COD Testing Advantages. COD is most suitable for rapid and frequent monitoring of treatment plant efficiency and water quality. This method is more accurate than BOD (with a 5-10% relative standard deviation) and it offers a relatively short analysis time (2-hour digestion time), compared to the 5-day BOD test.

Nowadays, the quality of goods and services is crucially important. Purchasers and users have come to expect high quality standards from suppliers and manufacturers. This is why the quality of the services and products on offer is checked and documented several times over (e.g. in accordance with ISO 9001:2000).
