A Word On The ISO Standard
The ISO 22241 Standard covers how DEF should be manufactured, handled and stored. It's the definitive authority when it comes to DEF purity. When you purchase DEF, you should look for the API logo on product packaging. This means it has been blended to the precise ratio and purity as required in the standard.
From there, it's up to you to handle it properly. The greatest potential for contamination occurs during handling and transport. Here at Thunder Creek, we make this easy for you. From the materials we use to how the system is sterilized, we build all our DEF Solutions according to the standard. Most others do not.
