میانگین و کوواریانس نمونه
میانگین نمونه (Smple mean, sample average) یا میانگین تجربی (Empirical mean, Empirical average) و کوواریانس نمونه (sample covariance) یا کوواریانس تجربی (empirical covariance) آماری هستند که از نمونه‌گیری از داده‌ها بر روی یک یا چند متغیر تصادفی محاسبه می‌شوند.
Unpacking ASTM A967
ASTM A967 defines seven tests for verification that a suitable passive surface has been formed on the component surface. These tests are all qualitative. Although some tests can more precisely detect the amount of free iron remaining on a surface, they are meant to serve as a go, no-go test for passivation. Water immersion test.
