Question 1

Which MIL-STD standard governs reliability testing for electronic and electrical components used in military applications?

Accepted Answer

MIL-STD-883

Answer

MIL-STD-883 establishes test methods and procedures for microelectronic devices used in military and aerospace applications.

Question 2

In IEC 61508, what is the term used to describe the probability that a safety function will be performed on demand?

Accepted Answer

Probability of Failure on Demand (PFD)

Answer

PFD (Probability of Failure on Demand) quantifies the likelihood that a safety function fails when a hazardous demand occurs, used for low-demand mode systems.

Question 3

What ASTM standard is most commonly referenced for tensile strength testing of metallic materials?

Accepted Answer

ASTM E8/E8M

Answer

ASTM E8/E8M is the standard test method for tension testing of metallic materials, defining specimen geometry, testing procedures, and property calculations.

Question 4

Which SAE standard defines the reliability program requirements for development and production of aerospace and defense systems?

Accepted Answer

SAE ARP4754

Answer

SAE ARP4754 provides guidelines for development of civil aircraft and systems, including reliability and safety processes during the design lifecycle.

Question 5

Under ISO 9001:2015, what is the primary purpose of a design validation activity?

Accepted Answer

Ensure the product meets the needs of the intended use

Answer
