标准范围
本文件规定了金属材料三种不同试验力范围的维氏硬度试验方法，包括硬金属和其他硬质合金（见表1）、金属涂层和其他无机涂层。本文件中规定了压痕对角线长度在0,020 mm和1,400 mm之间的维氏硬度测试。使用这种方法从较小的压痕确定维氏硬度超出了本文档的范围，因为由于光学测量的限制和尖端几何形状的缺陷，结果将遭受很大的不确定性。本文件中规定的维氏硬度也适用于金属和其他无机涂层，包括铝上的电沉积涂层、自催化涂层、喷涂涂层和阳极涂层。本文件适用于垂直于涂层表面的测量和横截面的测量，前提是涂层的特性（光滑度、厚度等）。）允许准确读取压痕对角线。本文件不适用于垂直于涂层表面测试时厚度小于0,030 mm的涂层。本标准不适用于检测涂层横截面时厚度小于0,100 mm的涂层。ISO 14577-1可用于测定较小压痕的硬度。”规定了定期验证方法，用于用户对使用中的试验机进行例行检查。对于特定的材料和/或产品，存在相关的国际标准。
This document specifies the Vickers hardness test method for the three different ranges of test force for metallic materials, including hard metals and other cemented carbides (see Table 1), metallic coatings and other inorganic coatings.
The Vickers hardness test is specified in this document for lengths of indentation diagonals between 0,020 mm and 1,400 mm. Using this method to determine Vickers hardness from smaller indentations is outside the scope of this document as results would suffer from large uncertainties due to the limitations of optical measurement and imperfections in tip geometry.
The Vickers hardness specified in this document is also applicable for metallic and other inorganic coatings including electrodeposited coatings, autocatalytic coatings, sprayed coatings and anodic coatings on aluminium.
This document is applicable to measurements normal to the coated surface and to measurements on cross-sections, provided that the characteristics of the coating (smoothness, thickness, etc.) permit accurate readings of the diagonal of the indentation.
This document is not applicable for coatings with thickness less than 0,030 mm when testing normal to the coating surface. This standard is not applicable for coatings with thickness less than 0,100 mm when testing a cross-section of the coating. ISO 14577-1 can be used for the determination of hardness from smaller indentations.”
A periodic verification method is specified for routine checking of the testing machine in service by the user.
For specific materials and/or products, relevant International Standards exist.
