Question

Which of the following is not a hardness testing method?

(a) Rockwell hardness

(b) Brinell hardness

(c) Set method hardness

(d) Shore scleroscope hardness

The question was posed to me during an interview for a job.

My question is from Aircraft Materials in division Testing Aircraft Materials of Aerospace Materials & Processes

Answer 1

The correct answer is (c) Set method hardness

For explanation I would say: Hardness testing methods are processes to check the strength of the material. Rockwell hardness, Brinell hardness, Shore scleroscope hardness and Diamond pyramid hardness are typically used hardness tests. The set method is one of the methods used to determine the yield strength of a material.
