Certified for the areas that need it.
Every Acura computer is designed, tested and certified as one complete unit for hazardous locations. Here is what each mark means, which products carry it, and how to get a copy of a certificate for your audit.
Match the rating to the risk.
Hazardous areas are classified by how often an explosive gas atmosphere can be present. Equipment has to be certified for the area it is installed in. A higher-rated unit can go in a lower-risk area, never the other way around.
What each certification means.
The ratings you will see on our marking plates and data sheets, in plain terms.
Class I, Zone 1
Explosive gas is likely during normal operation, such as near vents, pumps and wellheads. RNK Bastion® is our Zone 1 platform, and is also certified Class I Division 1.
Class I, Zone 2
Gas is not expected in normal operation and only briefly if it occurs. Most rig-floor, plant and panel equipment sits in Zone 2 (EPL Gc), and so does most of our range.
Class I, Division 1 and 2
The class and division system used in the United States and Canada. Division 2 matches Zone 2 conditions, and Division 1 covers both Zone 1 and Zone 0. Most Acura computers are certified Class I Division 2.
ATEX
The EU directive 2014/34/EU for equipment used in potentially explosive atmospheres. Certified units carry the Ex mark with the equipment group, category and temperature class, backed by an EU Declaration of Conformity.
IECEx
The IEC’s international certification scheme, built on the IEC 60079 standards and accepted in many countries outside Europe and North America. Every IECEx certificate of conformity can be checked online.
MIL-STD-810
A U.S. Department of Defense test standard for shock, vibration, drops, temperature and humidity. It shows a unit is rugged, not that it is rated for an explosive atmosphere. RoughBook® is tested to MIL-STD-810 methods.
Certifications by product.
The hazardous-location ratings each platform carries in its certified builds.
Certified as one unit, not a list of parts.
Designed for the zone
We choose the protection method, materials and temperature class for the area before the first prototype is built.
Tested as a complete unit
The enclosure, cooling, boards and I/O are tested together by an accredited lab, so the rating covers the whole unit.
Certified per configuration
Custom I/O and integrated boards are engineered into the certified design. Certificates are issued for the configuration you buy.
Traced by serial number
Every unit is serialized and its bill of materials kept on file, so its certificates can be traced for the life of the unit.
Request a product certificate.
Tell us the product and, if you have it, the serial number. We will email the certificates and declarations that apply to your unit.
Have the serial number?
It is on the marking plate, next to the certification marks. With it we send the exact certificates for your unit’s configuration. Without it we send the certificates for the standard build.

Common questions.
Can a Zone 2 unit be installed in Zone 1?
No. Equipment has to be certified for the zone it is installed in. A Zone 1 unit can be used in Zone 2, but a Zone 2 unit cannot be used in Zone 1.
Is Class I Division 2 the same as Zone 2?
They describe similar conditions under two different systems. Division 2 belongs to the North American class and division system, while Zone 2 comes from the IEC zone system that ATEX and IECEx also use. Check which system your site uses before you specify a unit.
Does a custom configuration keep its certification?
Yes, when we build it. Custom I/O, integrated boards and cooling options are engineered into the certified design before the unit ships. Changes made in the field can void the rating.
Is MIL-STD-810 a hazardous-location certification?
No. MIL-STD-810 is a test standard for shock, vibration, temperature and other environmental conditions. It shows a unit is rugged, not that it is safe in an explosive atmosphere.
How do I check an IECEx certificate?
IECEx certificates of conformity are listed on the IECEx website. Search by the certificate number shown on the marking plate and on the certificate we send you.
Not sure which rating your site needs? Send us the area classification and we will tell you what to install.
