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.

: Fully complies with international standards ISO 83-76 and ISO 148-83 . Core Measurement : Determines impact work ( gost 9454 78 skachat pdf

: The standard refers to other critical GOSTs, including GOST 10708 for pendulum machine requirements and GOST 166 for caliper measurement accuracy. The standard provides a unified method for evaluating

: Impact work is designated by letters indicating the concentrator type and numbers for pendulum energy, depth, and width (e.g., KCUcap K cap C cap U KCVcap K cap C cap V KCTcap K cap C cap T Technical Data & Access Core Measurement : Determines impact work ( :

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

: 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.
