Standard Test Method for
Indentation Hardness of Aluminum Alloys by Means of a
Webster Hardness Gage
中文名称：
ASTM B647-10
使用韦氏硬度计测试铝合金压痕硬度的标准试验方法
替代情况：被ASTM B647-10(2016)替代
标准简介：
The Webster hardness tester is portable and therefore useful for in site determination of the hardness of fabricated parts and individual test specimens for production control purposes. It is not as sensitive as Rockwell or Brinell hardness machines.
1. Scope
1.1 This test method covers the determination of indentation hardness of aluminum alloys with a Webster hardness gage, Model B.
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.2.1 Exception—The values given in parentheses are for information only.
Note 1—Two other models, A and B-75, are in use, but are not covered in this test method. Model A does not provide numerical values of hardness and Model B-75 covers only a part of the range of interest for aluminum alloys.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. 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.

3. Terminology
3.1 Definitions—The definitions of terms relating to hardness
testing appearing in Terminology E6 shall be considered
as applying to the terms used in this test method.
4. Significance and Use
4.1 The Webster hardness gage is portable and therefore
useful for in situ determination of the hardness of fabricated
parts and individual test specimens for production control
purposes. It is not as sensitive as Rockwell or Brinell hardness
machines; see 10.2.
4.2 This test method should be used only as cited in
applicable material specifications.
