Anti-abrasion performance of the non-stick coating is tested with 3M 7447 scouring pads which is attached to a testing machine that wipes for 3000 - 5000 cycles.

Bottom concavity should be within a low value in 10 repeated tests. We measure the value with a dilatometer when the cookware is cooled down from 200℃ to 20℃ after a thermal shock.

To test the heat-resistant performance of the non-stick coating, we put the pan or pot into the thermotank and heat to 250℃.

Anti-corrosive performance of the non-stick coating is tested with 5% NaCl. The solution is heated for 7 hours.

We put the pan or pot into the dishwasher for 50 washes (45 minutes each time) to ensure it's dishwasher-safe.
