ASTM E384 Vickers Microhardness Testing Services Provided by Eurolab
Standard-Related Information
The ASTM E384 Vickers Microhardness Testing service is a laboratory testing procedure that determines the hardness of materials using the Vickers method. This method involves applying a load to a square-based pyramidal indenter, which creates an indentation on the surface of the material. The size and shape of the indentation are then measured to determine the hardness of the material.
The relevant standards for this testing service include:
ASTM E384: Standard Test Method for Knoop and Vickers Hardness of MaterialsISO 6507-1: Metallic materials Microhardness Part 1: Test method (Knoop, Vickers)EN 14557: Metallic coatings Determination of micro-hardness (Vickers hardness test)These standards govern the requirements for testing equipment, sample preparation, testing parameters, and data analysis.
