace BS3084 was approved by CEN in December 2015. The new standard BS EN 16732:2015 came into force on 1 June 2016. This standard references other applicable standards that include, but are not limited to, BS EN ISO 5077, BS EN ISO 139, BS EN ISO 105-C06, BS 7907. For more information about the changes, please click here.

Besides the above standards for the UK, other critical standards such as Directive 2005/84/EC, Directive 91/338/EEC and Directive 88/378/EEC are observed when manufacturing our zippers.
