| Hard Chrome | 0.39 | 0.32 |
Sample Identification
The samples were identified by their coating indication; Steel, Nye-Kote™, Nye-Tef™, Nye-Carb™, Kanigen®, Industrial Hard Chrome.
Test Method
The samples were allowed to condition at standard laboratory conditions of 72 +/- 4F and 50% +/-5% relative huimidity for at least 40 hours prior to testing. Testing was done with according to ASTM D1894. Standards used are detailed below.
| Test Method | Test Method Title | Deviations from Method |
