Standard Test Method for

Indentation Hardness of Aluminum Alloys by Means of a 

Webster Hardness Gage

中文名稱：

ASTM B647-10 

使用韋氏硬度計測試鋁合金壓痕硬度的標(biāo)準(zhǔn)試驗方法

替代情況：被ASTM B647-10(2016)替代

標(biāo)準(zhǔn)簡介：

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.
