DEF

An apparatus used for making hardness tests on timber.

CONT

Hardness.... With the change to SI units a special hardened steel tool(known as the Janka hardness tool) rounded to a diameter of 11. 3 mm(projected area 100 mm2) is embedded to one-half of its diameter into the(20 mm) test piece. This tool has a device embodying an electrical contact which rings a signal bell when the correct depth of penetration has been reached... The hardness test is performed... on the static bending specimen... there is a very good correlation between the side hardness of timber, as determined by the Janka hardness tool, and its compression strength perpendicular to the grain.

Record 2 1991-10-22

English

Subject field(s)
  • Measuring Instruments
CONT

Anti-friction plates or caps or other mechanical means shall be used on a [weighing] machine to limit the side play or movement of knife-edges on their bearings or in their loops and shall be of such hardness, smoothness and design as to reduce contact friction to a minimum.

OBS

Consolidation of Weights and Measures Regulations, March 1990, s. 154.

French

Domaine(s)
  • Appareils de mesure
CONT

Des plaques anti-friction ou des chapeaux ou d'autres moyens mécaniques doivent être utilisés pour limiter le jeu latéral ou le mouvement des bords et des couteaux sur leurs coussinets ou dans leurs anneaux, et ils doivent être d'une dureté, d'un poli et d'un modèle propres à réduire au minimum les frictions.

Subject field(s)
  • Strength of Materials
OBS

With the change to SI units a special hardened steel tool(known as the Janka hardness tool) rounded to a diameter of 11. 3 mm(projected area 100 mm2) is embedded to one-half of its diameter into the(20mm) test piece... an electrical contact... rings a signal bell when the correct depth of penetration has been reached... the hardness test is performed... on the static bending specimen.... The rate of penetration of the ball is 0. 11 mm/s... there is a very good correlation between the side hardness of timber, as determined by the Janka hardness tool, and its compression strength perpendicular to the grain.

French

Domaine(s)
  • Résistance des matériaux
OBS

Mesure de la dureté des métaux. On applique, sur une surface légèrement polie du métal (...) une bille en acier spécial très dur (...) sous une charge déterminée. Il se forme alors dans la pièce une empreinte permanente, en forme de calotte sphérique [méthode de Brinell] (...)

Record 4 1982-11-16

English

Subject field(s)
  • Copper and Copper Alloys (Metallurgy)
OBS

In an indentation hardness test, the bulge formed on the anvil side of the specimen which indicates that the hardness determination is of questionable accuracy.

French

Domaine(s)
  • Cuivre et alliages du cuivre (Métallurgie)
OBS

Dans le contrôle de la dureté par empreinte, gonflement formé sur la surface inférieure de l'échantillon; indique que la mesure de la dureté est d'une précision douteuse.
