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. A notched specimen is placed on two supports,

is a critical interstate standard that establishes the methodology for impact bending tests on ferrous and non-ferrous metals . Introduced on January 1, 1979, it defines the procedures for determining the impact strength (toughness) of materials across a broad temperature range, from Standard Overview and Purpose

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