The standard provides a unified method for evaluating how metals respond to sudden, high-velocity loads. This is essential for selecting materials for critical infrastructure such as aircraft, pipelines, and pressure vessels where resistance to brittle fracture is paramount.

: The standard refers to other critical GOSTs, including GOST 10708 for pendulum machine requirements and GOST 166 for caliper measurement accuracy. gost 9454 78 skachat pdf

: To test at specific temperatures, samples are conditioned in a thermostat for at least 15 minutes before being tested within 3–5 seconds of removal. The standard provides a unified method for evaluating

: The Official Regulatory Library and Runorm provide official PDF copies for purchase or download. : To test at specific temperatures, samples are

: Rectangular bars are machined with specific "concentrators" (notches) to promote fracture: Type U : U-shaped notch (often for general quality control).

The test is conducted using a (pile driver). A notched specimen is placed on two supports, and a swinging pendulum strikes the side opposite the notch.
