What is ISO 21612 about ?
ISO 21612 establishes an adequate procedure to determine crosstalk values in order to improve comparability of measurement results between testing laboratories and to enable a load cell performance rating in accordance to the crosstalk specification for transducers in vehicle crash testing given in ISO 6487, SAE‑J211‑1 and SAE J2570.
The crosstalk value helps to check the transducer’s performance and to identify sources of error during the calibration process.
Who is ISO 21612 for ?
ISO 21612 on crosstalk determination for multi-axis load cell is applicable to:
- Vehicle manufacturers
- Vehicle testing laboratories
- Vehicle regulatory authorities
- Multi-axis load cell manufacturers and suppliers
Why should you use ISO 21612 ?
The problem of crosstalk happens when the measurement task involves multiple loads. It is important to handle the issue of crosstalk.
ISO 21612 provides test method, test setup and general preconditions for the test for the crosstalk determination for multi-axis load cell. This will help you to determine crosstalk values in order to improve the comparability of measurement results between testing laboratories and to enable a load cell performance rating in accordance to the crosstalk specification for transducers in vehicle crash testing given in ISO 6487, SAE‑J211‑1 and SAE J2570.
As load in different axes can affect the transverse channels differently, the values of the transverse channels need to be captured for each load case. ISO 21612 gives guidelines to capture the data.
