EN 60068-2-27 Shock Testing for On-Board Systems
The EN 60068-2-27 standard is a crucial part of the broader series of standards that provide guidelines and methods for environmental testing. Specifically, EN 60068-2-27 addresses shock tests used to assess the ability of on-board systems in military vehicles to withstand mechanical shocks during operation or transport.
The standard specifies the requirements and procedures for conducting random vibration tests with a defined frequency spectrum to simulate real-world shock events. This type of testing is essential for ensuring that components, subassemblies, and entire on-board systems are capable of enduring the dynamic loads they might encounter in various operational scenarios.
Shock testing under EN 60068-2-27 involves exposing the specimen to controlled shock pulses over a specified frequency range. The test setup typically includes a shaker that generates these shock waves, and sensors placed on the specimen to measure its response. The standard defines parameters such as amplitude, duration, and repetition rate of the shock pulses.
The testing process begins with thorough preparation of the specimens. This involves cleaning the components thoroughly, ensuring all fasteners are secure, and calibrating any onboard electronics or systems that will be tested. Once prepared, the specimen is placed on a test fixture designed to replicate real-world conditions as closely as possible. The shaker then delivers shock pulses according to the specified parameters.
During testing, multiple runs may be conducted to ensure consistent results and account for variability in performance. After each run, data from the sensors is collected and analyzed to determine whether the specimen meets the acceptance criteria outlined in EN 60068-2-27.
The acceptance criteria are based on the structural integrity of the components and their ability to function correctly post-test. For example, a component might need to remain connected after a specified number of shock pulses or maintain operational parameters within acceptable limits. Compliance with these criteria ensures that the tested systems can reliably perform their intended functions in harsh environments.
The results of EN 60068-2-27 testing are typically documented in detailed reports, which include test setup details, observed responses, and conclusions regarding compliance or non-compliance with the standard. These reports serve as critical documentation for quality assurance processes and can be used to inform design improvements or regulatory submissions.
By adhering to EN 60068-2-27, manufacturers ensure that their on-board systems meet stringent requirements set by international standards. This not only enhances product reliability but also supports compliance with military specifications and regulations, thereby reducing the risk of system failures in critical operational scenarios.
In summary, EN 60068-2-27 shock testing is an essential step in validating the robustness of on-board systems used in military vehicles. Its rigorous approach to simulating real-world conditions provides valuable insights into potential weaknesses and areas for improvement, ultimately contributing to safer, more reliable equipment.
Benefits
The implementation of EN 60068-2-27 shock testing brings several key benefits to the development and manufacturing processes of on-board systems in military vehicles:

- Compliance Assurance: Adhering to international standards like EN 60068-2-27 helps manufacturers meet regulatory and certification requirements, facilitating easier market entry into various jurisdictions.
- Cost Efficiency: Early identification of issues through testing can prevent costly rework or redesign efforts later in the development process. It also minimizes the risk of field failures leading to expensive repairs or replacements.
- Competitive Advantage: Meeting high-quality standards like EN 60068-2-27 positions a company favorably against competitors, enhancing its reputation and market position.
- Enhanced Reputation: Successful completion of rigorous testing protocols can significantly bolster the image of an organization within the industry and among potential customers.
- Regulatory Compliance: By aligning with international standards, manufacturers ensure they are meeting all relevant regulatory requirements, thus avoiding legal challenges or penalties.
- Data-Driven Decision Making: The detailed test reports provide valuable data that can be used to make informed decisions about design improvements and future product development.
Industry Applications
The application of EN 60068-2-27 shock testing extends across various sectors within the military industry. From armored personnel carriers to unmanned aerial vehicles, on-board systems play a vital role in ensuring mission success and crew safety.
In armored vehicles, such as tanks and infantry fighting vehicles (IFVs), EN 60068-2-27 ensures that electronic systems, communication devices, and weapon control mechanisms are robust enough to withstand the intense shock environments encountered during combat. The testing process helps identify potential points of failure in these critical components, allowing for targeted improvements.
For UAVs and other unmanned systems, the ability to operate reliably under extreme conditions is paramount. Shock testing ensures that onboard navigation systems, communication links, and power distribution units can function without disruption even after exposure to significant mechanical shocks. This enhances the overall performance and reliability of these advanced platforms.
In addition to military vehicles, EN 60068-2-27 shock testing is applicable in the design and development of on-board systems for naval vessels, air defense systems, and various other military applications where robustness against mechanical shocks is essential. The standard’s comprehensive approach ensures that all components meet stringent performance criteria, contributing to overall system reliability.
The benefits of EN 60068-2-27 are particularly evident in high-stakes environments such as combat zones or hostile terrains where equipment failure could have severe consequences. By incorporating this testing protocol into the development process, manufacturers can significantly improve the durability and operational capabilities of on-board systems, thereby enhancing overall mission success rates.
Customer Impact and Satisfaction
The impact of EN 60068-2-27 shock testing extends beyond internal processes; it directly influences customer satisfaction by ensuring product quality meets or exceeds expectations. Customers in the military sector, particularly quality managers, compliance officers, R&D engineers, and procurement specialists, place a high value on reliability and performance.
By implementing EN 60068-2-27 shock testing, manufacturers can demonstrate their commitment to delivering products that are not only compliant with international standards but also proven capable of performing reliably under harsh conditions. This aligns with the expectations set by military specifications and regulations, thereby fostering trust between suppliers and customers.
The detailed test reports generated from EN 60068-2-27 shock testing provide transparency into the quality assurance processes, offering evidence that the products meet stringent performance criteria. This level of assurance can lead to higher customer satisfaction by reducing concerns about potential failures or substandard components.
