EN 1621-2 Back Protector Performance Testing
The EN 1621-2 standard provides a framework for testing back protectors used in protective clothing, particularly those intended to be worn by individuals who may be exposed to falls or similar hazards. This test is crucial for ensuring the safety and reliability of such equipment in military applications where personnel often work under hazardous conditions.
Back protectors are designed to absorb impact energy and distribute it across a broader area, thereby reducing the likelihood of injury from impacts. The EN 1621-2 standard specifies the criteria for testing these protective devices to ensure they meet minimum performance requirements in terms of impact resistance and durability.
The test involves subjecting the back protector to a series of drop tests using a specified mass and height, with the goal of simulating real-world scenarios where a person might be subjected to a fall. The results are then analyzed to determine if the protector has met the required performance criteria as defined in the standard.
For quality managers responsible for ensuring that suppliers meet regulatory requirements, this test is essential. Compliance officers and R&D engineers will find it particularly useful when developing new products or certifying existing ones. Additionally, procurement teams can rely on these tests to ensure they are purchasing equipment that meets the necessary safety standards.
Scope and Methodology
| Test Parameter | Description |
|---|---|
| Mass of Drop Weight | The standard specifies a drop weight of 5 kg for the testing procedure. |
| Height from Which to Drop | The height is determined based on the type of protector being tested, ranging from 1.0 m to 2.4 m. |
| Type of Surface | A rigid surface that can withstand the impact without damage or deformation is required. |
| Acceptance Criteria | Description |
|---|---|
| No Visible Damage | The protector must not show any visible signs of damage after the test. |
| Impact Absorption | The protector should absorb at least 75% of the impact energy from the drop test. |
The testing process begins with selecting a representative sample of back protectors. These samples are then prepared according to the standard's specifications, which may include cleaning and conditioning them if necessary. Once prepared, they undergo the drop tests using the specified mass and height from the rigid surface.
After each test, the protector is inspected for any visible damage or deformation. Simultaneously, data on energy absorption is collected using appropriate instrumentation. If a protector passes all criteria, it can be certified as compliant with EN 1621-2, ensuring that it meets the necessary safety standards.
