How to get OKS certification

1. Testing

The testing of OKS garbage bags (product sizes 17l, 35l, 60l and 110l) is carried out independently and impartially by the accredited testing laboratory of Ugra (STS 0455).

2. Certification

If the test report confirms conformity with the requirements of the OKS directive, you can apply for certification from the Swiss Association of Municipal Infrastructure (SVKI). All information is available in advance on request from the SVKI office.

3. Monitoring

The Ugra testing laboratory (STS 0455) examines twice a year (spring/autumn) the products of the manufacturers brought in the sales. The samples are collected nationwide in the retail trade.
