Les poids d’étalonnage (également appelés poids de référence ou poids de test) sont des poids standard connus, fabriqués selon de très hauts niveaux de tolérance et de précision. Ils sont utilisés pour la vérification des performances et l’étalonnage des balances analytiques, des balances de précision et des balances polyvalentes dans les laboratoires de recherche, des contextes pédagogiques ou d’autres environnements professionnels. Ils peuvent également être utilisés pour l’étalonnage d’autres poids « de fortune » ou à la valeur inconnue.
Comment les poids d'étalonnage sont-ils fabriqués ?
Les poids d’étalonnage se présentent sous la forme de simples disques, cylindres, câbles ou feuilles. De manière générale, les poids d’étalonnage sont disponibles sous forme d’ensembles. Ils sont souvent fournis avec une pince brucelles et des gants dans un coffret de protection, pour plus de sécurité. Ces poids peuvent également être vendus individuellement. Les poids d’étalonnage sont souvent fournis avec des marques et des modèles de balance spécifiques, en tant qu’accessoires de compatibilité.
Les poids d’étalonnage sont constitués de métaux tels que le laiton poli, l’aluminium ou autres aciers inoxydables spéciaux. Ainsi, ils jouissent d’une grande durabilité, ne sont pas soumis à la magnétisation et résistent à toute corrosion ou usure susceptible d’affecter leur précision. Les poids d’étalonnage sont disponibles dans une gamme de valeurs nominales allant de quelques milligrammes à plus de 10 kg.Ils peuvent également être fournis avec les certifications ou les déclarations de précision, de conformité et de traçabilité adéquates.
Comment les poids d'étalonnage sont-ils classés ?
Les poids d’étalonnage sont classés par organisation, comme ASTM, OIML et NIST, en fonction de leur niveau de précision. La classification appropriée dépend de la résolution de la balance et du degré de précision nécessaire pour répondre aux besoins de telle ou telle application de pesée spécifique. Les principales classes sont les suivantes :
- les poids d’étalonnage de classe M1 sont utilisés avec des balances standard
- les poids d’étalonnage de classe F1 sont utilisés avec des balances de précision électroniques
- les poids d’étalonnage de classe E2 sont utilisés avec des balances analytiques de haute précision.
