ASTM F428-03a

Заменен
Standard Test Method for Intensity of Scratches on Aerospace Glass Enclosures — 4 стр.
Значение и использование

Scratches exist on all glass surfaces. Often there are very fine scratches from cleaning operations that are not visible when looking through the glass. Visible scratches may be distracting to the observer looking through the enclosure. Therefore, a procedure to define scratches is useful. A visual standard is used because it is not practical to measure the dimensions of the fine scratches in the scope of this test method.

Область применения
