List of inactivation times (i.e., zero point) against SARS-CoV-2 on Cu-based surfaces (R: rolling without final annealing; R + A: rolling followed by recrystallisation annealing) from the quasi-dry tests using normal saline solution as inoculum medium.
| Sample | Manufacturing cycle | Zero point (min.) |
|---|---|---|
| Cu R | R | 1 |
| Cu R + A | R + A | 3 |
| Cu15Zn | R + A | ≤10 |
| Cu18Ni20Zn | R + A | 10 |
| Polystyrene | – | >10 |
