During the British Standard Test, a standardised scouring pad is moved on the coating under the pressure of 15 Newtons in a washing up liquid solution. This method should simulate the cleaning of cookware. The test ends as soon as the substrate is exposed. Fundamentally: the longer a coating survives the British Standard, the higher its lifespan.
Our GREBLON® C3+ passed the British Standard with over 20,000 double-strokes. This corresponds to a lifespan of around 5 years.
To test the wear-resistance of coatings, it is possible to use various abrasion test methods, e.g. the ATP tiger’s claw test. Three ballpoint pen refills are moved in circles over the coating at a temperature of 200°C. This is the only test at high temperatures which assesses thermoplasticity, adhesion and intercoat adhesion.
Even the GREBLON® C2 manages approx. 45-60 minutes in the tests. In the case of intensive use, this corresponds to a use of over a year.
To simulate everyday use of a pan coating, all GREBLON® coatings go through the specially developed GREBLON® Performance Test. This test combines ten different test procedures which a pan must go through one after another and combines non-stick, corrosion and wear test into one process: the sugar test, the washing up liquid test, the cooking test and the egg test.
All GREBLON® C products for cookware must pass this test.
During this test, the pan is divided into four areas and filled with a special mixture of chrome-steel balls, corundum and water. Then, the pan is shaken in a circle at a spin speed of 300rpm for 45 minutes. After every 15 minutes, the pan is assessed, and the covering removed from another quarter. Then, the non-stick effect is tested by means of a pancake and milk test.
With our GREBLON® C2, our entry-level product already passes this test with an »LGA good«.
Ingredients such as vinegar, salt, tomatoes or cooking on a high heat over a long period of time, or keeping foodstuffs in pots and pans exposes coatings to aggressive substances. Here, there is a risk of corrosion which, among other things, can feature the formation of bubbles to the loosening of the coating. To discover weaknesses in the corrosion protection, we carry out corrosion tests by boiling salt water. The pan is filled with a 10% NaCl solution and assessed after 24 hours of boiling. Afterwards, the pan is heated up with the solution in a 48-hour interval and stored. Then, the pan and solution are stored once more for a period of 10 days.
The complete C series passes this test, which means that after 24 hours, no evidence of corrosion can be identified.
