It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. The hardness number is determined by the load over the surface area of the indentation and not the area normal to the force, and is therefore not pressure.
This is not a good indentation. The electronic file may not be reproduced in any way. The hardness number can e3384 converted into units of pascalsbut ast, not be confused with pressure, which also has units of pascals. The right to access the electronic files of ASTM Standards is for purposes of viewing for individual use only.
Currently some watch companies are improving e84 crystal watch glass by testing the strength using the Vickers hardness test. Vickers hardness numbers are reported as xxxHVyye.
ASTM E – 10e2 Standard Test Method for Knoop and Vickers Hardness of Materials
An indentation left in case-hardened steel after a Vickers hardness test. As a rule of thumb the sample thickness should be kept greater than 2. Are you sure you want to empty the cart? The basic principle, as with all common measures of hardness, is to observe the questioned material’s ability to resist plastic deformation from a standard source.

When doing the hardness tests the minimum distance between indentations and the distance from the indentation to the edge of the specimen must be taken into account to avoid interaction between the work-hardened regions and effects of the edge.
Adtm standard has been approved for use by agencies of the Department of Defense. NOTE 2—While Committee E04 is primarily concerned with metals, the test procedures described are applicable to other materials.
While they are progressively making their watches better, they are also using it as a marketing information for the consumer. Last previous edition approved in as E — 10e2. Content only available by subscription.
