STANDARD 100 by OEKO-TEX®

STANDARD 100 by OEKO-TEX® is an independent testing and certification system for textile raw materials, intermediate and end products at all processing stages. The tests for harmful substances include substances forbidden by law, substances regulated by law, substances known to be harmful (but not yet legally regulated) and parameters for health care.

AQL 1.5

The AQL (Acceptable Quality Level) defines a precisely procedure at which a certain subset of a good is allocated for a sample. This sample is tested according to settled standards and specifications. From the received results, it is possible to draw conclusions about the quality of the goods. The higher the requirements for a product are, the more stricter are the predefined guidelines. The AQL is therefore a statistical method for determining the quality. Medical gloves must be aseptic and must comply with DIN EN 455. An AQL (accepted quality level) of less than 1,5 is to be observed. The gloves are only tested for water resistance.
