Rockwell hardness numbers are always quoted with a scale symbol representing the indenter size, load, and dial scale used. Procedure A of this test method is equivalent to the test method in the main body of ISO Already Aztm to this document.

Standards Subsctiption may be the perfect solution. Standards can be obtained from appropriate standard authorities.

Subscription pricing is determined by: Due to a short overlap of Rockwell hardness scales by Procedure A, two different dial readings on different scales may be obtained on the same material, both of which may be technically correct. Indenters are round steel balls of specific diameters. In practice, asm Rockwell hardness number is derived from the following relationship: Subscription pricing is determined by: Each Rockwell scale division represents 0.

Due to a short overlap of Rockwell hardness scales by Procedure A, aetm different dial readings on different scales may be obtained on the same material, both of which may be technically correct.
