Understanding LD & HRC Values on Harness Tester Display

Start date Sep 10, 2016

In summary, LD and HRC values on a harness tester display represent the force and pressure that a harness can withstand before stretching or breaking. These values are measured by applying controlled force and determining the resulting deflection or release. A higher LD value indicates a stronger harness, while a higher HRC value indicates a secure hold. These values can change over time due to wear and tear, so regular testing is important for safety. Low LD and HRC values can compromise the effectiveness and safety of a harness, making it crucial to monitor and understand these values.

FAQ: Understanding LD & HRC Values on Harness Tester Display

What do LD and HRC values represent on a harness tester display?

LD stands for "Load Deflection" and HRC stands for "Holding and Release Capacity". These values indicate the amount of force and pressure that the harness can withstand before it begins to stretch or break.

How are LD and HRC values measured on a harness tester?

The harness tester applies a controlled amount of force to the harness and measures the resulting deflection or stretching. The HRC value is then determined by applying a higher force until the harness releases or breaks.

What is considered a "good" LD or HRC value for a harness?

This can vary depending on the type of harness and its intended use. However, in general, a higher LD value indicates a stronger and more durable harness, while a higher HRC value indicates a secure and reliable hold.

Can LD and HRC values change over time?

Yes, LD and HRC values can change as a harness is used and undergoes wear and tear. It is important to regularly test and monitor these values to ensure the safety and effectiveness of the harness.

How do LD and HRC values affect the safety of a harness?

LD and HRC values are important indicators of a harness's strength and ability to hold and release a load. A harness with low LD and HRC values may not be able to withstand the necessary forces and could lead to accidents or injuries. It is crucial to understand and monitor these values to ensure the safety of anyone using the harness.
