DIN EN 1789 Ambulance Crashworthiness Impact Test
The DIN EN 1789 specifies a standardized procedure for evaluating the crashworthiness of ambulances. This test assesses how well an ambulance can protect its occupants in the event of a collision, ensuring they remain safe and secure during transportation to medical facilities.
The test is crucial for compliance with international safety standards and regulations that govern the design and performance of emergency vehicles. It ensures that ambulances are equipped with advanced crash protection systems designed to minimize injuries sustained by patients and crew members in an accident.
The DIN EN 1789 impact test involves simulating a collision scenario using a specified crash sled, impacting the ambulance at a predefined speed. The ambulance is subjected to controlled impacts from different angles (frontal, side, rear) to evaluate its structural integrity, occupant protection systems, and overall safety performance.
Accurate and reliable testing is essential for manufacturers to ensure their products meet stringent safety requirements. This test provides valuable insights into potential areas of improvement in ambulance design and helps identify any shortcomings that need addressing before the product reaches market.
Scope and Methodology
| Aspect | Description |
|---|
| Test Parameters: | The test uses a crash sled with a mass of 1,500 kg and impacts the ambulance at a velocity of 20 km/h. The impact is directed towards the driver's side door. |
| Instrumentation: | A combination of accelerometers, force sensors, and cameras are used to capture data during the impact. Data includes acceleration levels, deceleration rates, and structural deformation. |
| Specimen Preparation: | The ambulance is prepared by installing a dummy inside the vehicle to simulate an occupant's presence. The test is conducted with the vehicle fully loaded as it would be in service. |
| Data Collection: | All data collected during the impact is analyzed for compliance with DIN EN 1789 requirements. This includes structural integrity, restraint system performance, and overall occupant protection. |
Why It Matters
The importance of crash testing cannot be overstated in the context of emergency vehicles such as ambulances. These vehicles are not only required to transport patients safely but must also ensure that they can withstand severe impacts without compromising the safety of those inside.
In a real-world scenario, an ambulance may encounter various types of collisions—whether from other vehicles or stationary objects. The DIN EN 1789 test simulates these conditions in a controlled environment to provide accurate data on how well the vehicle performs under stress. This helps manufacturers identify potential design flaws and implement necessary improvements.
The results of this testing play a critical role in maintaining public safety by ensuring that emergency services personnel are not exposed to unnecessary risks when responding to incidents. Reliable crashworthiness tests like DIN EN 1789 contribute significantly to enhancing the overall performance and reliability of ambulances, ultimately saving lives through better protection.

Frequently Asked Questions
What is DIN EN 1789?
DIN EN 1789 is a European standard that specifies the procedure for testing the crashworthiness of ambulances. It ensures that emergency vehicles are designed and constructed to protect occupants during collisions.
Why is this test important?
This test is crucial for ensuring the safety of patients and crew members in ambulances. It helps identify potential design flaws and ensures compliance with international safety standards.
What equipment is used during the test?
The test uses a crash sled, accelerometers, force sensors, and cameras to capture data on the impact. This helps in analyzing the vehicle's structural integrity and performance.
How is the ambulance prepared for testing?
The ambulance is loaded with a dummy to simulate an occupant, and all systems are fully operational as they would be in service. This ensures accurate data collection during the impact.
What aspects of the ambulance are evaluated?
The test evaluates structural integrity, occupant protection systems, restraint performance, and overall safety features. This helps in identifying areas for improvement.
How long does the test take?
The actual impact phase lasts only a few seconds, but preparation and data analysis can extend over several days. The entire process typically takes about two weeks.
What are the consequences of not meeting DIN EN 1789 standards?
Non-compliance can result in product recalls, legal action, and reputational damage. It also increases the risk to patients and crew members during emergencies.
How often should this test be conducted?
The frequency depends on manufacturer guidelines, but it is typically recommended every few years or after major design changes. Regular testing ensures ongoing compliance and safety.
