Conformance Testing is Essential to Ensure Your Software Complies with Industry Automotive Standards and Regulations
Building on over 30 years of automotive experience, we have developed unique test processes that go beyond standard specifications. Since 2010, our test house in Germany is accredited by DAkkS according to DIN EN ISO/IEC 17025. Our processes deliver exceptional results and have earned us a trusted status with most Car Makers worldwide.
Based on our active participation in different working groups (ISO, TC8, etc.), and offering test labs in Rheinmünster, Germany, Detroit, USA, and Shanghai, China, we can offer a wide range of different conformance tests according to all common LIN, CAN/CAN-FD and OA Ethernet standards.
We don’t just test your device, we can also help you solve problems discovered during testing. We provide an explanation of each test case issue and how to address it. Our engineering experts can also review your code and suggest potential changes, upon request.
In addition to conformance testing we also perform:
- Performance Tests
- Stress Tests
- Interoperability Tests
- Application Specific Tests
- Endurance Tests
- Climate Chamber Tests
- Customer Specific Tests
We will help to ensure functionality and robustness for your application by testing on ECU level as early as possible in the development phase. Request a quote today for the type of testing you require.

Commonly requested and supported Test Standards: ISO 16845, GMW 14241, GMW 3110, GMW 17106
Our typical lead times are 5 weeks or less.
Ethernet Testing
Ethernet is the most recent automotive industry introduction. We continue maintaining current standards and are an active participant in the Automotive Ethernet community. This allows us to stay current with the changes and introduce these into our Conformance testing process.
Commonly requested and Supported Test Standards: TC8 (Layers 1 & 3-7) (100BASE-T1, 1000BASE-T1)
Our typical lead times are 5 weeks or less.
Please contact us if you are looking for conformance tests that are not listed on this website.
We also offer a wide range of LIN and CAN tests based on OEM requirements.
If you do not have any specifications or requirements but would like to test your product, we will support you in creating a customized test plan just for you.
Furthermore, we offer test support during development, support in error analysis and error elimination.
Testing Types

LIN (Local Interconnect network) is a serial network protocol used for communication between components in vehicles. IHR GmbH is the leading force to migrate LIN specification into an ISO standard. Our testing practices go beyond standard specifications and provide consistent high-quality results.
IHR GmbH offers tests of your ECUs and semiconductors according to common LIN standards 1.3, 2.0, 2.1, 2.2/2.2A and ISO17987
The SAE J2602-2 protocol of SAE (Society of Automotive Engineers) was developed based on the LIN 2.x protocol.
IHR GmbH offers conformance tests according to the test specification SAE J2602-2, including additional GMW specific options.
With IHR GmbH you can either order a complete test, including data link layer and physical layer, or a partial test, such as transceiver only.
Based on the specification SAE J2602-2, we also provide additional tests with detailed information on stability and robustness of your application. Most of these tests are OEM specific, such as sleep/wake cycle stress test and transceiver management.
CAN (Controller Area Network) was internationally standardized and is defined in the specification ISO 11898 with layer 1 (physical layer) and layer 2 (data link layer). Most of the applications assume ISO 11898-2 (High Speed-CAN) and ISO 11898-3 (Low Speed-CAN) for the physical layers. Test specifications are based on these standards and are designed to meet conformance requirements.
IHR GmbH offers testing according to ISO 11898 and ISO 16845.
CAN-FD is being seen as the flexible alternative to CAN. Over the years, the complexity and number of CAN bus systems have increased steadily. To cope with these demands, like high bus load and selective wake-up, the classical CAN bus migrated to a CAN-FD bus with flexible data rates, also allowing for higher transmission rates.
IHR GmbH offers testing according to ISO 11898 and ISO 16845.
GMLAN (General Motor’s Local area network) is an application and transport layer protocol, based on the classic CAN format.
We offer testing in high-speed mode, mid-speed mode or low-speed mode, depending on the test device (control unit) and according to GM specification GM 14241.
We offer complete automated diagnostic testing according to GM specification GM W3110.
We offer conformance tests for ECU according to CG2474, which is the leading specification for components and diagnostics in the GM group. This conformance test is a mandatory demand for all ECUs to fulfill the GGSE ECU Diagnostic Infrastructure Requirements.
Automotive Ethernet Testing
As consumer demand for in-vehicle connectivity and advanced driver assistance (ADAS) continues to grow, the automotive industry is under constant pressure to deliver competitive, innovative features while minimizing cost. Automotive Ethernet technology allows multiple in-vehicle systems to simultaneously access information over a single unshielded twisted pair cable. With IHR GmbH as an active member in the working groups TC8, we offer a full range of corresponding tests to support that.
OPEN Alliance TC8: Automotive Ethernet ECU Test Specification
- Layer 1: Physical Layer OPEN Alliance BroadR-ReachTM (OABR)
- Layer 3: Network Layer, IP, ICMP
- Layer 4: Transport Layer, UDP, TCP, DHCP
- Layer 5-7: Application Layer, SOME/IP, SD
Note: BroadR-Reach™ is a trademark of Broadcom Limited in the U.S. and/or other countries.
PSI5 (Peripheral Interface 5) is a common interface that connects external sensors in the car with the ECU.
IHR GmbH is the co-editor of the test specification V1.3 as part of the PSI5 working group. The test specification V2.0 was actually defined under the leadership of IHR GmbH.
