Can test data from different brands or models of specialized testers (e.g., foam hardness testers) be compared?

If all testers strictly adhere to the same international standard (e.g., ASTM D3574) and are properly calibrated, data should theoretically be comparable. However, minor differences in fixtures, software algorithms, or sensor types can introduce slight variances. For strict comparisons, we recommend cross-verification using a common reference material across all devices.
