How to select the right ISO 12944 environment compliant coating powder?
2500 Hours NSS Test LED Street Light Housing
Select the right coating powder based on different environment is very important for your outdoor lighting projects. This job should be finished when you order the outdoor LED light housing fixtures from your supplier. If this step is not doing well, or any misunderstanding, the result may be very serious and you even have to call back the LED outdoor lighting fixtures which you have sold to your customers.
In fact, if you follow the ISO 12944 environment table to define the corrosive environment, it will be much easier. Herein is the table for you.
| ISO 12944 Classification | Corrosion Risk Level | Typical Environments |
| C1 and C2 | Low | Heated buildings/neutral atmosphere
C2 Rural areas, low pollution |
| C3 | Medium | Urban and industrial atmospheres
Moderate sulfur dioxide levels Production areas with high humidity |
| C4 | High | Industrial and coastal
Chemical processing plants |
| C5I | Very High | Industrial areas with high humidity
and aggressive atmospheres |
| C5M | Marine, offshore*, estuaries, coastal
areas with high salinity |
* Corrosion protection in ISO 12944 C5M – Offshore environments is being addressed via a new standard (ISO 20340) dedicated to this environment.
These environments are based on experiments that have measured the rate of metal loss for uncoated steel. The classification of environments applies to structural steel exposed to ambient (less than 120°C [248°F]) conditions.
Why is this ISO standard so important for LED outdoor lighting fixtures?
ISO 12944 Paints & Varnishes – Corrosion protection of steel structures by protective paint systems (parts 1-8) (1998). The ISO 12944 standard is intended to assist engineers and corrosion experts in adopting best practice in corrosion protection of structural steel at new construction.
ISO 12944 is progressively superseding regional standards to become a truly global benchmark in corrosion control.
Selecting specifications that comply with ISO 12944 provides you with:
- Confidence that the corrosion protection you specify will be fit for purpose
- An objective approach to coating selection
- A simplified matrix of coating systems to select from
- A meaningful coating design life
- A universally accepted standard
Understanding your ISO environment can help to tailor specifications, ensuring your coatings are not under or over specified and saving you unnecessary cost for your LED outdoor Lighting project.
