English

Subject field(s)
  • Equipment and Plant (Metallurgy)
  • Metallurgy - General
CONT

Alongside the usual pendulum impact testing machines a variety of testing appliances has been developed for special purposes, especially in the USA, where, in the interests of new technological requirements, whole structural components are subjected to impact loading ...

OBS

pendulum impact test: The pendulum impact test ascertains quickly and simply the total energy required to test a specimen to destruction ...

OBS

pendulum impact testing machine : Term standardized by ISO and BSI.

Key term(s)
  • pendulum impact machine

French

Domaine(s)
  • Équipement et matériels (Métallurgie)
  • Métallurgie générale
DEF

Appareil utilisé pour déterminer la résilience d'un métal ou d'un alliage.

CONT

L'appareil d'essai de résilience des métaux est un mouton-pendule constitué d'une masse tournant autour d'un axe. La masse comporte un couteau destiné à rompre l'éprouvette. L'appareil est équipé d'un système qui permet de mesurer l'énergie absorbée par la rupture de l'éprouvette.

OBS

Le dispositif le plus communément utilisé est le mouton-pendule de Charpy.

Subject field(s)
  • Equipment and Plant (Metallurgy)
  • Metallurgy - General
DEF

An apparatus used to measure brittleness, especially notch brittleness, in which a notched bar or other specimen is broken by the action of a rotating flywheel or by a blow from a monkey (or) tup (dropped weight) or from a pendulum as in the Charpy test, the energy absorbed by the broken specimen being thereupon ascertained ...

OBS

Alongside the usual pendulum impact testing machines a variety of testing appliances has been developed for special purposes(a) Drop Test Machines including the ram impact testing machine(b) An Appliance for Automatic Impact Testing down to temperatures of minus 391 degrees Fahrenheit(c) A Pneumatic Impact Testing Machine(d) A Rocket-Powered Pendulum.

Record 3 2016-02-29

English

Subject field(s)
  • Engineering Tests and Reliability
  • Metallurgy - General
CONT

In the Charpy impact test, a notched specimen is supported as a simple beam and is fractured by a single blow. [The] standard pendulum-type Charpy impact-testing machine [is] used..... The specimen is placed on the anvils in the horizontal position. [The] specimen is broken with a single blow delivered by the pendulum from a raised position, and the energy absorbed is read directly from the scale.

OBS

The general features of [the Izod impact-testing machine] are the same as those for the Charpy impact-testing machine....

French

Domaine(s)
  • Fiabilité, contrôle et essais (Ingénierie)
  • Métallurgie générale
CONT

Un essai de résilience a pour but de déterminer la ténacité d'un métal, c'est-à-dire sa résistance au choc. Celle-ci est mesurée par l'énergie nécessaire pour provoquer la rupture d'un échantillon. On appelle cette énergie de rupture la résilience. [L'appareil] utilisé est le mouton-pendule de Charpy.

Record 4 2011-06-20

English

Subject field(s)
  • Masonry Practice
DEF

A construction work composed of elements containing air voids.

CONT

Impact sound insulation [can be] determined by laboratory testing. A standard "tapping machine" is set to operate on a horizontal steel plate which rests against the test specimen. The sound transmission through the wall is then measured and the impact sound levels are converted to normalised levels using a reference equivalent absorption area of 1. 0 m². Adequate impact sound insulation is achieved if the performance of the test specimen is equivalent to, or better than, the performance of a cavity brick construction under the same test conditions.

French

Domaine(s)
  • Maçonnerie
OBS

corps creux : matériau de maçonnerie moulé comportant une proportion importante de vides d'air : blocs, briques creuses, et surtout hourdis creux pour entrevous de planchers.
