Independent testing centre
The centre for
informed
buying decisions
As an independent testing centre, we assess products against clearly defined, transparent criteria under real-world conditions. Every test result is publicly documented.
Verify a seal
Check a licence number
Every test seal carries its own licence number. Enter it and you go straight to the full test report — with the overall grade, all ten test parameters individually and the test period.
Where to look Where do I find the licence number?
The licence number is at the bottom of the seal, directly above the web address. Is it missing, or does it lead to a different product? Please get in touch.
The scoring key applies across all categories and stays the same for every test. The individual results are fully documented in the test report.
To the testing procedurePM testing procedure
Quality testing to the PM test standard
Not every criterion carries the same weight. The PM testing procedure distributes 300 points across ten test parameters in three evaluation areas. The weighting reflects how strongly a feature determines a product’s fitness for use.
- Product-specific properties 100 of 300 points Quality & workmanship · Design · Size & weight 0%
- Use and safety 120 of 300 points Functionality · Handling & suitability · Safety 0%
- Opinion and service 80 of 300 points Advertising claims · Consumer opinion · Packaging & labelling · Value for money 0%
Why we test
We build bridges between consumers and sellers
On marketplaces, presentation often decides, not quality. A product test against fixed criteria creates common ground.
Before buying
For consumers
The grade comes at the end, not the beginning. Every test report shows which criteria were tested and how they were factored into the result.
- All test reports freely accessible
- Every test parameter shown individually
- Results can be looked up by licence number
After the test
For manufacturers & sellers

- Independent product test with ten test parameters
- Test seal and evaluation report with their own licence number
