The Rockwell hardness tester is a direct reading instrument which operates on the principle of differential depth measurement. It consists essentially of a series of levers which give the proper mechanical advantages to a small weight, a platform for support of the specimen, a direct reading hardness dial and a shank for holding the penetrators.  1, record 1, English, - Rockwell%20hardness%20tester

Méthode de Rockwell. [...] C'est une machine à levier [...] mais dans cette machine, on mesure l'enfoncement du pénétrateur à l'aide d'un comparateur à miroir dont le spot lumineux se déplace sur une échelle graduée transparente E. Un graphique joint à l'appareil donne directement [la dureté et la résistance à la rupture] en fonction de la profondeur de pénétration.  2, record 1, French, - machine%20Rockwell

Plastics and related plastic insulating materials may be measured by an indentation hardness tester. Results give an indication of the extent of cure of some thermosetting materials at room temperature, and act as a control test to indicate the punching quality of laminated plastics at the processing temperature. Indentation hardness numbers relate to the area or depth of indentation made by an indenter of fixed geometry under a known static load.  4, record 2, English, - durometer

La dureté d'un matériau, et plus particulièrement des métaux, est déterminée par la résistance qu'ils opposent à la pénétration d'un poinçon de forme donnée, soumis à une force connue pendant un temps donné; on mesure, ensuite, les dimensions de l'empreinte permanente laissée par le poinçon. Les appareils utilisés pour ces mesures sont appelés duromètres [...]  3, record 2, French, - durom%C3%A8tre

The Tukon tester... was designed primarily to make possible hardness testing, using extremely shallow indentations. This permits(a) testing of extremely small dimensional pieces,(b) determination of hardness gradients in superficially hardened surfaces,(c) exploring hardness variations over small areas, and(d) the determination of the hardness of metal constituents. The latter type of testing, as applied to determinations involving various components of microstructure, is referred to as micro-hardness.  1, record 3, English, - micro%2Dhardness%20testing

for "micro-indentation testing" : In the broad sense the term micro-indentation is more appropriate than micro-hardness, because this type of testing utilizes minute indentations, whereas the hardness values are not necessarily small.  1, record 3, English, - micro%2Dhardness%20testing

Du point de vue scientifique, on peut séparer les essais de dureté [...] des essais de microdureté, par le fait que les premiers intéressent un nombre quelquefois très important de grains de métal, alors que les seconds sont destinés en principe à définir les propriétés à l'intérieur des grains soit de la matrice, soit de ses divers constituants.  2, record 3, French, - essai%20de%20microduret%C3%A9

Airport Equipment AB has announced that it is marketing a new system, the Laser RST(Runway Surface Tester). The device is designed to be mounted in a vehicle which drives down the runway or taxiway at between 18 and 55 mi/h and accumulates digitised information about the state of the surface. The equipment measures hardness, transverse section and depth and spacing of ruts.  1, record 4, English, - runway%20surface%20tester

Very recently a new ultrasonic hardness testing device..., called the Sonodur has appeared on the market. This device, which is an indentation type microhardness tester with an electronic readout, employs the use of a diamond tipped magnetostrictive rod which is electrically excited to its resonant frequency.  1, record 5, English, - microhardness%20tester

Dans certains cas (aciers spécialement traités pour outils), il est intéressant de connaître la dureté «point par point»; or, les méthodes précédentes, [méthodes Brinell, Rockwell et Vickers] en raison même de leur principe et de la dimension des poinçons, ne donnent de la dureté qu'une indication macroscopique [...] Pour étudier de façon continue la dureté d'un échantillon, on a recours à des appareils spéciaux dits microduromètres.  1, record 5, French, - microdurom%C3%A8tre
