I understand that you recommended the crosshead speed of 35 mm/min to measure the retentive force of these 3 magnetic attachments in conclusion part. How did you conclude it? I wonder if the value of 35 mm/min is too close to the minimum crosshead speed that influences the retentive force value of the Nd-Fe-B magnetic attachments.

In this study, there was no significant difference in measured values obtained at crosshead speeds of 0.5 – 50 mm/min. Additionally, regression analysis demonstrated that crosshead speeds of up to 35 mm/min had no impact at all on the retentive force values measured.
The conclusion is that; using the retentive force measuring device specified in ISO 13017:2020; it is possible to measure the retentive forces of magnets and magnetic attachments accurately at crosshead speed of up to 35 mm/min and not at 35 mm/min only.
In order to clarify the concept, I revise the manuscript as follows.

Original:
Using the retentive force measuring device specified in ISO 13017:2020, it is possible to measure retentive forces of magnets and magnetic attachments accurately at crosshead speed of 35 mm/min.

Revised:
Using the retentive force measuring device specified in ISO 13017:2020; it is possible to measure retentive forces of magnets and magnetic attachments accurately at crosshead speed of up to 35 mm/min.

Thank you for explaining in detail. I fully understood what you mean.
